Mitsubishi BH-P 1P 50A No Fuse Breaker

The Mitsubishi BH-P 1P 50A No Fuse Breaker (NFB) is a single-pole, 50 Amp rated no-fuse breaker designed to protect electrical circuits and systems from overloads and short circuits. It features a compact and reliable design, ensuring efficient protection in a wide range of residential, commercial, and industrial applications. The BH-P series is known for its durability, easy installation, and high-performance capabilities.

This No Fuse Breaker (NFB) provides overcurrent protection by disconnecting the circuit in case of a fault condition, such as an overload or short circuit. The breaker does not require external fuses, as it is designed to automatically interrupt the current when it exceeds a preset limit. It is ideal for protecting individual circuits, providing safety against electrical faults while ensuring the continued reliability of the system.

Specifications:

• Model: Mitsubishi BH-P 1P 50A No Fuse Breaker (NFB)
