Product Description
CBI QL-1(13) 10A Hydraulic-Magnetic Circuit Breaker – Single Pole, 120V AC, Compact 13mm Width
This used CBI QL-1(13) is a high-performance hydraulic-magnetic miniature circuit breaker (MCB) from CBI-electric Group (Circuit Breaker Industries), a leading global manufacturer of low-voltage circuit protection devices . Designed as part of their QL series, this 1-pole breaker is rated for 10 Amps at 120V AC and is built for industrial control panels, automation equipment, and commercial distribution boards .
The CBI QL-1 utilizes advanced hydraulic-magnetic technology, which ensures precise and stable protection independent of ambient temperature changes . This makes it exceptionally reliable in harsh or fluctuating environments where standard thermal breakers might fail .
Condition Note: This unit is untested and sold as-is. It is a single circuit breaker component; no panel, din rail, or mounting hardware is included unless specified.
