3RT2015-1AN21

The coil operates at 220V AC, and the auxiliary contacts are a set of normally open (NO) contacts, suitable for extracting contactor operation status signals or driving indicator lights. The main circuit operates at 7A/3kW, and the S00 is compact in size.

Product Positioning

The 3RT2015-1AN21 and 1AN22 have the same coil voltage, 220V AC (50/60Hz). The difference lies in the auxiliary contact type: one set of normally open (NO). These are primarily used to retrieve contactor operating status signals, drive panel indicator lights, or input data to PLC digital input points, rather than for interlocking protection. The main circuit is also AC-3, 400V 7A/3kW, and AC-1 up to 18A. Belonging to the SIRIUS 3RT2015 S00 series, they are suitable for small to medium-sized three-phase motor control circuits. Screw terminal wiring allows for quick installation.

Core Product Advantages and Features

1 set of normally open (NO) auxiliary contacts feedback action status

It facilitates the extraction of contactor ON/OFF signals, connection of indicator lights, or input into the control system for monitoring.

220V AC coil, sharing the same voltage rating as 1AN22.

To facilitate the selection of normally open or normally closed auxiliary contact versions for viewing needs within the same panel.

7A/3kW main circuit capacity

The AC-3 has a rated current of 7A and a power output of 3kW at 400V, while the AC-1 can reach 18A. Both are suitable for small and medium-sized three-phase motors.

S00 compact design with screw terminals

With dimensions of only 57.5×45×73mm, both the main and auxiliary coil circuits use screw terminals, making maintenance and replacement convenient.
