Product Positioning

The 3RT2015-1BM41 is a Siemens SIRIUS 3RT2 series S00 frame 3-pole power contactor. It features a 220V DC coil design and an operating voltage range of approximately 0.8 to 1.1 times its rated value. It is commonly used in generator start-up control, substation DC operating power supplies, uninterruptible power systems (UPS), or industrial circuits powered by 220V DC battery banks. One normally open (1NO) auxiliary contact provides immediate feedback on the main contact's closing status, serving as an operation indicator, counter, or start-up interlock signal. The main contacts are 3-pole with a rated current of 7A. Under AC-3 conditions, it can load a 3kW/400V motor, with a maximum withstand voltage of 690V AC. Its mechanical life is typically up to 30 million operations, and its electrical life (AC-3, derating conditions) is approximately 200,000 operations. With its compact S00 minimum frame and screw terminal design, it is suitable for installation and maintenance in space-constrained DC control panels.

Core Product Advantages and Features

220V DC high voltage coil

The operating voltage range is 0.8 to 1.1 times the rated value, suitable for 220V DC operating power supply systems such as generator sets and substations.

1 set of normally open auxiliary contact feedback

It can be used as an operation indicator, counter, or interlock start signal, simplifying the wiring design of the control panel.

Mechanical life up to 30 million cycles

The highly durable design reduces the frequency of maintenance and replacement in situations requiring frequent operation.

Main contact 3 poles 7A/3kW

Meets AC-3 specifications and is sufficient to directly start small three-phase motors and general pump and fan loads.
