Siemens 3VA1116-5ED32-0AG0 — 160 A MCCB with TM210 Release
The Siemens 3VA1116-5ED32-0AG0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated for 160 A continuous current (Iu) with a TM210 thermal-magnetic overcurrent release, configured for line protection in distribution panels. Its interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — figures that drive selectivity coordination in high-fault-current installations. The TM210 release is a fixed thermal-magnetic design with an adjustable long-time delay (tr max. 1 s per the datasheet setting), suited for cable and busbar protection where no electronic adjustment is required.
Thermal Derating and Ambient Temperature
The breaker carries its full 160 A rating from 40 °C through 50 °C ambient. Above that, derating applies: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. Panel builders should factor this curve when the enclosure runs hot — a 160 A bus at 65 °C effectively limits the breaker to 147.2 A continuous.
Dimensions, Mounting, and Auxiliary Contacts
At 130 mm high, 76.2 mm wide, and 70 mm deep, this MCCB fits standard SENTRON panel footprints. The 76.2 mm width (3-pole) matches the 3VA family's modular pitch — no extra DIN rail or busbar rework when swapping within the series. It ships with one auxiliary switch and one trip alarm switch (HP type) factory-installed, providing status feedback for PLC or SCADA without an add-on module. Front-face protection is IP40 — suitable for enclosed distribution boards where the breaker is not exposed to dripping water or dust ingress.
