What this 3VA1116-5ED36-0BC0 is and what it does
The Siemens SENTRON 3VA1116-5ED36-0BC0 is a 3-pole molded case circuit breaker (MCCB) rated at 160 A continuous current with a TM210 thermal-magnetic overcurrent release. It is designed for line protection in distribution panels and motor branch circuits where high interrupting capacity is needed — 187 kA at 240 V AC, 121 kA at 415 V, and 76 kA at 440 V. The IP40 front protection means it is suited for installation inside a panel enclosure where splash or tool contact is not expected on the front face.
Key ratings and what they mean for your panel
The 160 A rating holds across ambient temperatures from 40 °C to 50 °C without derating — at 55 °C it still carries 158 A, and at 70 °C it is 150 A. That thermal stability matters when the breaker sits in a crowded enclosure next to other heat sources. The interrupting ratings at different voltages tell you the fault-clearing capability: at 240 V it handles 187 kA, enough for high-fault utility feeds; at 690 V it still clears 17 kA. The TM210 release provides fixed thermal and magnetic trip settings — no interchangeable trip units, which simplifies ordering but locks you into that curve.
Integration notes
The breaker measures 130 mm high, 3 in wide, and 2.8 in deep — a standard footprint for this class of SENTRON MCCB. It mounts on a DIN rail or panel base. The front IP40 rating means it is not intended for wet or dusty environments; keep it inside a sealed enclosure. The auxiliary contact version (2 HQ switches) and the UVR are wired separately; the UVR coil must see rated voltage to allow closing.
