The MU2-B-24-630-3-A21-B-C is a two-pole circuit breaker engineered for reliable overcurrent protection in industrial and commercial electrical systems. Rated for a continuous current of 30 amperes at a maximum voltage of 250 volts, this component safeguards downstream wiring and equipment from damage caused by excessive current flow.
Equipped with a magnetic hydraulic delay trip characteristic, the breaker accommodates temporary inrush currents typical of motors and transformers without nuisance tripping. The magnetic element responds instantly to short-circuit faults, while the hydraulic delay ensures stable operation during sustained overloads. Maintenance is simplified through a durable push-to-reset actuator that restores circuit continuity manually after a fault condition clears.
Mechanically, the unit is constructed for straightforward panel mount installation, allowing direct integration into standard control panels and switchgear assemblies. It carries recognized safety certifications including UL1077, CSA, and CCC approvals, verifying compliance with stringent international standards for equipment-level circuit protection.
The maximum voltage rating is 250 volts.
It contains two poles for dual-circuit protection.
It uses a magnetic hydraulic delay trip characteristic.
The unit is designed for direct panel mount installation.
Power is restored using a manual push to reset actuator.
