The Siemens SENTRON 3VA1010-4ED36-0HC0 is a 3-pole molded case circuit breaker (MCCB) designed for line protection. It carries a continuous current rating of 100 A at 40 °C, derating to 91 A at 70 °C — the full thermal curve is on the nameplate. Breaking capacity hits 121 kA at 240 V, stepping down to 75.6 kA at 415 V and 11.9 kA at 690 V, so it handles high-fault utility feeds without cascading upstream. Insulation voltage is rated 800 V, covering most 480/600 V industrial panels.
Footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — fits standard 3-pole MCCB panel cutouts and DIN-rail adapter kits. Maximum power loss of 25 W means the enclosure needs to shed that heat; keep adjacent devices spaced per Siemens derating guidelines for ambient above 40 °C.
Built with a shunt trip release (STL) and two auxiliary switches HQ — the auxiliary switch design is integral, not a field-added kit. The basic switch assembly carries order code 3VA10104ED360AA0. No undervoltage release, no ground-fault monitoring, no communication function on this variant. Storage temperature range is -40 °C to 80 °C; operating range -25 °C to 70 °C.
