The Siemens SENTRON 3VA2010-6HL32-0JL0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full -25 °C to 70 °C operating range — no derating needed up to the panel ambient limit. It's designed for line protection, meaning it guards feeders and distribution buswork from overcurrent and short-circuit faults, not motor or branch-circuit duty where a different trip curve would apply.
Trip range and breaking capacity
The adjustable thermal-magnetic trip unit covers 150 A to 1200 A — that's a wide window, so you can set it to match the actual load without swapping the breaker. Breaking capacity hits 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. For a 100 A frame, those numbers are well into the high-fault zone; it'll clear a bolted fault on a large transformer secondary without the arc flash escalating upstream.
Auxiliary and release options
This variant ships with a shunt trip (STL) release for remote tripping, plus a 2+1+1 auxiliary switch configuration: two auxiliary switches, one trip alarm switch, and one electrical alarm switch. That's enough to send status back to a PLC or annunciator without adding external interface relays. No undervoltage release, no ground-fault monitoring, no communication module — it's a straight line-protection breaker with remote trip and status feedback.
Physical fit
Dimensions are 181 mm high, 105 mm wide, 86 mm deep. That's a standard SENTRON 3VA frame footprint — it'll drop into a panel laid out for the 3VA1 or 3VA2 series without re-drilling the mounting plate. Power loss is 13.5 W max, so thermal rise in a sealed enclosure is manageable; just don't stack it tight against heat-sensitive components without checking the internal temperature.
