What this MCCB delivers
The Siemens SENTRON 3VA1110-3GD46-0AA0 is a 4-pole molded case circuit breaker rated for 100 A continuous, with a TM210 thermal-magnetic overcurrent release. It's designed for line protection in distribution panels — the 100 A rating holds from 40 °C up to 50 °C, then derates gradually to 91 A at 70 °C. Interrupting capacity hits 75.6 kA at 240 V and 52.5 kA at 415 V, dropping to 32 kA at 440 V and 11.9 kA at 500 V / 690 V. That's enough headroom for most industrial service-entrance or feeder applications where fault currents are high.
Fit and panel integration
Dimensions are 101.6 mm wide, 130 mm tall, 70 mm deep — a standard 4-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures. Front protection is IP40, meaning it's sealed against tools and small wires but not washdown; keep it inside a cabinet. Rated insulation voltage is 800 V, so it can be used in 480/277 V or 600 V systems without derating the insulation. No undervoltage release or ground-fault monitoring on this variant — it's a straight line-protection breaker.
