What is the 3RH1131-1AP00-ZW97?
It carries 3 normally open (NO) instantaneous contacts and no NC or delayed poles, so it is used purely to extend the I/O of a larger contactor or to build interlock logic in a panel. The coil is rated for both 50 Hz (0.8...1.1) and 60 Hz (0.85...1.1) at 230 V, meaning it works across the standard mains frequencies without a changeout — a single part covers both line frequencies common in export panels or dual-frequency plants.
The 3 NO contacts are rated for switching at various voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. These are thermal current ratings (AC-1 / resistive load curve); for motor or inductive loads, derate accordingly. The 6 kV surge voltage resistance (rated value) gives it basic impulse withstand for industrial panels with moderate transient exposure.
At 45 mm wide, 57.5 mm high, and 72 mm deep, it fits the standard S00 contactor footprint. Fastening is by screw or snap-on mounting onto DIN rail.
