The Siemens SENTRON 3VA1116-5EF36-0AE0 is a 3-pole molded case circuit breaker (MCCB) built for line protection, with a TM240 thermal-magnetic release and a continuous current rating of 160 A that holds steady up to 50 °C — above that, it derates to 150 A at 70 °C, so if your panel runs hot, that's the number to spec against. Interrupting capacity is the headline here: 187 kA at 240 V AC, dropping to 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V — that's serious fault-clearing muscle for high-available-fault-current distribution panels, and the 800 V rated insulation voltage (Ui) means the internal clearances are built for 690 V systems without derating. It ships with four HQ auxiliary switches fitted (design-of-auxiliary-switch field), so you get status feedback without buying add-on blocks — handy for a panel builder who wants to wire the breaker's open/closed and trip signals into a PLC or annunciator on day one.
Integration & Mounting
The 3VA1116-5EF36-0AE0 measures 130 mm tall, 76.2 mm wide, and 70 mm deep — standard SENTRON 3VA form factor for 160 A frames. It mounts on a DIN rail or can be screw-fixed to a backplate; the 3-pole footprint matches the same cutout as other 3VA breakers in this current class, so swapping into an existing panel that was laid out for a 3VA1110 or 3VA1112 is a straight mechanical drop-in — no re-drilling, no bus-bar rework. Power loss is 38 W max at rated load — that's the heat you need to vent in the enclosure. No undervoltage release, no ground-fault monitoring, no communication function on this variant; it's a straight thermal-magnetic breaker with auxiliary contacts only.
