That 160 A rating holds across the typical panel ambient — you don't lose headroom until you're past 55 °C, where it steps down to 156 A. The TM240 thermal-magnetic release means the thermal trip element is calibrated for a 240 A frame, so this breaker gives you the full 160 A continuous without nuisance tripping on moderate inrush, but the magnetic instantaneous pickup is fixed inside that TM240 design. At 240 V it interrupts 187 kA — that's utility-transformer-grade fault current. At 415 V it's still 121 kA, at 440 V it's 75.6 kA, at 500 V it drops to 30 kA, and at 690 V it holds 17 kA. The 33 W power loss at rated current matters for enclosure thermal rise — in a sealed stainless panel that wattage adds up. It's a line-protection design, so the trip curve and interrupting ratings are optimized for feeder and main breaker duty, not motor-protective coordination. If you're replacing an existing 3VA or older 3VL breaker, verify the mounting plate and bus bar spacing — the 140 mm width is the same as the 3VA 160 A frame, so it drops into the same panel cutout.","metaTitle":"Siemens 3VA1216-5GF42-0AA0 SENTRON MCCB, 160 A, 4-Pole, TM24","metaDescription":"Siemens 3VA1216-5GF42-0AA0 SENTRON molded case circuit breaker, 160 A, 4-pole, TM240 release, 187 kA at 240 V.
