Product Information
Extended Description
1SVR405621R2000 ABB: The CR-U120AC2 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 120 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.

FAQs
The ABB CR-U 120AC2 relay is designed for quick DIN-rail installation by plugging the relay into a compatible CR-U socket and snapping the assembly onto the rail. Ensure the coil voltage matches 120 V AC, secure the socket, and verify the 2 c/o SPDT contacts are wired per your control schematic. Use the integrated test button to verify energization and use the LED indicator for feedback during commissioning. This modular approach minimizes wiring errors and speeds commissioning in control cabinets.
Key ratings include a rated control supply voltage of 120 V AC, rated operational voltage up to 250 V AC, and a contact rating of 250 V at 10 A for its 2 c/o SPDT outputs. The device supports 50/60 Hz operation, IP40 protection, and has detailed Ie ratings for AC and DC loads (AC-12 up to 10 A at 230 V, DC-12 up to 10 A at 24 V, and DC-13 up to 2 A at 24 V/0.1 A at 250 V).
The CR-U relay is designed for robust industrial use with IP40 protection and a broad certification footprint including CE, UL/CSA, UKCA, CCC, and RoHS compliance. While suitable for many automation tasks, confirm your specific safety profile and perform a risk assessment for critical safety functions. The relay’s modular, pluggable design supports rapid replacement and predictable performance in standard industrial environments.
This relay carries CE and UKCA declarations, UL/CSA certification, CCC and CCC Declaration, CQC and LR certificates, EAC, VDE, and RMRS where applicable. It is RoHS compliant and conforms to multiple standards including CAN/CSA C22.2 No. 14, IEC/EN 63000, IEC/EN 61810-1, and UL 508. Such a broad compliance portfolio simplifies procurement, auditing, and cross-border deployments.
The CR-U relay reduces downtime through a plug-and-play, field-replaceable design, lowering commissioning and maintenance times. The integrated test button and LED shorten diagnostics, while the modular sockets and DIN-rail mounting simplify stocking and retrofits. In turn, project timelines shrink and total cost of ownership improves due to fewer spare parts and faster qualification of new equipment.
