GACIA SB6L B 3P 50A 6kA Miniature Circuit Breaker MCB 3-Pole B-Curve 50A

The GACIA SB6L B 3P 50A is a high-quality miniature circuit breaker (MCB) designed for reliable overcurrent protection in residential and commercial electrical installations. With a 3-pole configuration, B-curve tripping characteristic, and a rated current of 50A, this MCB ensures safe and efficient operation. Compliant with IEC/EN 60898-1 standards, it offers a breaking capacity of 6kA and is suitable for DIN rail mounting.

Advantages

This MCB provides precise protection against overloads and short circuits, with a B-curve that trips between 3-5 times the rated current, ideal for resistive and lighting loads. Its compact design saves space in distribution boards, while the clear ON/OFF position indicator simplifies status monitoring. The screw terminals accommodate conductors up to 25 mm², ensuring secure connections.
