Product details

It switches control signals and auxiliary loads in motor starter and contactor assemblies, extending the contact count of a main contactor or providing isolated feedback to a PLC. Mounts via screw or snap-on to a DIN rail, fitting the standard 45 mm width of the S00 frame.

Rated for 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — these are the thermal continuous currents the contacts can carry in their respective AC voltage classes. The 6 kV surge voltage resistance (rated impulse withstand) means the contactor can handle transient overvoltages common in industrial control panels without flashover. Shock resistance of 10g / 5 ms and 5g / 10 ms covers most vibration environments in fixed industrial equipment.

Terminals accept solid conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm². This covers standard control wiring up to 12 AWG. The 57.5 mm height and 111 mm depth fit within the S00 envelope, leaving room for adjacent devices on the same DIN rail. This allows installation in tight enclosures or non-standard panel layouts.

The 3RH1344-1AD00-ZX95 is a standard catalog item within the SIRIUS family. No official successor has been announced; the order code remains the active procurement reference for new builds and MRO spares.

Frequently asked questions

What are the key ratings for this auxiliary contactor?

It has 4 NO instantaneous contacts, rated 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V. Surge voltage resistance is 6 kV. Mechanical endurance is 10 million operations typical.

What wire sizes does the 3RH1344-1AD00-ZX95 accept?

Solid conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm² per terminal.

What is the mounting method and position flexibility?

Screw or snap-on mounting to DIN rail. Mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward.

What is the operating temperature range?

During operation: -25 °C to +60 °C. Storage and transport: -55 °C to +80 °C.
