Product details

Auxiliary Contactor for Control Circuit Switching

The 10 A rating at 24 V is the thermal current (Ith) for the auxiliary contacts, governing the continuous current-carrying capacity in a control circuit. For inductive loads like contactor coils or relay coils, derate per the AC-15 or DC-13 duty cycles — the 230 V rating of 6 A and 400 V rating of 3 A reflect the switching capacity under those conditions. The 6 kV surge voltage resistance (rated impulse withstand voltage Uimp) ensures the contactor can handle transient overvoltages common in industrial control panels without flashover.

The contactor accepts solid conductors from 0.25 mm² to 2.5 mm² (2x per terminal), suiting standard control wiring.

Frequently asked questions

What is the closest functional second-source to 3RH1131-2AP00-ZW97?

The 3RH2422-1AB00 is a peer auxiliary contactor from the same SIRIUS family, but it is a different frame size (S2 vs S00) and contact configuration. It will not drop into a panel wired for the S00 footprint without rewiring the mounting and terminal layout. For a direct S00 replacement, stick with the 3RH1131 series.

What are the key ratings of 3RH1131-2AP00-ZW97?

It has 3 NO instantaneous contacts rated 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. Surge voltage resistance is 6 kV. Mechanical life is typical 30 million operations. Operating temperature range is -25 to +60 °C.

What compliance documentation does this part have?

The part is RoHS compliant per the substance prohibitance date of 07/01/2006. It carries IP20 front protection and pollution degree 3, meeting IEC/EN 60947-1 requirements. The surge voltage resistance of 6 kV aligns with overvoltage category III for industrial control panels.
