The Littelfuse MT1-B-34-620-1-B22-B-C is a single-pole magnetic hydraulic delay circuit breaker rated for 20A at 250V. It utilizes a hydraulic-magnetic trip mechanism that provides precise overcurrent protection with minimal ambient temperature sensitivity. The breaker is actuated via a push-pull mechanism, allowing manual reset and trip indication.
The panel mount design simplifies installation in control panels, power distribution units, and industrial equipment. The non-illuminated actuator is suitable for applications where visual indication is not required. This breaker is approved to CCC, CSA, and UL1077 standards, ensuring compliance with international safety regulations.
Typical applications include power supply protection, motor circuits, and battery charging systems. The magnetic hydraulic delay characteristic offers time-delayed tripping for inrush currents while providing fast response to sustained overloads and short circuits. The 1-pole configuration is ideal for single-phase circuits.
