Siemens SENTRON 3VA1110-3EF36-0CC0 — 100 A MCCB with TM240 Release
The Siemens 3VA1110-3EF36-0CC0 is a SENTRON molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current Iu of 100 A across ambient temperatures up to 50 °C before derating begins — at 55 °C it still holds 96 A, and at 70 °C it delivers 90 A, so a panel running warm still has headroom for the full load. Breaking capacity is specified at four voltage levels: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V — the 415 V figure is the one most panel builders will size against for European 400 V distribution, and it comfortably covers most transformer-fed fault currents in a standard industrial switchboard. The overcurrent release is a TM240 thermal-magnetic type, meaning it uses a bimetal strip for overload protection and a solenoid for short-circuit response — no electronic adjustment, no communication module, just a fixed curve that suits motor branch circuits and general distribution where you don't need to dial in the trip setting.
130 mm high, 76.2 mm wide, 70 mm deep. 3-pole, fits standard SENTRON mounting footprint.
Latching endurance rated at 15,000 operations.
