The Siemens 3VA2110-6HL32-0BH0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That 100 A holds steady even when the panel is pulling radiant heat from adjacent drives or sitting near a furnace zone. The adjustable thermal-magnetic trip module covers 150 A minimum to 1 200 A maximum, so you can set the instantaneous pickup to coordinate with downstream feeders without swapping the breaker body. Breaking capacity runs 242 kA at 240 V, 187 kA at 415/440 V, 121 kA at 500 V, and 3.7 kA at 690 V — the 690 V figure is low, so watch that on a 690 V bus; this is a 480 V-class MCCB for most industrial services. A mechanical trip indicator confirms the breaker has opened on fault vs. manual operation.
Panel fit and thermal reality
That 86 mm depth (3.39 in) is the body only — allow clearance for the UVR coil and auxiliary wiring at the front. Power dissipation at rated load is 12.5 W maximum.
