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.
Breaking capacity across voltages
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. For a 480 V panel, the 32 kA at 440 V is the closest published figure — expect similar headroom at 480 V. The 11.9 kA at 690 V covers industrial 600 V class installations, but verify the available fault current doesn't exceed that.
Thermal derating and panel fit
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. If the panel ambient runs above 50 °C, the 5 A per step derating is predictable enough to size the bus without guessing. The 70 mm depth and 76.2 mm width (3 inches) fit standard MCCB panel cutouts — no special adapter plate needed for most enclosures.
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. Rated insulation voltage is 800 V, with a maximum operating voltage of 500 V DC if used in DC networks (per the 3VA device manual).
