HHED63B040L - 40Amp Circuit Breaker

HHED63B040L - 40Amp Circuit Breaker

The Siemens HHED63B040L is a 40 Amp, 3-pole SENTRON molded case circuit breaker built around the ED frame and a thermal-magnetic trip unit. One detail worth checking when your matching a replacement is the lug configuration: the HHED63B040L includes LN1E100 lugs on both the line and load sides, with a 10–1/0 AWG copper or aluminum wire range. Its compact 3 x 6.53 x 3.92-inch dimensions also make physical fit easier to verify against the existing breaker. When those requirements line up, the HHED63B040L provides the intended form, fit, and function while maintaining the original equipment configuration.
