The insulation voltage is rated 1,000 V, and the pollution degree is 3 (conductive pollution typical in industrial enclosures), so the contactor is built for the dirty side of the panel, not just clean HVAC duty.","metaTitle":"Siemens 3RT5044-1AR60 SIRIUS Power Contactor, Size S3, 70 mm","metaDescription":"Siemens 3RT5044-1AR60 SIRIUS power contactor, size S3, 70 mm wide, 146 mm high, 139 mm deep.
