The 160 A rating holds steady from 40 °C up to 50 °C; above that it derates to 144 A at 70 °C, so plan your enclosure ventilation if you're pushing the full ampacity in a hot panel. ## Undervoltage release and auxiliary switching This MCCB ships with an integrated undervoltage release (UVR) — part of the design of the auxiliary release — and two HQ auxiliary switches. The UVR drops the breaker if control voltage falls below its dropout threshold, which is standard for safety circuits that need to disconnect on power loss. The two auxiliary switches give you status feedback (open/closed) for the PLC or a remote annunciator, and they're rated for the same isolation voltage as the main contacts. No trip indicator on the front, so you'll rely on the aux contacts or a separate indication module for fault status.","metaTitle":"Siemens 3VA1116-5EF36-0DC0 SENTRON MCCB, 160 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1116-5EF36-0DC0 molded case circuit breaker, 160 A continuous, 3-pole, 187 kA at 240 V.
