Product Information
Extended Description
1SVR405621R7100 ABB: The CR-U110AC2L 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 AC rated control supply voltage and has a 2 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.

This relay operates from a 110 V AC control supply and provides two SPDT outputs rated up to 250 V AC at 10 A. It supports AC-12 and AC-15 ratings at 230 V and 24 V DC ratings of 10 A for DC-12, with DC-13 ratings of 2 A at 24 V or 0.1 A at 250 V. Suitable for signaling and interlocks in automation.
Yes. The CR-U family carries multiple certifications including CAN/CSA C22.2 No.14, UL 508, and CE, along with IEC/EN 61810-1 and 63000 standards. This broad certification footprint supports international deployment in control panels and safety-critical equipment, while RoHS compliance aligns with restricted substance requirements.
The relay family holds CE, UKCA, UL/CSA, UR, VDE, CCC, CQC, and EAC certifications, and is RoHS compliant under EU Directive 2011/65/EU. This comprehensive certification set helps with global compliance, traceability, and supplier audits, while the RoHS status assures restricted substances are within allowed limits.
The pluggable design enables fast field replacement without rewiring, reducing maintenance downtime. An integrated LED indicator and test button support quick commissioning and fault isolation, lowering MTTR. Compatibility with spare CR-U sockets streamlines inventory and procurement, delivering lower total cost of ownership for large DIN-rail control cabinets.
