Product details

The 24 V DC coil pulls 3.3 W on pickup and holds at the same 3.3 W — steady-state dissipation that stays manageable inside a crowded enclosure.

The main contact path is rated 10 A at 24 V AC-12 (resistive), and for motor duty at 400 V it handles 4 kW in AC-2 (slip-ring motors) and 8.5 A in AC-4 (plugging/inching). Across higher voltages, the motor power ratings climb to 4.5 kW at 500 V and 5.5 kW at 690 V — so this one contactor covers 400 V through 690 V three-phase motor circuits within its thermal current envelope. The auxiliary contact block carries 2 instantaneous contacts, wired via the same spring-loaded terminal system as the main circuit.

Spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded copper, or 2x (24 to 14 AWG). The contactor is rated for side-by-side mounting with zero gap, keeping rail space tight — the body is 45 mm wide, 60 mm tall, and 114 mm deep.

Environmental limits and approvals

Operating temperature spans -25 to +60 °C, with a maximum operating altitude of 2 000 m and pollution degree 3 (conductive pollution, typical for industrial panels). The enclosure carries IP20 on the front and at the terminals — finger-safe but not washdown-rated, so it lives inside a sealed cabinet, not on the machine frame. Coil pickup is guaranteed at 85 % of rated voltage (20.4 V DC) and dropout below the holding threshold.

Frequently asked questions

Where can I buy 3RT1016-2BB44 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Submit a request for quote and you will receive current availability and pricing.

Will 3RT1016-2BB44 drop into a panel that was specified around 3RT1016-2AP02 without rewiring?

Both are SIRIUS S00 contactors on the same DIN-rail footprint, so the mechanical fit and rail spacing are identical. The difference is the coil voltage — 3RT1016-2BB44 uses a 24 V DC coil, while 3RT1016-2AP02 is an AC-coil variant. If the panel's control voltage is 24 V DC, the swap is straight; if the original was AC-powered, you will need to change the coil supply.

What is 3RT1016-2BB44's listed depth?

The depth is 114 mm, which together with the 45 mm width and 60 mm height defines the panel space needed.

What compliance documentation does Siemens provide for 3RT1016-2BB44?

The reference code per DIN EN 81346-2 is Q. Standard Siemens SIRIUS documentation includes the declaration of conformity, CE marking, and RoHS/REACH compliance data available through the Siemens Industry Online Support portal.
