At 690 V it still breaks 11.9 kA, so it covers 480Y/277 V and 600 V delta services without a current-limiting fuse ahead of it. That 160 A holds flat from 40 °C through 50 °C, then derates to 158 A at 55 °C and 150 A at 70 °C — typical for a panel near a furnace or in a hot-climate enclosure where ambient hits 60 °C. The TM240 release means the thermal element is calibrated for a 240 A frame with a 160 A continuous rating; the magnetic pickup trips on short-circuit, not overload. Maximum power loss is 38 W at rated load, which matters when you're sizing ventilation or calculating heat rise in a sealed enclosure. Mechanical endurance is 20,000 operations — not a frequent-switching device; this is a feeder or main breaker, not a motor-starting contactor. Dimensions: 130 mm high, 101.6 mm wide, 70 mm deep — the 4-pole width is about 4 inches, so it occupies four 1-inch module spaces on the rail. The 70 mm depth (2.8 in) clears most standard enclosures; verify clearance for the handle throw and arc-chamber venting at the top. ## Coordination and selectivity note For DC networks, the 3VA device manual covers switching power values — this unit is rated for 600 V DC maximum operational voltage.","metaTitle":"Siemens 3VA1116-4FF46-0AA0 SENTRON MCCB, 160A, 4-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1116-4FF46-0AA0 molded case circuit breaker, 160A rated, 4-pole, TM240 release, 121kA at 240V.
