THED124020 **Older Style** - 20Amp Circuit Breaker

THED124020 **Older Style** - 20Amp Circuit Breaker

When you replace an industrial circuit breaker, getting the details right matters; amperage alone doesn't tell the whole story. Consider the pole configuration, interrupting capacity, physical dimensions, trip mechanism, and terminal connections to ensure the replacement fits the existing equipment. The THED124020 Black Face Circuit Breaker is a 20-amp, 2-pole molded case industrial circuit breaker designed for compatible electrical distribution systems that require the THED configuration. For electricians, electrical contractors, and facility maintenance professionals, matching the correct catalog number helps preserve the original equipment's intended form, fit, and function.
