The EZC100F3040 is a 3-pole thermal-magnetic circuit breaker from Schneider Electric's EasyPact EZC100F series, rated 40 A at 40 °C ambient (40 A at 50 °C with the TM-D trip unit). At 400–415 V AC the Icu drops to 10 kA, so verify your system's prospective short-circuit current if you're running a 400 V line. The 690 V rated insulation voltage (Ui) and 550 V max operational voltage (Ue) cover standard 480Y/277 V and 400 V networks. No earth-leakage or neutral protection built in; this is a straight line-protection breaker for 3-phase loads without a neutral conductor.
Deployment context
Fixed mounting on a backplate, front-connected both line and load sides. The 25 mm connection pitch matches standard busbar systems for panelboards. IP20 finger-safe terminals; IK07 impact resistance means it can take a knock during panel assembly. Storage from -35 to 85 °C, operation from -25 to 70 °C.
Current production stage — this is an active catalog line. The EasyPac EZC100F series is widely specified in Asian and European distribution panels; the EZC100F3040 is a standard 40 A 3P variant.
