Not all MCBs Are The Same

Featured Product from E-T-A Circuit Breakers


Protect your Panel with E-T-A's 4230-T MCBs.

E-T-A's 4230-T are single/multi-pole miniature circuit breakers (MCBs) in accordance with EN 60947-2, UL 1077 and UL 489. The 4230-T has toggle actuation, visual status indication, a high rupture capacity and a positively trip-free snap action mechanism.
