TE Connectivity Thermal Circuit Breaker 20A Current Rating 1-Pole Direct Mount W51-A152A1-20

TE Connectivity W51-A152A1-20 thermal circuit breaker is engineered for precise and dependable protection in electrical systems requiring current interruption in the range of 5 to 20 amps. With a single pole and direct mount design, it integrates seamlessly into panel assemblies where space efficiency and robust performance are critical.

This breaker features a thermal tripping mechanism that reacts to overcurrent conditions by heating a bimetallic strip to trigger a trip, providing effective safeguarding of downstream equipment. The toggle switch reset actuator allows easy manual reset after fault clearance, minimizing downtime.

Capable of handling rated voltages up to 250 volts AC and 50 volts DC, this circuit breaker is versatile across a wide range of industrial, commercial, and automation applications. The breaking capacity of 1000 amperes ensures it can safely interrupt high fault currents without damage.

The unit’s mounting is direct, utilizing screw terminals facilitating reliable electrical connections and secure installation. Its width of 15.18 mm supports compact panel layouts without sacrificing accessibility.

This W51 series breaker offers trip-free, thermal tripping characteristics, enhancing safety by preventing the breaker from being held closed during an overcurrent event. The medium break time characteristic balances the need for timely disconnection with system coordination requirements.

Certified to CE and RoHS standards, it guarantees compliance with international quality and environmental regulations. Made in China. Designed for 5 to 20 A current range operation. Compact width of 15.18 mm suitable for panel mounting.

Equipped with a thermal tripping mechanism for reliable overcurrent protection. Toggle switch reset actuator enables quick manual reset after tripping. Trip-free thermal characteristic ensures breaker cannot be forcibly held closed during overcurrent.
