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.
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.
