3RT2015-1BN41

The 3RT2015-1BN41 is a unique model in the Siemens SIRIUS 3RT2 series S00 frame 3-pole power contactor: unlike most models in the same series that start with B and use DC coils, this model's coil voltage is actually verified to be 250V AC, and the control voltage Uc is also 250V, not a DC power supply. Special attention must be paid when purchasing and replacing spare parts to avoid using a DC power supply, which could cause the coil to fail to engage properly. It is equipped with one normally open (1NO) auxiliary contact, which can be used for status feedback or interlocking control. It has 3 main contacts, a rated current of 7A, and can handle a 3kW load under AC-3 conditions. The maximum operating voltage is 690V AC, making it suitable for some European applications or older control panels that still use 250V AC power, allowing direct use of the existing voltage level without the need for additional engineering work such as adding a transformer or changing the control power supply. Its S00 minimum frame and screw terminal design makes installation and maintenance simple.
