What this MCCB carries
The SENTRON 3VA1010-3ED32-0KA0 is a 3-pole molded case circuit breaker (MCCB) rated 100 A at 40 °C, with a TM210 thermal-magnetic overcurrent release and an integrated shunt trip (STL) for remote tripping. Breaking capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V — enough headroom for most industrial distribution panels where fault current is known and coordinated.
Ratings in context
The 100 A rating holds steady from 40 °C through 50 °C, then derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. If your panel ambient runs above 50 °C, that 9 A drop at 70 °C is the number to size against — not the nameplate 100 A. The TM210 release is a fixed thermal-magnetic type, so no interchangeable trip units; what you see is what coordinates with downstream breakers. Insulation voltage is rated 800 V, and the maximum power loss is 25 W — useful to know for enclosure heat rise calculations if you're stacking several breakers in a sealed panel.
Physical fit
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep. The 70 mm depth is the body only — allow clearance for the shunt trip wiring and any auxiliary contact block you add later. No trip indicator on this variant, so plan for a visual check at the breaker handle or add an external indication contact if the spec calls for it.
