ABB CR-U110DC3 Pluggable Interface Relay - 3c/o SPDT
Part Number: 1SVR405622R8000
Quick Summary
The ABB CR-U110DC3 pluggable interface relay is a universal SPDT switch module for DIN rail control. Users often face bulky, non-pluggable relays and inconsistent control voltages across multi-socket configurations. CE, UL/CSA, and UKCA certifications help ensure regulatory compliance in key markets while IP40 protection provides reliable operation in typical factory environments. The CR-U110DC3 integrates seamlessly with ABB CR-U sockets and accessories, delivering fast deployment, simplified maintenance, and scalable control in automated systems. With a 110 V DC control supply and three changeover contacts rated up to 250 V / 10 A, it supports reliable multiplexing of signals and loads. A built‑in test button and LED offer quick diagnostics during commissioning, reducing downtime and accelerating route to production.
Product Information
Extended Description
1SVR405622R8000 ABB: The CR-U110DC3 pluggable interface relay is a univeral relay and is also commonly referred to as an ice cube relay. CR-U relays may be plugged into CR-U sockets and this combination of relay and socket may be seemlessly snap-on mounted onto a DIN Rail. CR-U relays have robust circular pin terminals, designed and manufactured to handle tough, repetitive-use applications and are more durable than standard relays.This relay operates with a 110 V DC rated control supply voltage and has a 3 c/o (SPDT) output with contacts rated at 250 V / 10 A, enabling the possibility of switching multiple circuits with a single input signal. The relay has an integrated test button which is used for the manual actuation of the relay by locking it's output contacts. The test button facilitates easy testing and commissioning. The relay also has an integrated LED, which provides the visual indication of the energization of the relay coil. Standard sockets, logic sockets, pluggable function modules, holders and markers are available as accessories.

FAQs
Install the CR-U110DC3 into a compatible CR-U socket, then snap the assembly onto a standard DIN rail. Ensure the control voltage is 110 V DC and that the wiring uses proper gauge for 250 V AC loads up to 10 A. Verify the LED indicator confirms coil energization after commissioning.
The relay provides three SPDT contacts rated to 250 V AC at up to 10 A, with DC control of 110 V. For AC loads, ensure Ie ratings meet the application: AC-12 up to 230 V at 10 A, and consider the DC-13 ratings for mixed loads. Observe IP40 and temperature limits.
Yes, CR-U110DC3 is designed for 110 V DC control. Its limitations include DC-13 ratings of 24 V or 250 V load at lower current (2 A at 24 V, 0.1 A at 250 V). For high DC loads, verify load currents stay within rated Ie and avoid exceeding contact life expectations under continuous cycling.
The device supports CE and UKCA declarations, UL/CSA recognitions, and other standards such as RoHS compliance. These certifications streamline regulatory approvals for Europe, the UK, and North America, reducing compliance risk when designing automotive, industrial, or process control solutions.
Pluggable relays like CR-U110DC3 reduce downtime during maintenance by enabling quick swap-outs without rewiring. The integrated test button and LED speed commissioning, diagnostics, and troubleshooting, while the modular design lowers spare parts inventory and total cost of ownership over time.
