The Siemens SENTRON 3VA2010-5HL36-0AJ0 is a 3-pole molded case circuit breaker rated for 100 A continuous current, with a maximum breaking capacity of 187 kA at 240 V AC. It is designed for line protection in industrial distribution panels, with no ground-fault monitoring or undervoltage release built in.
Breaking capacity and selectivity
At 240 V the breaker interrupts 187 kA; at 415 V and 440 V that drops to 121 kA, then 75.6 kA at 500 V, and 3 kA at 690 V. For a 100 A feed, the 187 kA figure at 240 V gives substantial headroom for high-fault utility feeds or transformer secondaries — selectivity coordination downstream is straightforward because the upstream device clears fast without nuisance tripping. The 100 A rating holds flat across the full ambient range from 40 °C to 70 °C — no derating needed in a warm enclosure or near other heat sources.
Mounting and panel fit
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep. The 86 mm depth fits standard MCCB mounting plates and leaves room for rear-connected busbars or cable lugs without forcing a deeper enclosure. The auxiliary switch block is factory-configured as 2 auxiliary switches plus 1 trip alarm switch (HP type). No communication module or voltage-trip accessory is included — this is a straight line-protection breaker with local indication only.
