Product Positioning

The 3RT2015-2AP02 is a SIRIUS 3RT2 series S00 frame contactor. Its operating coil is AC 230V, and it supports both 50Hz and 60Hz power frequencies, making it suitable for applications where the power supply is directly drawn from a 230V single-phase grid, eliminating the need for a separate 24V transformer and rectifier module. The main circuit AC-3 has a rated current of 7A, capable of switching approximately 3kW three-phase motors under a 400V grid, while AC-4 has a rated current of approximately 6.5A. The 9th digit of the order number is 2, indicating the use of spring-clamp terminals for quick crimp wiring in both the main circuit and control circuit. The last two digits of the order number, 02, correspond to a built-in normally closed (NC) auxiliary contact, suitable for use as interlocking protection, fault warning, and other failure-based circuit breaking logic. The auxiliary contact also features low-load signal switching capability, with the manufacturer's data indicating a failure rate of less than 1 in 100 million (under 17V, 1mA low-potential signal conditions), making it suitable for use with low-potential signal circuits such as PLC input cards.

Core Product Advantages and Features

AC 230V dual-frequency coil

It supports both 50Hz and 60Hz power supplies and can directly use the existing 230V single-phase control power supply on site without the need for additional transformer and rectifier modules.

Built-in 1 set of normally closed auxiliary contacts

As indicated by the last digit of the order code 02, the main body integrates 1 NC auxiliary contact, which is suitable as a source of interlock protection and failure-based open circuit warning signal.

High reliability during low load switching

The auxiliary contacts have a failure rate of less than 1 in 100 million under a low potential signal of 17V/1mA, making them suitable for use with sensitive signal circuits such as PLC input cards.

Spring clip terminal

The 9th digit of the order number is 2. Both the main circuit and auxiliary contacts can be crimped for quick wiring, eliminating the need for screw fastening.
