The DC magnet holds at 3.3 W, with a pickup threshold of 0.85 x rated voltage and an overexcitation limit of 1.1 x rated voltage. The S00 footprint is compact at 45 mm wide, 57.5 mm tall, and 72 mm deep — leaves room on a crowded DIN rail for auxiliary blocks or overload relays. Screw-type terminals on the main circuit accept 2x (0.5 to 1.5 mm²) solid, 2x (0.75 to 2.5 mm²) stranded, or up to 2x (0.75 to 4 mm²) max. AWG equivalents: 2x (20 to 16), 2x (18 to 14), 1x 12. Finely stranded conductors require core-end processing. Front and terminal protection is IP20. ## Ratings and coordination The DC coil operates over a 48 V nominal with a pickup threshold of 0.85 (40.8 V) and can tolerate 1.1 x (52.8 V) for overexcitation. Switching capacity on the DC side: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, 3 A at 400 V. For AC-12 resistive loads, the maximum operating current is 10 A. Type 2 coordination requires 20 A. Maximum altitude is 2 000 m. Mechanical endurance is typical 30 million switching cycles. The contactor carries a reference code Q per DIN EN 81346-2.","metaTitle":"Siemens 3RT1316-1BW40 SIRIUS S00 Power Contactor, 4 NO, DC C","metaDescription":"Siemens SIRIUS 3RT1316-1BW40 power contactor, size S00, 4 NO main contacts, DC coil 48 V, 4 kW at AC-2 400 V.

However, verify the coil voltage — the 3RT1316-1BW40 uses a 48 V DC coil, while the 3RT1016-1AG61 may differ. The main contact configuration also differs: the 3RT1316-1BW40 has 4 NO contacts versus the 3RT1016-1AG61's 3 NO + 1 NC arrangement.
