MA1-B-14-615-1-A57-A-C

The MA1-B-14-615-1-A57-A-C is a single-pole circuit breaker designed for reliable overcurrent protection in electrical systems. Manufactured by Littelfuse Inc., this component is rated for 15 amperes at a maximum voltage of 250 volts. The unit utilizes a magnetic hydraulic delay trip mechanism, which provides precise protection against sustained overloads while tolerating brief inrush currents typical of many industrial loads.

This breaker is configured for panel mounting, making it suitable for integration into control panels, power distribution units, and equipment enclosures. It features a standard rocker-style actuator for manual switching and status indication, though it does not include built-in illumination. The device carries multiple international safety approvals, including UL1077, CSA, and CCC certifications, ensuring compliance with various regional standards for supplementary protectors.

Engineers and procurement specialists selecting this part should note its straightforward mechanical interface and robust electrical ratings. The absence of illumination simplifies the design for applications where external indicator lights are preferred or already integrated into the panel layout. Its magnetic hydraulic delay characteristic makes it well-suited for circuits requiring tolerance to temporary current spikes without nuisance tripping.
