Breaking capacity across voltages — where it fits
The 3VA1010-2ED36-0JH0: This MCCB delivers 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and holds 7.5 kA at both 500 V and 690 V. That 52.5 kA at 240 V is the headline number — it's built for high-fault panels on 240 V line-to-line or 240/120 V split-phase services where upstream transformer capacity is substantial. At 415 V it still clears 32 kA, which covers most European industrial distribution boards without needing a current-limiting upstream breaker.
Thermal derating — don't guess the real ampacity
Rated 100 A from 40 °C through 50 °C ambient, then it tapers: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. If your panel internal temperature runs hot — say a sealed enclosure near a motor drive — you lose 9 A off the nameplate by 70 °C. That's a 9% derate; plan your load wiring and upstream protection accordingly.
Built-in accessories — shunt trip and auxiliary switches
Factory-fitted with a shunt trip (STL) release for remote tripping, plus two auxiliary switches and one trip alarm switch (HQ). That means you can wire it for remote shutdown from a safety PLC or E-stop circuit without adding an external shunt trip accessory later. The auxiliary switches give you status feedback — open/closed and tripped — back to the control system.
Dimensions and panel fit
Measures 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or screw-mounted panel layouts. The 70 mm depth means it won't crowd the gland plate in a 200 mm deep enclosure. Power dissipation maxes at 25 W, so factor that into your thermal budget if you're packing several breakers in a small cabinet.
