Product details

Rated 10 A at 24 V, it handles the typical PLC output or relay coil loads in a 24 VDC control loop; at 230 V the rating drops to 6 A, and at 400 V to 3 A, so the voltage derating curve matters when wiring across phases.

The S00 footprint — 45 mm wide, 57.5 mm tall, 72 mm deep — fits the standard SIRIUS grid; it occupies one 45 mm slot on the rail.

Wiring and contact ratings

Terminals accept solid conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm². At 110 V the contact current is 1 A; at 220 V it drops to 0.27 A, and at 500 V to 2 A — the non-linear derating reflects the arc extinction capability at higher voltages. Shock resistance is 10g / 5 ms and 5g / 10 ms, adequate for most industrial machinery but not for high-vibration mobile equipment without additional support.

Frequently asked questions

Where can I buy 3RH1140-1AP60 and how do I get a price?

This part is available to order through our independent distribution channel. Submit an RFQ for a current price and availability quote — we confirm both at quote time.

What is 3RH1140-1AP60's depth?

The depth is 72 mm.

What solid wire sizes does 3RH1140-1AP60 accept?

The terminals accept 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm² solid conductors.

Will 3RH1140-1AP60 drop into a panel specified around 3RH2440-1AP00 without rewiring?

No — the 3RH1140-1AP60 is size S00 (45 mm wide), while the 3RH2440-1AP00 belongs to a different size class. The mounting footprint and terminal layout are not identical; verify the panel cutout and wiring before substituting.
