SENTRON 3VA1116-5ED32-0DC0 — 160 A MCCB with TM210 Release
The Siemens SENTRON 3VA1116-5ED32-0DC0 is a 3-pole molded case circuit breaker rated for 160 A continuous current, built around the TM210 thermal-magnetic overcurrent release. It delivers 187 kA interrupting capacity at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V — numbers that govern the available fault current the breaker can safely clear without upstream coordination failure. Rated insulation voltage is 800 V, so it suits 480/277 V and 600 V distribution panels with headroom. The TM210 release provides thermal protection for overloads and magnetic instantaneous trip for short circuits — a standard choice for feeder and branch circuit protection in commercial and industrial switchboards.
Interrupting Capacity and Thermal Derating
At 690 V the interrupting rating drops to 17 kA — verify system fault levels if deploying on 600 V class equipment. The 160 A rating holds flat from 40 °C through 50 °C, then derates to 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 ambient temperature inside a sealed enclosure determines the actual continuous current the breaker can carry without nuisance tripping. The breaker carries an undervoltage release (UVR) as standard and comes with 2 HQ auxiliary switches for status feedback to the PLC or annunciator panel. No communication function or ground-fault monitoring is integrated — those are external add-ons if required.
Panel Fit and Lifecycle
Footprint is 76.2 mm wide × 130 mm tall × 70 mm deep — standard 3-pole MCCB envelope for DIN-rail or panel-mount installation. IP40 on the front face means it is protected against tools and solid objects over 1 mm but not against water ingress; keep it inside a rated enclosure for washdown environments.
