Eaton PXL-C50/3 Miniature Circuit Breaker, 3-Pole, C Curve, 50 A, 400 V AC, 10 kA, DIN Rail 236431

Protecting electrical circuits from overload and short-circuit currents is essential in any distribution board. The Eaton PXL-C50/3 is a 3-pole miniature circuit breaker (MCB) with a C tripping characteristic, rated at 50 A and 400 V AC, providing reliable protection for commercial and industrial installations.

Who is it for

This MCB is intended for electricians and panel builders who need a robust, DIN-rail-mounted circuit breaker for three-phase circuits with moderate inrush currents, such as motors, lighting, and general power distribution.
