The Siemens SENTRON 3VA2110-5HL36-0DC0 is a 3-pole molded case circuit breaker rated for 100 A continuous current, designed for line protection in distribution panels. Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the steep drop above 500 V means this breaker is sized for low-voltage main or feeder duty, not 690 V branch circuits. The thermal-magnetic trip unit adjusts between 150 A and 1 200 A, so the 100 A frame carries headroom for coordination studies.
Built-in undervoltage release and auxiliary switching
This MCCB ships with an undervoltage release (UVR) factory-fitted — the breaker trips when supply voltage drops below a set threshold, which is standard for motor feeder protection where an unexpected restart after a dip could injure personnel or damage the load. Two HQ auxiliary switches are also integrated, giving the panel builder a Form-C feedback signal for the PLC or status lamp without adding a separate accessory block.
Thermal performance across the panel ambient range
The 100 A continuous rating holds flat from 40 °C through 70 °C — no derating needed inside a warm enclosure. Operating ambient spans -25 °C to 70 °C; storage range is -40 °C to 80 °C. Power dissipation maxes at 12.5 W, which is modest for a 100 A frame and won't drive a ventilation redesign in a typical IP54 cabinet.
