What's on the manifest
The Siemens SENTRON 3VA2110-6JQ32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to the enclosure's thermal limit. Breaking capacity hits 242 kA at 240 V, drops to 187 kA at 415/440 V, and holds 121 kA at 500 V; at 690 V it still clears 3.7 kA. That's a lot of fault-clearing headroom for a 100 A frame.
Panel fit and fill factor
The 86 mm depth (3.39 in) means it clears most 200 mm-deep enclosures with room for gland plates and rear busbar connections. No special cutout — it bolts onto the backplane or mounts on a DIN rail adapter plate.
Trip curve and adjustability
The thermal-magnetic trip unit is adjustable from 20 A to 100 A full-scale, so one breaker body covers a range of downstream loads. No undervoltage release or voltage trip fitted on this order code — it's a straight line-protection device with ground-fault monitoring via summation current on the L-conductor. Communication function is present, meaning it can talk to a higher-level system for metering or status.
