Siemens 3RT2016-2AB02 Spring-loaded Contactor, 24V AC Coil, Normally Closed Auxiliary Contact

Product Positioning

The 3RT2016-2AB02 is a 24V AC low-voltage coil specification in the Siemens SIRIUS 3RT2016 series. The main circuit features a 3-pole normally open contact, an AC-3 rated current of 9A, and a built-in normally closed (NC) momentary auxiliary contact, making it suitable for control circuits requiring power-off protection or fault interlock signals. Compared to the 220V/230V coil versions, the 24V AC coil can be directly used with the low-voltage output of the control transformer secondary side, improving operator and wiring safety. This product uses spring-clamped terminals, allowing for tool-free wiring of the main and auxiliary circuits. Weighing approximately 252.8 grams, with an insulation voltage of 690V, it can operate stably in environments ranging from -25°C to +60°C, and is suitable for machine safety circuits, emergency stop interlocks, and general motor control enclosures.

Core Product Advantages and Features

24V AC low voltage coil

The control coil is rated at 24V AC and can be directly connected to a control transformer for low-voltage output, reducing the risk of electric shock during operation and maintenance. It is commonly used in safety circuit designs.

1 set of normally closed auxiliary contacts

With a built-in 1 NC auxiliary contact and a rated current of 10A, it is suitable as a signal feedback element for power failure protection, fault interlocking, or safety circuits.

Spring-clamped terminal

Both the main circuit and the auxiliary circuit are spring-clamped, allowing for screwless wire crimping and speeding up panel assembly and subsequent repair and replacement.

Stable operation over a wide temperature range

It can withstand working environments from -25°C to +60°C, has an insulation voltage of 690V, and is adaptable to temperature and humidity changes in most indoor and outdoor control boxes.
