Product Positioning

The 3RT2018-1AN22 also uses a 220V AC, 50/60Hz coil, but its auxiliary contacts are configured with one set of normally closed (NC) contacts. This, along with the 1AN21 (normally open) and 1AN24 (2NO+2NC) of the same voltage, forms a complete selection spectrum, facilitating the selection of the appropriate contact type based on the control logic. Normally closed contacts are often used to output feedback signals indicating "contactor not operating" or abnormal shutdown, connected in series in the PLC input or alarm circuit. The main circuit AC-3 rating is 7.5kW/400V, 16A, conforming to the S00 standard framework. It can share a mounting base with other thermal overload relays and auxiliary contact modules in the same series, making it a common choice for 220V control power supply environments.

Core Product Advantages and Features

220V AC coil, 1 set of normally closed contacts

Compared to the 220V coil model in the same series, this model has normally closed (NC) auxiliary contacts, which are suitable for feedback in abnormal/shutdown conditions.

Together with AN21 and AN24, they form a selection series.

Both are 220V coils, but their auxiliary contacts are 1NO, 1NC, and 2NO+2NC, respectively, which can be flexibly selected according to the control logic.

S00 frame, screw terminal wiring

It continues the common installation dimensions and wiring method of the SIRIUS 3RT20 series, which facilitates panel matching and spare parts management.

Compact size, weighing approximately 0.237 kg

The miniaturized design is suitable for control boxes or internal power distribution areas of machines with limited space.

3RT2018-1AN24

The 3RT2018-1AN24 features a 220V AC coil and four auxiliary contacts (2NO+2NC), making it more suitable for control panels requiring multiple interlocking signals than single-contact models in the same series. The AC-3 model is rated at 16A/7.5kW and weighs approximately 0.290 kg.

3RT2018-1AN21

The 3RT2018-1AN21 is driven by a 220V AC coil and is equipped with one set of normally open auxiliary contacts for operation status indication. It has an AC-3 rated capacity of 16A/7.5kW/400V, an S00 standard frame, screw terminals, and is compatible with IE3/IE4 motors.

3RT2018-1AF02

The 3RT2018-1AF02 coil has a voltage of 110V AC, a built-in set of normally closed auxiliary contacts, a mechanical life of 30 million cycles, an AC-3 electrical life of 10 million cycles, an AC-3 rated power of 16A/7.5kW, and a weight of approximately 0.232 kg.
