The BA1-B0-24-450-421-C is a 1-pole magnetic hydraulic circuit breaker manufactured by Littelfuse Inc. It is rated for 5A at 277V, providing reliable overcurrent protection in a variety of applications. The hydraulic delay mechanism ensures precise trip characteristics suitable for moderate load protection.
This circuit breaker utilizes a magnetic hydraulic (hydraulic delay) trip mechanism, which offers a time-delayed response to momentary overcurrents and instantaneous trip on high currents. Its single-pole design makes it ideal for single-phase circuits commonly found in lighting control, HVAC equipment, and industrial machinery.
Mechanically, the breaker features a lever actuator for manual operation and reset, and is designed for panel mounting. It has no illumination. The component is listed as RoHS3 compliant, REACH unaffected, and has an MSL of 1. It holds safety approvals from CCC, CSA, and UL, ensuring compliance with international standards.
