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.
Dimensions and Panel Fit
130 mm high, 76.2 mm wide, 70 mm deep. 3-pole, fits standard SENTRON mounting footprint. Front protection is IP40, so it's fine inside a closed panel but not rated for washdown or outdoor exposure.
Auxiliary and Release Options
This unit ships with an undervoltage release (UVR) as standard — the auxiliary release design is UVR, so if the control voltage drops, the breaker trips immediately, which is common for emergency-stop chains or undervoltage protection schemes. It also includes two auxiliary switches HQ (high-qualified) for status feedback to a PLC or indication lamp; the integrated auxiliary trip order code is 3VA9608-0BB24, which is the factory-fitted internal accessory. Latching endurance rated at 15,000 operations.
