MCCB with TM210 release — 100 A continuous, 52.5 kA at 240 V
The Siemens 3VA1010-2ED36-0BH0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current (Iu) with a TM210 thermal-magnetic overcurrent release. Its breaking capacity reaches 52.5 kA at 240 V AC, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — figures that define the available fault current it can safely interrupt at each voltage level without upstream coordination failure. The 100 A rating holds across ambient temperatures from 40 °C to 50 °C without derating; above that, the curve steps down to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. For a panel running warm — say, a packed enclosure near a drive cabinet — that derating profile is the number that governs the actual load you can protect.
Physical fit and panel integration
The 3VA1010-2ED36-0BH0 measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a 3-pole footprint that mounts on a DIN rail or directly to a backplate via the SENTRON mounting accessories. The front face carries an IP40 protection rating, suitable for enclosed distribution boards where tools or fingers are the main contact risk.
Auxiliary contacts and undervoltage release
This MCCB ships with 2 auxiliary switches plus 1 trip alarm switch (HQ configuration) and an integrated undervoltage release (UVR). The auxiliary contact block is specified as order code 3VA9608-0BB11 for replacement or expansion. The UVR drops the breaker on loss of control voltage — standard for emergency-stop circuits or undervoltage protection schemes where the load must not auto-reclose.
Rated insulation voltage and storage limits
Rated insulation voltage (Ui) is 800 V, which sets the maximum system voltage the breaker's insulation system is designed to withstand continuously. Storage temperature range is -40 °C to 80 °C; operating ambient spans -25 °C to 70 °C. The storage limit governs handling and warehousing, not running conditions.
