Description

Engineered for legacy commercial applications, the Siemens EE2B040 is a 2-pole, 40-amp molded case circuit breaker. It features a thermal-magnetic trip unit with fixed long-time and instantaneous functions for reliable performance. This bolt-on breaker mounts into older Siemens FC, FE, CDP, P2, and P3 panelboards. For modern upgrades, this unit is superseded by the ED22B040 and ED42B040 models. Rated for 10kAIC at 240VAC, it provides essential short-circuit protection for aging systems.
