Description
SQUARE D QO350VSC6 50A Triple Pole MCB 6KA
The Square D QO350VSC6 is a 50A, triple-pole miniature circuit breaker from the modern QOvs range. Because Schneider Electric designed this as a direct plug-on replacement, it fits perfectly into older Qwikline distribution boards. This Type C breaker effectively protects three-phase systems against overloads, and it also handles moderate inductive loads like lighting or small motors.
