The Siemens SENTRON 3VA2010-5HN36-0AD0 is a 3-pole 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, which simplifies panel thermal budgeting in a crowded enclosure. Breaking capacity is the headline: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. At 690 V the 3 kA rating is a secondary winding protection figure; the real duty is on the 400–480 V industrial range.
The basic switch variant is order code 3VA20105HN360AA0, so if the panel drawing references that bare breaker the 5HN36-0AD0 adds the aux contacts without a separate kit.
Maximum power loss is 13.5 W — negligible for thermal calculations in a multi-breaker panel, but worth noting if the breaker is in a sealed, high-density switchboard with other heat sources.
