Product Positioning

Model 3RT2015-2AN22 and another model in the same batch, 3RT2015-2AN21, belong to the same AC 220V coil model group. Their main circuit specifications, coil voltage, and external dimensions are identical. The only difference is that, according to Siemens SIRIUS ordering code convention, the last two digits, 22, correspond to a built-in normally closed (NC) auxiliary contact, while 21 is normally open (NO). For the main circuit, this product has an AC-3 rated current of 7A and can switch to approximately 3kW three-phase motors at 400V. The 9th digit of the order number is 2, and it uses spring clip terminals, allowing for crimp-type quick wiring of both the main circuit and auxiliary contacts. The normally closed auxiliary contacts are particularly suitable for fail-safe interlocking protection circuit designs, such as simultaneously triggering an alarm or stopping other equipment when the motor stops abnormally. The manufacturer's publicly available information indicates that this product is made in Germany, weighs approximately 0.251 kg, and has a rated mechanical life of up to 30 million cycles.

Core Product Advantages and Features

The NO/NC corresponding model to 2AN21

The main circuit specifications, coil voltage, and external dimensions are the same; only the auxiliary contacts are distinguished as NO/NC according to the last digit of the order code, making it convenient to select them in pairs for specific projects.

Built-in 1 set of normally closed auxiliary contacts

The main body integrates 1 NC auxiliary contact, which is particularly suitable for interlocking protection circuits that break the circuit upon failure, such as synchronously triggering an alarm when there is an abnormal shutdown.

Spring clip terminal

The 9th digit of the order number is 2. Both the main circuit and the control circuit use crimp terminals, eliminating the need for screw fastening.

Made in Germany

The manufacturer's publicly available information indicates that the product is made in Germany, and the quality traceability is clear, making it suitable for project procurement where the place of origin is a requirement.
