Product details

SIRIUS auxiliary contactor, size S00, 2 NO

The IP20 front protection means the contactor is safe against finger contact from the front, but requires enclosure for washdown or outdoor use.

Switching ratings and wire termination

The contactor switches the following currents at stated voltages: 10 A at 24 V, 1 A at 110 V, 0.27 A at 220 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. The rated control supply voltage is 230 V at both 50 Hz and 60 Hz, with an operating range of 0.8 to 1.1 times rated voltage at 50 Hz and 0.85 to 1.1 at 60 Hz. Terminals accept solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and 2x 4 mm². The 45 mm width and 72 mm depth fit standard S00 contactor footprints, and the mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, providing flexibility in dense panels.

Shock resistance is rated at 10g for 5 ms and 5g for 10 ms. The substance prohibitance date of July 1, 2006 indicates RoHS compliance from that date forward.

Sourcing and fit verification

For a BOM line requiring this exact order code, the active lifecycle and standard S00 footprint mean no substitution engineering is needed.

Frequently asked questions

What is the closest functional alternative to 3RH1122-1AP00-0TK0?

The 3RH2122-2AV00 is a peer in the SIRIUS family, but it carries different contact configurations and ratings; verify your control-circuit voltage and contact count against the 3RH1122-1AP00-0TK0's 2 NO contacts and 230 V rated control supply before substituting.

Where can I buy the 3RH1122-1AP00-0TK0 and how is it quoted?

This part is sourced through independent distribution and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time.

What compliance documentation does this contactor carry?

The substance prohibitance date of July 1, 2006 confirms RoHS compliance. The surge voltage resistance of 6 kV and pollution degree 3 indicate it meets IEC 60947-1 overvoltage and environmental classifications.

What are the key dimensions and mounting options?

Width is 45 mm, depth 72 mm, height 57.5 mm. Mounting is by screw or snap-on onto DIN rail, with ±180° rotation and ±22.5° tilt possible on a vertical surface.
