The MB1-B-34-615-1-A36-2-C is a single-pole magnetic circuit breaker from Littelfuse with a hydraulic delay mechanism. It is rated for 15A at 250V and is designed for panel-mounted installations. The rocker actuator is non-illuminated, providing manual control of the circuit.
Magnetic hydraulic delay breakers use a solenoid and a fluid-filled delay tube to combine fast magnetic response with a short time delay, helping to avoid nuisance trips during momentary current surges while still clearing sustained overcurrents. This makes the breaker suitable for protecting branch circuits, control equipment, and power distribution systems where a compact single-pole form factor is required.
The 1-pole configuration protects a single conductor within the rated voltage and current. Panel mount mounting simplifies integration into enclosures, and the rocker actuator gives clear on/off control without illumination.
