Product details

It carries 2 normally-open and 2 normally-closed instantaneous contacts, with no leading, lagging, delayed, or make-before-break switching — a straightforward 2 NO + 2 NC block for standard interlocking or signaling. The coil is rated for 60 V DC, drawing 3.2 W during both closing and holding — no power drop-off once it's pulled in, so the coil supply stays loaded at 3.2 W continuously. That matters for DC-supply budgeting in a panel with multiple contactors.

The auxiliary contacts are rated by voltage: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. Those are thermal current ratings for the contact block — they tell you the maximum continuous current the contacts can carry at each voltage level. For a 24 V DC PLC output interposing relay, you've got 10 A headroom; at 230 V AC control voltage, you're limited to 6 A. The 1 A at 690 V rating is for high-voltage control circuits, not power switching. If you're switching dry contacts (PLC inputs, low-voltage signals), this contactor handles it without needing gold-plated contacts.

Wire capacity covers solid and stranded: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm² per terminal. For AWG: 2x 20–16, 2x 18–14, or 1x 12. That's enough for daisy-chaining control wiring through the contact block without pigtails.

Shock resistance is 10g for 5 ms and 5g for 10 ms — sufficient for normal industrial vibration but not rated for heavy impact near crushers or presses. RoHS compliance date is July 1, 2006 — the part is RoHS-compliant by the EU directive.

Frequently asked questions

What are the key contact ratings for this auxiliary contactor?

The contacts are rated 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. It has 2 NO and 2 NC instantaneous contacts.

What is the coil voltage and power consumption?

The coil is 60 V DC, consuming 3.2 W during both closing and holding.

What wire sizes does the 3RH1122-1BE40-0AA6 accept?

It accepts 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm² solid/stranded. AWG equivalents are 2x 20–16, 2x 18–14, or 1x 12.

Will the 3RH1122-1BE40-0AA6 fit alongside a 3RT1 contactor?

Yes. It's size S00 with a 45 mm width, matching the standard S00 contactor footprint. It mounts on DIN rail via screw or snap-on, so it clips directly beside a 3RT1 contactor without adapters.
