Ratings and what they mean for fit
The 3VA1110-5EE32-0JH0: The 100 A rating at 40 °C holds flat through 50 °C, then derates to 98 A at 55 °C and 91 A at 70 °C — so in a warm panel you lose less than 10 % headroom. The 187 kA at 240 V is the high-end interrupt rating; at 415 V it still breaks 121 kA, and at 690 V it holds 17 kA. That covers most industrial service-entrance and feeder applications where fault current is high. Rated insulation voltage is 800 V, which gives margin for 690 V systems.
Auxiliary and release options
This breaker ships with a shunt trip (STL) release and a configuration of two auxiliary switches plus one trip alarm switch (HQ). That means remote tripping and status feedback are built in — no separate accessory kit needed for basic signaling. The undervoltage release is not fitted, so if you need UVR protection, that would be a separate order.
Physical footprint and panel fit
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard SENTRON 3VA frame size. It mounts on a DIN rail or can be screw-fixed to a backplate. The 70 mm depth leaves room for wiring behind the breaker in a typical 200 mm deep enclosure.
