Product Positioning

The 3RT2015-2FB41 is one of the smallest S00 frame contactors in the SIRIUS 3RT2 series. Its main circuit has an AC-3 rated current of 7A and can switch approximately 3kW three-phase asynchronous motors under a 400V mains power. Unlike other DC coil models in the same batch, this product integrates a suppression diode (freewheeling diode) within the coil circuit. This absorbs back EMF surges when the coil is de-energized, reducing electrical impact on the PLC output module or nearby electronic control components. This built-in protection design is particularly practical for applications where the coil is directly driven by a PLC digital output point. The order number is 9-digit 2. It uses spring clip (screwless) terminals, allowing for quick crimp wiring of both the main circuit and control circuit. It has one built-in normally open (NO) auxiliary contact for direct operation confirmation signals. The measured net weight is approximately 0.314 kg. The front panel and terminal protection rating is IP20, and the mechanical life is rated at 30 million operations.

Core Product Advantages and Features

The coil has a built-in suppression diode.

The DC 24V operating coil circuit has integrated a suppression diode, which can absorb surge voltage at the moment of power failure, effectively reducing electrical interference to the PLC output point and surrounding electronic modules.

Spring clip terminal quick wiring

The spring terminal version with the 9th digit of the order number being 2 allows for wiring of the main circuit and control circuit without the need for a screwdriver, making it suitable for production lines with large-scale installations or those requiring frequent maintenance.

Built-in 1 set of normally open auxiliary contacts

The main unit integrates 1 NO auxiliary contact, eliminating the need to purchase an auxiliary contact module separately to obtain start confirmation or interlocking signals.

S00 Ultra-compact Body

With dimensions of only 70 x 45 x 73 mm and a net weight of approximately 0.314 kg, it is suitable for high-density arrangement of control boxes in limited space.

3RT2015-2FB42

Unlike the coupling contactor series, this model is classified as a general power contactor. It has a built-in diode and spring terminal in a 24V DC coil and is equipped with one set of normally closed (1NC) auxiliary contacts. It weighs approximately 0.314 kg.

3RT2015-2BM41

The SIRIUS S00 miniature contactor features an operating coil of the less common DC 220V specification, spring terminals, and a built-in 1NO auxiliary contact, making it suitable for direct use on existing 220V DC control circuit panels.

3RT2015-2BF42

The SIRIUS S00 series contactor has an operating coil of DC 110V and a spring terminal with a 1NC normally closed auxiliary contact, making it suitable for power distribution or interlocking circuits that use 110V DC as the control power supply.
