Siemens 3RH1131-1AK60 Contactor Relay 3NO+1NC 110/120VAC

The Siemens 3RH1131-1AK60 is a SIRIUS contactor relay in size S00. It provides electrically actuated switching through a 3NO+1NC contact arrangement with an AC control supply of 110 V at 50 Hz or 120 V at 60 Hz. The compact format and screw-terminal design support integration in industrial control panels and auxiliary control circuits.

- An AC control coil rated for 110 V at 50 Hz or 120 V at 60 Hz actuates the switching mechanism.
- Coil energization changes the state of three normally open contacts and one normally closed contact.
- Instantaneous auxiliary contacts support control logic, interlocking, and signal switching within the circuit.
- Screw-type terminals provide direct conductor termination for control and auxiliary wiring.

- 3NO+1NC auxiliary contact configuration with instantaneous switching elements.
- AC-15 operating current ratings of 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V.
- AC-12 operating current up to 10 A and DC-12/DC-13 current ratings as specified for 24 V, 110 V, and 220 V circuits.
- Size S00 housing with screw and snap-on mounting, front IP20 protection, and 57.5 mm x 45 mm x 72 mm dimensions.
- Insulation voltage rated at 690 V with 6 kV surge voltage resistance.

- Industrial control panels requiring electrically actuated auxiliary switching.
- Control circuits using mixed normally open and normally closed contact logic.
- Machine and panel builds using compact S00 contactor relay components.
