THED124030 - 30Amp Circuit Breaker

THED124030 - 30Amp Circuit Breaker

The ABB THED124030 circuit breaker is a 30-amp, two-pole, thermal-magnetic molded-case circuit breaker from ABB's E150 product family. Whether you're maintaining an established commercial electrical installation, servicing industrial equipment, or identifying a matching circuit breaker for an existing assembly, the THED124030 offers clearly defined specifications to help confirm compatibility. Its thermal-magnetic trip design combines long-time overload protection with instantaneous short-circuit protection, while the molded-case construction is built to last under its intended operating conditions. ABB also identifies THED breakers as suitable for reverse-feed applications.
