Siemens 3RT2015-2BM41 DC 220V coil contactor 7A 3kW

Product Positioning

The 3RT2015-2BM41 belongs to the SIRIUS 3RT2 series S00 frame contactor. Its main circuit specifications are consistent with other models in the same batch. It has an AC-3 rated current of 7A and can switch approximately 3kW three-phase motors at 400V. The coil voltage is DC 220V, which is not the most common 24V DC or 230V AC combination in Siemens' SIRIUS miniature contactor product line. It is more suitable for direct replacement of existing control panels that use 220V DC as the control power supply (such as some older relay logic panels or specific DC control systems), eliminating the need for additional step-down or rectifier conversion components. The order number has a digit of 2 in the 9th digit, uses spring clip terminal wiring, and has one set of normally open (NO) auxiliary contacts built into the main body. The manufacturer has publicly confirmed that this product complies with IEC 60947-4-1 general contactor standards and IEC 61508-2 functional safety specifications, and can operate stably in environments from -25°C to 60°C, adapting to the temperature conditions of most indoor distribution boxes in Taiwan.

Core Product Advantages and Features

Rare DC 220V coil specification

Compared to the commonly used 24V DC or 230V AC control voltage, the coil of this product is 220V DC, which is suitable for direct use in specific existing DC control circuits without the need for additional conversion circuits.

Spring clip terminal wiring

The 9th digit of the order number is 2. Both the main circuit and auxiliary contacts are spring-loaded terminals, requiring no screws for fastening.

Built-in 1 set of normally open auxiliary contacts

The main body integrates 1 NO auxiliary contact, which can directly obtain the action confirmation signal for use in the interlocking circuit.

Compliant with functional safety specifications

The product information indicates compliance with IEC 60947-4-1 and IEC 61508-2, and is suitable for reference in the design of control loops with safety requirements.
