SENTRON 3VA1010-3ED36-0BH0 — 100 A MCCB, line protection
The Siemens 3VA1010-3ED36-0BH0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, with a 3-pole configuration and a TM210 thermal-magnetic overcurrent release. This is the line-protection version — no voltage trigger or ground-fault monitoring — so it's a straight disconnect for feeders and distribution panels where you need selective coordination downstream of a main breaker. Breaking capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V.
The 100 A rating holds flat from 40 °C through 50 °C, then derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. If this breaker lives in a non-ventilated enclosure near other heat sources, use the 60 °C or 65 °C column — the 90–94 A range still covers a 90 A feeder without oversizing the frame. Footprint is 70 mm deep, 76.2 mm wide, 130 mm tall — standard 3-pole MCCB envelope that clips onto a DIN rail or mounts with screws.
The auxiliary contact block part number for replacement is 3VA9608-0BB11. Mechanical endurance is 15,000 operations — typical for a panelboard MCCB that sees occasional switching, not a daily motor-start duty cycle. For higher cycle counts, look at the 3VA2 series with higher endurance ratings.
