Circuit Protection Components Market

Circuit Protection Components Market Analysis

The Circuit Protection Components Market size is estimated at USD 50.96 billion in 2025, and is expected to reach USD 66.92 billion by 2030, at a CAGR of 5.6% during the forecast period (2025-2030).

• Circuit protection involves installing fuses and circuit breakers to protect low-voltage electrical devices during power fluctuations. Regular voltage fluctuations can damage equipment through electrostatic discharge and decrease its overall lifespan. Circuit protection devices (CPDs), such as circuit breakers, electrostatic discharge, fuses, and surge protection devices, are installed to eradicate the threats of electrocution and fire. They are crucial in manufacturing smartphones, computers, laptops, battery packs, communication systems, and portable electronics.
• With the beginning of 5G technology, players are concentrating on upgrading the telecom infrastructure by deploying various pieces of equipment capable of handling the heavy communication load. This equipment is costly and gets damaged due to voltage fluctuation or overheating, resulting in players opting for advanced current protection solutions to reduce product damage and save on additional costs. This high need for overvoltage protection and inrush current limiters from the telecom sector is anticipated to boost the target market's growth.
• For instance, in February 2022, the European Commission announced a new European Chips Act that will enable EUR 15 billion (USD 17.11 billion) in additional public and private investments until 2030.
• In June 2022, KYOCERA AVX launched a new interactive component search tool. It is available as a fixed navigation menu option on the KYOCERA AVX website and accessible via computer, tablet, or smartphone. The new component search tool allows users to quickly and easily explore an extensive selection of the company's proven portfolio of expertly engineered antennas, capacitors, circuit protection devices, filters, couplers, and inductors, as well as view and purchase available stock from its authorized distributor network.
• Further, in May 2022, Metrosil announced the launch of a unique range of pre-assembled CTPU enclosures. It allows for easy installation near the CT secondaries. Metrosil CTPUs, the world's overseeing CT open circuit protection components, can nowadays be ordered conveniently housed in welded sheet steel enclosures.
• The growing trend towards the electrification of vehicles has led to an increased demand for circuit protection devices, which ensure that the vehicle is safe for the passenger during all load situations that include overloads and collision events, short circuits, as well as quick charging and normal driving scenarios. As such, in May 2022, Eaton launched an electric vehicle battery circuit protection solution, the battery disconnect unit (BDU), that features Breaktor circuit protection technology to provide circuit protection in electrified vehicles.

Circuit Protection Components Market Trends

Automotive is Expected to Hold Significant Market Share

• The increase in hybrids and electric vehicles (EV-type cars) is rapidly reducing the environmental burden and increasing the number of ECUs (electronic control units), thereby leading to a more robust demand for electronic components whose miniaturization and further performance improvements have been rising. The growing market for these vehicles will offer further growth opportunities to circuit protection component manufacturers.
• In July 2022, a new set of European rules were introduced, requiring new vehicles to be equipped with a range of mandatory advanced driver-assist systems to improve road safety. The latest safety regulations will help to protect passengers, cyclists, and pedestrians across the EU, saving over 25,000 lives and avoiding at least 140,000 severe injuries by 2038.
• North America is one of the largest automotive hubs in the world. The region's economic growth has impacted the sale of passenger cars and commercial vehicles. Further, according to the US Department of Energy, in May 2024, the United States saw a surge in plug-in vehicle sales, with a total of 124,921 units sold. This figure comprised 98,797 Battery Electric Vehicles (BEVs) and 26,124 Plug-in Hybrid Electric Vehicles (PHEVs). Compared to May 2023, these sales marked a 3.2% increase. Notably, Plug-in Electric Vehicles (PEVs) accounted for 8.74% of all Light-Duty Vehicle (LDV) sales in the country for the month.
• Also, according to the China Association of Automobile Manufacturers, over 965,000 passenger automobiles and around 216,000 commercial vehicles were sold in China in April 2022; these numbers represent a 48% and a 42% decline, respectively, from the previous month. Such huge sales of vehicles will create an opportunity for the studied market to grow.
• Further, according to SIAM India, in 2023, India had produced 4.58 million passenger vehicles. The nation's automotive sector faced a downturn, attributed to both economic challenges and the reverberations of the COVID-19 pandemic, particularly in the financial years of 2020 and 2021.

Asia-Pacific is Expected to Register Significant Growth

• In recent years, India has witnessed remarkable growth in terms of the demand for and consumption of electricity. Growing urbanization and industrialization rates are among the primary factors behind this growth.
• Furthermore, the demand for circuit protection components is also expected to grow across their major end-user industries, such as automotive, consumer electronics, energy, and power, as these sectors are witnessing an upward trend.
• Further, China is also witnessing growth in terms of the adoption of electric vehicles. Growing awareness and various government-led initiatives are driving the sales of electric vehicles in the country. For instance, according to the China Association of Automobile Manufacturers (CAAM), in August 2023, China sold a total of 846,000 new energy vehicles. Of these, 808,000 were passenger electric vehicles, with the remaining 39,000 designated for commercial use. Breaking down the passenger electric vehicle segment further, sales figures stood at 559,000 units for battery electric vehicles (BEVs) and 248,000 units for plug-in hybrid electric vehicles (PHEVs).
• The government is also taking a number of initiatives to promote the growth of the Chinese automotive industry. For instance, in September 2022, the State Taxation Administration (STA), the Ministry of Finance (MOF), and the Ministry of Industry and Information Technology (MIIT) jointly announced the continuation of tax exemptions on purchases of new energy vehicles. Hence, with EV sales expected to sustain a similar growth pattern, the demand for circuit protection components across the country's automotive industry is also expected to grow further during the forecast period.

Circuit Protection Components Industry Overview

The circuit protection components market is fragmented and has several major players. These vendors with significant shares in the market are focusing on expanding their customer base across foreign countries. These companies leverage strategic collaborative initiatives to increase their market shares and profitability.

In May 2023, ProTek Devices announced the launch of a high-powered TVS array for board-level circuit protection in mobile devices, USB fast-charging voltage buses, batteries, and industrial equipment. The newly launched device intends to protect sensitive electronics from latch-up or damage due to electrical overstress, CDE, lightning, and ESD.

In November 2022, Siemens announced that it was expanding its generator circuit-breaker portfolio with a new compact version, the HB1-Compact (HB1-C). The versatile and highly customizable solution uses maintenance-free vacuum switching technology. These developments from vendors were expected to also drive the study market.
