3RT5044-1AN20 | Siemens Power Contactor

Description

Siemens 3RT5044-1AN20 Power Contactor is a 3-pole power contactor of size S3 with three normally open (3 NO) main contacts. This AC-operated unit provides a rated operational current of 65 A at 400 V in the AC-3 utilization category and operates with a control supply voltage of 220 V at 50/60 Hz. The device features screw-type terminals and is climate-proof according to IEC 60068 for universal use. It is a component of the modular SIRIUS system, allowing the attachment of auxiliary switch blocks and surge suppressors. The contactor maintains an IP20 protection class on the front according to IEC 60529 and provides a mechanical service life of 10 million operating cycles.
