The main circuit provides three normally open contacts and uses screw terminals in size S2, with a 690 V insulation rating and IP20 protection on the front (IP00 for the terminals). It supports operation across ambient temperatures from −25 °C to +60 °C and boasts up to 10,000,000 mechanical switching cycles; Siemens notes this model as phased-out and points to 3RT2027-1AK60 as its successor.
