Square D EJB14020SA Molded Case Circuit Breaker – 1 Pole – 20A – Bolt-On – Thermal Magnetic – Shunt Trip

The Square D EJB14020SA is a high-interrupting capacity E-Frame molded case circuit breaker designed for commercial and industrial power distribution systems requiring remote tripping capability. Manufactured by Schneider Electric, this 1-pole, 20A breaker combines dependable thermal-magnetic protection with an integrated shunt trip for remote circuit operation.

The factory-installed shunt trip allows the breaker to be opened remotely, making it well suited for emergency stop systems, safety interlocks, building automation systems, and other applications requiring remote power disconnection. Designed for secure bolt-on installation, the EJB14020SA is compatible with Square D NF panelboards and accommodates both copper and aluminum conductors.

With interrupting ratings up to 100kA at 120VAC and 65kA at 240VAC and 277VAC, this breaker delivers exceptional fault-clearing performance in demanding electrical environments. The breaker also features a Visi-Trip visual indicator for rapid identification of tripped circuits, reducing troubleshooting time and improving maintenance efficiency.
