SENTRON 3VA2110-7MS36-0AB0 — 100 A MCCB for Starter Protection
The Siemens SENTRON 3VA2110-7MS36-0AB0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, designed specifically for starter protection in motor control centers and distribution panels. Its interrupting capacity reaches 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V — covering high-fault scenarios common in industrial power distribution. The breaker ships with two HP auxiliary switches integrated (design of auxiliary switch: 2 auxiliary switches HP), and the supplied basic switch carries order code 3VA21107MS360AA0.
Current Rating and Thermal Performance
The continuous current rating holds at 100 A across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to 70 °C, which simplifies panel thermal budgeting. Maximum power loss is 10 W, low enough that ventilation requirements are minimal for a breaker of this rating. Operating temperature range spans -25 °C to 70 °C; storage range is -40 °C to 80 °C, covering most indoor and conditioned outdoor installations.
Dimensions and Panel Fit
The breaker measures 181 mm high, 105 mm wide, and 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or direct-mount panel layouts without requiring extra enclosure depth.
