The 3VA1010-4ED36-0KA0: Breaking capacity is the headline here: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. That 121 kA at 240 V means it handles high-fault utility feeds without needing a current-limiting upstream breaker — useful when you're tying into a transformer secondary or a bus with stiff source impedance. The 75.6 kA at 415 V covers most European industrial distribution panels. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — a standard 3-pole MCCB footprint that drops into SENTRON panelboards and most DIN-rail adapter kits. IP40 on the front means it's splash-protected in the panel but not washdown-rated; keep it behind a gland plate or enclosure door in wet environments.
Thermal derating and operating range
The 100 A rating holds flat from 40 °C through 50 °C — no derating needed in a typical warm panel. At 55 °C it drops to 96 A, at 60 °C to 94 A, at 65 °C to 92 A, and at 70 °C to 90 A. If your panel ambient sits above 50 °C, size the load side accordingly or bump to the next frame. Operating ambient spans -25 °C to 70 °C; storage range is -40 °C to 80 °C.
Auxiliary releases and connectivity
This variant ships with a shunt trip (STL) auxiliary release — part number 3VA9688-0BL33 for the integrated trip unit. No undervoltage release, no auxiliary contact block, no communication module, no ground-fault monitoring. The shunt trip lets you remotely trip the breaker via a control signal, useful for emergency-stop circuits or PLC-driven load shedding. Voltage trigger is present, so it responds to a separate control voltage rather than a mechanical latch.
Sourcing and lifecycle
Current production — no LTB or phase-out on this code. That means it's still a standard catalog item, not a surplus gamble. We source it to order against an RFQ; availability and current pricing get confirmed at quote time. If you're freezing a BOM for a multi-panel run, this one won't trigger a last-time-buy scramble.
