In today’s industrial world, protecting electrical circuits is essential to ensure system reliability and safety. One of the best solutions on the market is the Circuit Protector (CP) from Fuji Electric. Known for its compact design, high performance, and wide compatibility, this product delivers outstanding protection for various industrial applications.
What is a Fuji Electric Circuit Protector?
A circuit protector is a protective device designed to prevent electrical panels and equipment from damage due to short circuits or overloads. Fuji Electric offers high-quality circuit protectors specifically developed for the needs of modern industries.
These protectors are built to respond quickly and accurately during electrical faults, minimizing system downtime. Their slim and modular design not only saves space in control panels but also simplifies installation.
Two Main Series: F Series and D Series
Fuji Electric provides two main types of circuit protectors, F Series and D Series, tailored to different industrial needs.
1. F Series – Super Slim and Feature-Rich
The F Series is ideal for those who need a super slim circuit protector. With a width of only 17.5 mm, it saves up to 30% panel space compared to conventional models — perfect for modern, compact control panels.
Key features of the F Series:
-
Supports both AC and DC power systems.
-
Comes with optional auxiliary and alarm switches for enhanced monitoring and safety.
-
Offers inertia delay models for systems that require delayed response.
-
Certified by major global standards such as UL (USA), TÜV (Germany), and CCC (China).
2. D Series – Reliable Standard Protection
For basic but dependable circuit protection, the D Series is a solid choice. With a breaking capacity of 1–2.5 kA, it’s suitable for general control circuits and industrial equipment protection.
The D Series also complies with various international safety standards, making it a reliable option for global industrial use.
