Siemens 3RT2016-2AP02 Spring-loaded contactor, 230V AC coil, 9A, 4kW

Product Positioning

The 3RT2016-2AP02 is a standard electromagnetic contactor from the Siemens SIRIUS 3RT2 series S00 frame. The main circuit features a 3-pole normally open contact, with a rated current of 9A and rated power of 4kW/400V AC-3. The control coil operates at 230V AC 50/60Hz and includes one normally closed (NC) auxiliary contact for interlocking or signal feedback. This model uses spring-loaded (push-in) terminals, allowing for quick and easy wiring without screws, making it particularly suitable for panel assembly, mass production, or control cabinets requiring frequent maintenance and replacement. It boasts a rated mechanical life of up to 30 million operations, an insulation voltage of 690V, a pulse withstand voltage of 6kV, and has obtained multiple international certifications including UL, CSA, CCC, KC, and EAC. It can be mounted on a standard 35mm DIN rail and is a reliable choice for direct starting control of small and medium-sized motors.

Core Product Advantages and Features

230V AC coil design

The control coil has a rated voltage of 230V and a frequency of 50/60Hz, which is universal and can be directly connected to common European standard control circuit power supplies. It has low holding power (approximately 27VA at 50Hz and approximately 24.3VA at 60Hz), saving on the load of the control transformer.

Spring-loaded quick-connect terminal blocks

Both the main circuit and the auxiliary circuit use spring-clamped terminals, which eliminates the need for screws during construction to crimp the wires, greatly reducing the wiring time for panel assembly and panel manufacturing lines, and also reducing the risk of screws coming loose.

1 set of normally closed auxiliary contacts

It has a built-in NC instantaneous auxiliary contact, AC-15 grade, which can carry 230V/10A or 400V/3A, making it convenient to connect to safety interlocking circuits or provide contactor status feedback signals.

High durability and multiple international safety certifications

With a nominal mechanical life of 30 million cycles, an insulation voltage of 690V, an impulse withstand voltage of 6kV, and international safety certifications such as UL, CSA, CCC, KC, and EAC, it is suitable for use in export-oriented machines.

Recommend

3RT2016-2BB44

Compared to versions in the same series that only have one set of auxiliary contacts, the 2BB44 provides four sets of auxiliary contacts (2NO + 2NC), which can simultaneously drive multiple interlocking or indicator circuits, reducing the cost of adding auxiliary contact sockets.

3RT2016-2AN21

The Siemens SIRIUS 3RT2016-2AN21 is a 3-pole electromagnetic contactor with an S00 frame. It features a 220V AC 50/60Hz coil with one set of normally open (NO) auxiliary contacts, spring-loaded terminals for screwless quick crimping, AC-3 rated 9A/4kW/400V, and IP20 protection rating.

3RT2016-2AF04

The Siemens SIRIUS 3RT2016-2AF04 uses a 110V AC 50/60Hz control coil, an S00 frame 3-pole contactor, and spring-loaded terminals for quick installation. It is rated AC-3 9A/4kW/400V and is suitable for control circuit configurations that require a large number of auxiliary contact combinations.
