The 10 A at 24 V coil rating means the control circuit needs a supply capable of that inrush; holding power is 3.3 W DC, so once pulled in the coil draw drops sharply. Mechanical endurance is spec'd at 30 million operating cycles, which aligns with high-cycle applications like conveyor or pump stations. For coordination, Type 2 coordination requires a 20 A gL/gG fuse; Type 1 allows a 35 A gL/gG fuse. That's the overcurrent protection the installer needs to match for short-circuit ratings. Spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (0.25 to 1.5 mm²) finely stranded with ferrule. AWG equivalents are 2x (24 to 14). The 72 mm depth, 45 mm width, and 60 mm height fit standard S00 panel layouts. Side-by-side mounting is allowed — no derating gap required — with a 6 mm clearance to adjacent devices at the side.","metaTitle":"Siemens 3RT1316-2BA40 SIRIUS Power Contactor, 4 NO, 4 kW AC-","metaDescription":"Siemens 3RT1316-2BA40 SIRIUS power contactor, Size S00, 4 NO main contacts, 4 kW AC-2 at 400 V, spring-loaded terminals, 45 mm wide.

The key difference is terminal type: the 3RT1316-2BA40 uses spring-loaded terminals, while the 3RT1016-2AP02 uses screw terminals.
