Square D EDB34045SA E-Frame Molded Case Circuit Breaker – 3 Pole – 45A – Bolt-On – Thermal Magnetic – 120VAC Shunt Trip

The Square D EDB34045SA is an E-Frame molded case circuit breaker designed for commercial and industrial power distribution systems requiring remote tripping capability. Manufactured by Schneider Electric, this 3-pole, 45A breaker combines dependable thermal-magnetic protection with an integrated 120VAC shunt trip for enhanced control and safety applications.

The factory-installed shunt trip allows remote circuit disconnection for emergency shutdown systems, automation controls, and facility safety applications. Designed for use in NF panelboards, the breaker mounts securely using a bolt-on connection and occupies four pole spaces due to the integrated accessory assembly.

With interrupting ratings up to 25kA and a standard 18kA rating at 480Y/277VAC, the EDB34045SA provides reliable protection against overload and short-circuit conditions. A built-in visual trip indicator enables quick identification of fault conditions, helping reduce maintenance and troubleshooting time.
