BY05-32 MCB Single Modular 3KA Miniature Circuit Breaker
product detail
Product Overview
- The BY05-32 series single modular 3kA miniature circuit breaker (MCB) is a compact and efficient device designed to provide overload and short-circuit protection in single-phase electrical systems. With a rated current of up to 32A and a 1P+N pole configuration, this breaker integrates both the live (L) and neutral (N) poles in a single modular design, simplifying wiring and installation. It operates at a rated voltage of 240V with a frequency of 50/60Hz, making it compatible with global electrical standards.
- A key feature of the BY05-32 series is its unique design where the neutral pole (N) is not equipped with overload or short-circuit protection. This ensures that while the live pole (L) is fully protected, the neutral pole provides a reliable connection without interrupting the current flow in non-fault conditions. This design is particularly suitable for residential and light commercial applications, where compact, efficient, and safe circuit protection is essential.
- The MCB is constructed with high-quality, flame-retardant plastic housing, enhancing safety by reducing fire risks under extreme conditions. Its robust design also protects the internal components from mechanical damage, ensuring durability and long service life. The single modular width allows for efficient use of space in electrical panels, making it ideal for installations where compact solutions are required.
