EH3030 - 30Amp Circuit Breaker

EH3030 - 30Amp Circuit Breaker

The EH3030 is a 3-pole, 30 Amp Type EH thermal-magnetic circuit breaker designed as a form, fit, and functional replacement for compatible electrical distribution equipment. Built with a non-interchangeable trip unit, this breaker is rated for a 14 kA interrupting capacity at 480 VAC and is suitable for operation in 40°C ambient conditions. Its thermal-magnetic trip mechanism protects against both overloads and short circuits, helping maintain the intended operation of electrical systems originally designed for this breaker configuration.

Whether you're replacing an existing breaker during scheduled maintenance or restoring service after a breaker failure, the EH3030 is designed to match the original specifications of compatible equipment. Load terminals are included, helping simplify installation in approved applications.
