Breaking capacity reaches 121 kA at 240 V AC and remains substantial at higher voltages: 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V — covering most industrial distribution levels without an upstream current-limiting fuse. ## Current Rating vs. Ambient Temperature The 160 A rating holds flat from 40 °C through 50 °C, then derates gradually: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. In a sealed enclosure or high-ambient panel, use the 70 °C figure (150 A) for sizing — the breaker does not trip early, but the thermal element tracks the actual ambient. Dimensions are 101.6 mm wide, 130 mm tall, and 70 mm deep — a standard 4-pole MCCB footprint that mounts on a DIN rail or directly to a backplate via the screw terminals.","metaTitle":"Siemens 3VA1116-4EF46-0AA0 SENTRON MCCB, 160 A, 4-Pole, 121","metaDescription":"Siemens SENTRON 3VA1116-4EF46-0AA0 molded case circuit breaker, 160 A, 4-pole, TM240 release.
