Siemens 3RT2015-2BB44-3MA0 24V DC coil contactor AC-3 7A/3kW

Product Positioning

The 3RT2015 is the smallest S00 model in the Siemens SIRIUS 3RT2 series with a main circuit rating of only 7A and approximately 3kW at 400V. Compared to the similarly sized 3RT2016 (9A/4kW), it is more suitable for smaller motors or auxiliary circuit applications. The 3RT2015-2BB44-3MA0 uses a 24V DC coil drive and is equipped with two sets of auxiliary contacts. The "-3MA0" at the end of the model number is a Siemens factory optional code; for actual details (such as terminal crimping methods or special verification versions), it is recommended to refer to the original manufacturer's specifications. Kenxin Motors provides selection and stock availability services for this small contactor.

Core Product Advantages and Features

SIRIUS Series Minimum Main Circuit Rating

The AC-3 has a capacity of only 7A/3kW, making it the smallest load capacity model in the S00 size, suitable for simplified circuit designs.

24V DC coil drive

The coil is powered by 24V DC and is commonly used in PLC output direct drive or battery-powered control systems.

2 sets of auxiliary contact configuration

Compared to models with only auxiliary contacts, it can provide both signal feedback and interlocking control functions simultaneously.

Factory optional code version

The model number ending in "-3MA0" is a specific factory option. Kenshin Motors can assist in confirming the actual specifications.
