It carries 3 normally-open and 1 normally-closed contact, rated for 25 A operational current at 230 V AC. The coil accepts 230 V AC or 220 V DC, with a maximum rated voltage of 400 V. The 25 A rating at 230 V AC covers resistive and moderate inductive loads typical of panel lighting, small heaters, and valve solenoids. The 400 V maximum rating means it can switch loads on a 400 V three-phase line, but the contact arrangement and current rating govern the actual load size. The manufacturer notes that spacers are required between units for heat dissipation — a detail to account for during panel layout to avoid derating. The part carries IP20 protection, suitable for use inside enclosed control panels where no washdown or dust ingress is expected. The SENTRON brand indicates compliance with Siemens standard quality and testing protocols for residential and light commercial installations. ## Integration Notes The 35 mm width and 64 mm installation depth fit standard distribution board cutouts. The design accepts supplementary devices, allowing add-on auxiliary contact blocks or surge suppressors without changing the base contactor. For a 3-pole load, total dissipation is approximately 6.6 W — within the range that standard enclosure ventilation handles, but the spacer requirement still applies.","metaTitle":"Siemens 5TT5031-6 SENTRON Insta Contactor, 25 A, 230 V AC Co","metaDescription":"Siemens 5TT5031-6 SENTRON insta contactor, 3 NO + 1 NC, 25 A at 230 V AC, 400 V rated.
