What this MCCB delivers on the panel
The Siemens SENTRON 3VA2110-6HL32-0KL0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel thermal budgeting in a crowded enclosure. Its interrupting capacity reaches 242 kA at 240 V and 187 kA at 415 V, so it handles high-fault utility feeds without cascading upstream — a key spec for main-breaker or high-SCCR branch positions. The breaker is designed for line protection (not motor or generator protection), with a shunt trip (STL) release and a complement of two auxiliary switches plus one trip alarm and one electrical alarm switch, giving the control system full status feedback.
Physical integration and wiring
The breaker measures 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA frame footprint that fits existing DIN-rail or panel-mount cutouts without rework. Maximum power loss is 10 W, so ventilation in a sealed enclosure is manageable; the operating temperature range of -25 °C to 70 °C covers most indoor industrial environments.
