The mechanical endurance of 30 million operations means it outlasts most machines it's wired into. The S00 frame is 45 mm wide, 57.5 mm tall, and 72 mm deep — a compact footprint that leaves room for auxiliary contact blocks or an overload relay on the same DIN rail. Side-by-side mounting is allowed with a 6 mm gap at the side for heat dissipation. For type 2 coordination, use a 20 A gL/gG fuse; for type 1, a 35 A gL/gG fuse. The screw terminals are standard for panel builders — no special tooling needed.","metaTitle":"Siemens 3RT1316-1BA40 SIRIUS S00 Power Contactor, 4 NO, 10 A","metaDescription":"Siemens 3RT1316-1BA40 SIRIUS S00 power contactor, 4 NO main contacts, 10 A AC-12, 4 kW AC-2 at 400 V.
