Terminal screws take a Pozidriv PZ2 tip with a 5–6 mm shaft diameter. The auxiliary switch is integrated into the relay body, with M3 screw terminals for the main contacts.","metaTitle":"Siemens 3RU2116-4AB1 SIRIUS Thermal Overload Relay, Class 10","metaDescription":"Siemens 3RU2116-4AB1 SIRIUS thermal overload relay, size S00, Class 10 trip, 16 A at 480/600 V, 7.5 kW at 400/500 V.
