Product details

Siemens SENTRON 3VA1110-4EF36-0DC0 — 100 A MCCB for Line Protection

The Siemens SENTRON 3VA1110-4EF36-0DC0 is a 3-pole molded case circuit breaker (MCCB) rated 100 A at 40 °C, designed for line protection in distribution panels and industrial switchboards. Its breaking capacity reaches 121 kA at 240 V AC, 75.6 kA at 415 V, and 11.9 kA at 690 V — figures that govern its ability to clear a fault without upstream devices needing to trip. Rated insulation voltage is 800 V, and the unit carries an undervoltage release (UVR) plus two auxiliary switches HQ as standard — so it can signal its status to a PLC or safety circuit without an add-on module. Maximum power loss is 27.5 W; the thermal derating curve runs from 100 A at 40 °C down to 91 A at 70 °C, which matters when the breaker is enclosed in a crowded panel with limited airflow.

Physical Fit and Panel Integration

Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth — a standard MCCB footprint that fits most DIN-rail or panel-mount enclosures without requiring a sub-panel adapter. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The storage limit governs handling and warehousing, not running conditions.
