Product details

SIRIUS S00 power contactor with spring-loaded terminals

For inching or plugging duty (AC-4 at 400 V), the rated operational current is 8.5 A — the figure that governs real-world service life under frequent switching. The main current circuit uses spring-loaded terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded copper, or 2x (24 to 14 AWG). This termination style reduces installation time compared to screw terminals and maintains consistent clamping force over temperature cycles.

At 500 V the contactor is rated for 4.5 kW motor power; at 690 V it handles 5.5 kW. These figures assume the appropriate utilization category — typically AC-3 for squirrel-cage motors unless otherwise specified in the application. This distinction matters when coordinating with the motor branch circuit protective device. Auxiliary contact ratings span the control voltage range: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V DC. The DC switching capacity drops significantly with voltage — verify the load curve if driving DC solenoids or relays.

Electrical endurance will be lower and depends on the switched current and utilization category.

Frequently asked questions

What is the closest functional alternative if 3RT1016-2AD02 is unavailable?

The 3RT1016-2AP02 is a peer variant in the same SIRIUS S00 frame size. The primary difference is the coil voltage and termination — verify coil compatibility and terminal style before substituting. Both share the same mounting footprint and main current ratings.

What are the key electrical ratings for this contactor?

AC-2 motor power is 4 kW at 400 V. AC-4 inching current is 8.5 A at 400 V. Motor power at 500 V is 4.5 kW; at 690 V it is 5.5 kW. Auxiliary contacts handle 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V AC.

What are the physical dimensions and mounting requirements?

Width is 45 mm, height 60 mm, depth 73 mm. It mounts via screw or snap-on onto 35 mm DIN rail per EN 50022. Side-by-side mounting is permitted without spacing.

What terminal type does the main circuit use?

Spring-loaded terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded copper, or 2x (24 to 14 AWG). No screw clamping — terminations are push-in or lever-actuated.
