GACIA N8BH 10kA C 3P 63A Miniature Circuit Breaker (MCB)

The GACIA N8BH is a high-performance miniature circuit breaker (MCB) designed for reliable overcurrent protection in residential, commercial, and industrial electrical installations. With a rated current of 63 A and a breaking capacity of 10 kA, this three-pole C-curve MCB ensures safe and efficient operation.

Advantages

This MCB offers robust protection against overloads and short circuits, featuring a thermal-magnetic release mechanism. Its compact design allows for easy installation on standard 35 mm DIN rails, saving space in distribution boards. The C-curve tripping characteristic is ideal for circuits with moderate inrush currents, such as lighting and general power outlets.
