Product Positioning

The 3RT2016-2JB41 is the "J" coil version of the Siemens SIRIUS 3RT2016 family. Conrad's original specifications confirm that the control coil voltage is 24V DC, all three main contacts are normally open (NO), and it is equipped with one set of normally open (NO) auxiliary contacts, allowing direct connection to the motor operation indicator circuit or as a PLC input signal source. It boasts a mechanical life of 30 million operations, an IP20 protection rating, and an allowable operating temperature range of -25°C to +60°C, making it suitable for most indoor distribution boxes and server room environments in Taiwan. The terminals feature a spring-clamp design, supporting both snap-fit and screw-fixing methods for easy installation by personnel with different installation habits. The product has obtained RoHS and UKCA compliance declarations, meeting the compliance requirements for export to the UK and EU markets.

Core Product Advantages and Features

24V DC standard coil

The control voltage is 24V DC, suitable for general PLCs or DC 24V control circuits. It has three normally open main contacts for direct drive of a three-phase motor.

1 set of normally open auxiliary contacts

It can be used as a signal feedback source during operation or as a trigger source to link the next control loop, simplifying panel wiring logic.

Wide temperature range tolerance

Operating temperature range: -25°C to +60°C, suitable for harsh environments such as outdoor power distribution boxes and high-temperature computer rooms in Taiwan.

Dual-rail installation design

Supports both quick-release latches and screw-fixed installation methods, offering high installation flexibility and making maintenance and replacement more convenient.

3RT2016-2KB41

Like the 2KB42, the 2KB41 belongs to the Koppelschütz coupling contactor family. The difference is that the auxiliary contacts are a set of normally open ones. The coil is also designed for the electrical characteristics of PLC output, and it can be directly driven without the need for a relay.

3RT2016-2FB42

The F-shaped coil is 24V DC with a built-in suppression diode. It has 3 sets of normally open main contacts and 1 set of normally closed auxiliary contacts. The AC-3 rated value is 9A/4kW, and it is compatible with circuit breaker feedback or interlock protection circuits.

3RT2016-2FB41

The F-shaped coil is 24V DC and has a built-in suppression diode. It has 3 sets of main normally open contacts and 1 set of normally open auxiliary contacts. The S00 housing is compact and lightweight, making it suitable for distribution boxes with limited space.
