The 4-pole footprint occupies roughly 4 inches of DIN-rail or mounting-plate width. The TM240 release is factory-set; no field adjustment of the thermal curve is intended. The auxiliary switch configuration (1 auxiliary + 1 trip alarm switch HQ) is integrated into the breaker body, so no external add-on block is required for status feedback. ## Thermal derating across ambient temperature At 55 °C it derates to 158 A, at 60 °C to 155 A, at 65 °C to 153 A, and at 70 °C to 150 A. This derating curve is per the datasheet; panel builders should account for internal enclosure temperature rise when sizing the breaker for continuous loads near the 160 A threshold.","metaTitle":"Siemens SENTRON 3VA1116-5EF42-0AF0 MCCB, 160 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA1116-5EF42-0AF0 molded case circuit breaker, 160 A, 4-pole, TM240 release.
