At 40 °C it carries a full 125 A continuous; that rating holds flat through 50 °C, then derates to 114 A at 70 °C — useful when the breaker sits in a warm enclosure next to other heat sources. The interrupting ratings climb 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. That gives you selectivity headroom on most low-voltage distribution panels without stepping up to a larger frame. The 3VA1112-3EF46-0AA0 occupies 101.6 mm width, 130 mm height, and 70 mm depth — a compact 4-pole footprint for a 125 A frame. Front protection is IP40, so the breaker is suited for enclosed panel mounting where tools and fingers stay out.","metaTitle":"Siemens 3VA1112-3EF46-0AA0 SENTRON MCCB, 125 A, 4-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1112-3EF46-0AA0 molded case circuit breaker, 125 A at 40 °C, 4-pole, TM240 release, 75.6 kA at 240 V.
