Industrial QZD38101 Circuit Breaker

The QZD38101 is a three-pole, 1-amp circuit breaker in CBI-Electric's QZ Series (QZD38101), designed to protect three-phase circuits from overcurrent with a D-type trip curve. This UL 1077-listed device sits among QZ family 3P configurations that cover currents from 0.1 A up to 60 A, providing consistent protection while offering interchangeability with other QZ models in industrial panels and enclosures. The three-pole design ensures protection across all three phases and supports reliable operation in motors, conveyors, and other inductive loads common in manufacturing and commercial settings, where fast yet stable fault clearing is essential. The QZ Series designation indicates a standardized protection device whose part number—QZD38101—identifies a 3-pole, 1-amp rating within this family, aligning with the range of 1P, 2P, and 3P variants that architects of electrical systems frequently specify for compact, scalable control architectures.
