The Siemens SENTRON 3VA2116-5JQ32-0DH0 is a 3-pole molded case circuit breaker rated 160 A continuous, designed for line protection in distribution panels. Its breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — so at typical 400 V industrial feeds it handles high fault currents without cascading upstream. The thermal-magnetic trip unit adjusts from 32 A to 160 A full-scale, and the breaker carries a trip indicator for quick fault isolation. Current rating holds flat at 160 A from 40 °C through 70 °C ambient — no derating curve to calculate for warm enclosures. Power loss at full load is 28 W maximum, which is manageable for a 160 A frame in a ventilated panel.
Integration & Mounting
The MCCB measures 105 mm wide, 181 mm high, and 86 mm deep — a standard 3-pole frame that fits common panel cutouts and busbar arrangements. It ships with an undervoltage release (UVR) and a factory-fitted auxiliary switch block: 2 auxiliary switches plus 1 trip alarm switch (HQ type). Communication function is onboard, so it can integrate with energy management or remote monitoring systems without an add-on module.
Environmental & Compliance
Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The SENTRON series carries IEC/UL certifications typical for molded case breakers — compliance documentation (RoHS, REACH, UL, IEC) is provided by Siemens with the unit.
