EGB24020SA - 20Amp Circuit Breaker with Shunt

EGB24020SA - 20Amp Circuit Breaker with Shunt

When your application requires dependable circuit protection and the ability to remotely trip a breaker, the EGB24020SA delivers both in a single compact solution. This 2-pole, 20-amp E-Frame miniature circuit breaker is designed as a form, fit, and functional replacement for compatible NF panelboards, making it an excellent choice for maintaining existing electrical systems. Built for 480Y/277VAC applications, it combines a thermal-magnetic trip unit with an integrated shunt trip, allowing the breaker to be opened remotely when connected to an external control circuit.

Whether you're replacing an existing shunt trip breaker during routine maintenance or restoring equipment after a fault, using the correct replacement helps minimize downtime and simplifies installation.
