Mini Circuit Breakers

Model QL DIN-rail-mount miniature circuit breakers (MCBs) measure only 0.5-in. wide, are available in current ratings from 0.5 to 25 A in 0.5 increments, and are UL 489 approved.

MINI CIRCUIT BREAKERS

The QLs are hydraulic magnetic MCBs, therefore they do not require the temperature variation compensation associated with most thermal breakers. The devices operate in temperatures from 40 to 140°F. The QL is suitable as a replacement for low-current fuses and a wide range of equipment protection.
