The Siemens 3VA1116-3EE36-0AA0 is a SENTRON 3VA1 molded case circuit breaker (MCCB) in a 3-pole configuration, rated 160 A continuous at 40 °C through 50 °C with no derating needed in that band. It carries the TM220 thermal-magnetic trip unit — fixed thermal and magnetic settings, no electronic adjustment — so it's a straight line-protection breaker for distribution panels, not a selective or ground-fault variant.
This MCCB's interrupting capacity varies with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
Continuous current holds at 160 A from 40 °C to 50 °C, then steps down: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C.
Integration notes
The 3VA1116-3EE36-0AA0 mounts in a standard MCCB footprint — 130 mm height, 76.2 mm width, 70 mm depth — and accepts the SENTRON accessory range (shunt trip, auxiliary switch, motor operator). The TM220 trip unit is non-interchangeable; what you order is what you get for overload and short-circuit protection.
