It is configured for line protection — the standard duty for a main or feeder breaker in a distribution panel. The 75.6 kA interrupting rating at 240 V AC gives headroom for high-fault utility feeds; at 415 V it still breaks 52.5 kA, and at 690 V it holds 11.9 kA. Above that it derates: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. Maximum power loss is 38 W. The N-conductor protection is set at 50% of the phase rating. For a panel builder, the 70 mm depth and 101.6 mm width mean it fits standard SENTRON mounting footprints; the IP40 front protection is typical for enclosed distribution boards.","metaTitle":"Siemens 3VA1116-3FF42-0AA0 SENTRON MCCB, 160 A, 4-Pole, TM24","metaDescription":"Siemens 3VA1116-3FF42-0AA0 SENTRON 4-pole MCCB, 160 A continuous, TM240 release, 75.6 kA at 240 V.
