CBI Electric QZ-1(13)-2-20A | 20A Single Pole Hydraulic-Magnetic Circuit Breaker, 13mm DIN Rail Mount

The CBI QZ-1(13)-2-20A is a high-density supplementary protector designed for precision overcurrent protection. Utilizing hydraulic-magnetic technology, this breaker is unique because it is unaffected by ambient temperature—it will not "nuisance trip" in hot environments or fail to trip in cold ones. Its 13mm width is roughly 30% slimmer than standard 18mm breakers, allowing for significantly more circuits in the same DIN rail space
