THED124020WL **Older Style** - 20Amp Circuit Breaker

THED124020WL **Older Style** - 20Amp Circuit Breaker

When you're replacing a circuit breaker in an existing industrial electrical system, the details matter. Finding the right amperage is only the beginning. Pole configuration, interrupting capacity, physical dimensions, trip mechanism, and terminal connections all affect whether a replacement fits the existing equipment. The THED124020WL Black Face Circuit Breaker is a 20-amp, 2-pole molded case industrial circuit breaker designed for compatible electrical distribution equipment requiring the THED configuration. For electricians, electrical contractors, and facility maintenance teams, matching the THED124020WL catalog number is an important step toward maintaining the original equipment's form, fit, and function.
