What this MCCB carries and where it fits
The Siemens SENTRON 3VA1010-3ED36-0AE0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C, with a TM210 thermal-magnetic overcurrent release. It's a line-protection device — no undervoltage release, no ground-fault monitoring, no communication module, no trip indicator. The interrupting capacity hits 75.6 kA at 240 V and 52.5 kA at 415 V, which covers most industrial distribution panels and motor control center feeders. The 70 mm depth and 76.2 mm width mean it fits standard SENTRON mounting bases without crowding the gland plate.
Derating and thermal limits — the real usable current
At 40 °C, 45 °C, and 50 °C the breaker holds the full 100 A. Above that it starts to taper: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. If your panel ambient runs hot — say, a sealed enclosure near a furnace line — the 90 A floor at 70 °C is the number to size against, not the 100 A label. The operating range spans -25 °C to 70 °C, storage from -40 °C to 80 °C.
Auxiliary contacts and release options
This variant ships with 4 auxiliary switches (HQ type) — enough for status feedback to a PLC or to drive a remote indication lamp. No auxiliary release (shunt or undervoltage) is fitted; if you need one, you're looking at a different order code. The TM210 release is fixed, not adjustable for long-time pickup, but the tr max is set at 1 s.
Panel integration notes
Mounts on a standard SENTRON base or DIN-rail adapter. IP40 on the front — fine for a clean indoor panel, not for washdown zones. The 130 mm height and 70 mm depth leave room for cable bends below the line terminals. No communication function, so no fieldbus wiring to pull; just power and load cables plus the auxiliary contact loop.
