The reusable packing ships in a pack of 88 units. The 5.5...8 A setting range covers small three-phase motors in the 2.2 to 4 kW ballpark at 400 V. The 1NO+1NC auxiliary gives you a feedback signal for the PLC and a hard-wired shutdown path; the NO side reports the relay state, the NC side breaks the contactor coil circuit on a trip. ## Deployment context Snaps onto the matching S0 contactor (3RT2 series) on a DIN rail inside the motor control center.","metaTitle":"Siemens 3RU1126-1HB0-ZW98 Overload Relay, 5.5-8 A, S0, Class","metaDescription":"Siemens 3RU1126-1HB0-ZW98 overload relay, 5.5-8 A, 1NO+1NC, Size S0, Class 10, for contactor mounting.
