Product details

The coil is rated for 36 V AC at both 50 Hz and 60 Hz, with an apparent pick-up power of 37 VA and a holding power of 5.7 VA at an inductive power factor of 0.8. Rated operational currents vary by voltage: 10 A at 230 V, 6 A at 24 V, 3 A at 110 V and 400 V, 1.2 A at 220 V, and 1 A at 690 V. The maximum operating frequency is 10,000 switching cycles per hour for both AC and DC loads, with DC-12 and DC-13 duty limited to 1,000 cycles per hour.

Screw terminals accept solid or stranded conductors: 2× (0.5 to 1.5 mm²), 2× (0.75 to 2.5 mm²), or 2× 4 mm². For AWG, the range is 2× (20 to 16), 2× (18 to 14), or 2× 12. Finely stranded wire with core-end processing uses the same cross-sections. Dimensions are 57.5 mm high, 45 mm wide, and 73 mm deep — a compact S00 footprint that fits standard DIN-rail enclosures.

Frequently asked questions

Does 3RH6122-1AG00 include screw terminals?

Yes, it has screw terminals accepting solid, stranded, and finely stranded conductors up to 2× 4 mm² or 2× 12 AWG.

What is the mounting method for 3RH6122-1AG00?

It mounts via screw and snap-on onto 35 mm DIN rail, with ±180° rotation and ±22.5° tilt possible on a vertical surface.

What is the difference between 3RH6122-1AG00 and 3RH6122-1BG00?

The 3RH6122-1AG00 has a 36 V AC coil, while the 1BG00 variant uses a different coil voltage. All other mechanical and contact ratings are identical as they share the same S00 contactor relay platform.
