The Schneider Electric EZC100B3060 is a 3-pole thermal-magnetic circuit breaker from the EasyPact EZC100B line, rated 60 A at 40 °C ambient. The TM-D trip unit handles overload and short-circuit protection — no earth-leakage module inside. It is a Category A breaker, meaning it is not specifically designed for high-frequency switching but for standard distribution protection. Breaking capacity varies by voltage: 10 kA Icu at 110–130 V AC, 10 kA at 220–240 V, 7.5 kA at 380–415 V, 5 kA at 440 V, and 2.5 kA at 550 V AC. The 5 kA at 440 V means this breaker is not a fit for heavy 480 V industrial mains where SCCR requirements exceed 10 kA; you would step up to the EZC250 or EZC400 frame for that. Rated insulation voltage (Ui) is 690 V AC, and rated operational voltage (Ue) is 550 V AC.
Mounts on a backplate with a fixed mounting mode. The connection pitch is 25 mm, and both upside and downside connections are front-facing. Dimensions: 75 mm wide, 130 mm high, 60 mm deep. Mechanical durability is rated at 13,000 cycles. That is standard for a molded-case breaker in this class — not a high-cycle switching device, but fine for a distribution panel where it operates a few times a year.
