Product details

Siemens 3RT2016-1BJ81 — SIRIUS Power Contactor, Size S00, 72 V DC Coil

It carries a 72 V DC coil with screw-type terminals and is rated for 10 A at 24 V DC and 1 hp at 230 V.

Ratings and Performance

DC switching ratings: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. The AC motor rating is 1 hp at 230 V. Maximum mechanical service life is 30,000,000 operations. Maximum switching frequency varies by duty: 1,000 cycles/hour for AC-1, 750 cycles/hour for AC-2, AC-3, and AC-3e, and 250 cycles/hour for AC-4. Pick-up voltage is 0.8 of rated value, drop-out is 1.1 of full-scale value.

Environmental and Wiring

Accepts solid or stranded conductors from 0.5 to 4 mm², with multiple conductor options: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². Includes an auxiliary switch. Main contact size range is 20 to 12.

Frequently asked questions

What is the closest functional second-source for the 3RT2016-1BJ81?

The 3RT2016-1BB41-ZW97 is a listed peer variant. Both are Size S00 SIRIUS contactors with screw terminals; the key difference is the coil voltage — the 3RT2016-1BJ81 uses a 72 V DC coil, while the 3RT2016-1BB41-ZW97 uses a different coil voltage. Panel fit and wiring footprint are identical.

What is the depth of the 3RT2016-1BJ81?

The depth is 73 mm.

What conductor cross-section does the 3RT2016-1BJ81 accept?

It accepts solid or stranded conductors from 0.5 to 4 mm², and multiple conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm².

Will the 3RT2016-1BJ81 drop into a panel specified around the 3RT2016-1BB41-ZW97 without rewiring?

Yes, both are Size S00 SIRIUS contactors with the same screw-type terminals and DIN rail mounting footprint. The physical swap is direct; the only difference is the coil voltage — verify your control circuit voltage matches 72 V DC before substituting.

What compliance documentation does Siemens provide for the 3RT2016-1BJ81?

As a SIRIUS product, it typically carries CE, UL, CSA, and CCC certifications, with RoHS and REACH declarations available from Siemens. Specific documentation should be requested at time of order to match your compliance audit requirements.
