Product Information
Extended Description
1SVR405621R9100 ABB: The CR-U220DC2L 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 220 V DC 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 CR-U220DC2L is designed for plug-in use with CR-U sockets and snap-on DIN-rail mounting. It features robust circular pin terminals for reliable, vibration-resistant connections and easy field swaps without rewiring. This simplifies installation in densely packed panels and supports rapid replacement during maintenance cycles.
Coil voltage is 220 V DC, driving two changeover contacts (2 c/o SPDT). Output signals are rated up to 250 V AC at 10 A. DC-12 and DC-13 current ratings include (24 V) 10 A for DC-12 and (24 V) 2 A | (250 V) 0.1 A for DC-13, with AC-12 at 230 V rated at 10 A and AC-15 at 230 V rated at 1.5 A.
Yes, it is rated IP40 and operates from -40 to +70 °C, making it suitable for dry industrial cabinets and typical factory floors. Its design prioritizes reliability on DIN rails and within standard énclosures, though it should be mounted to avoid extended exposure to moisture or dust beyond IP40 protections.
The relay carries UL/CSA, CE and UKCA certifications, and is RoHS compliant. It is also documented with multiple declarations and certificates (CCC, CQC, EAC, UR, VDE) to support global deployments and regulatory audits.
A built-in test button and LED indicator streamline commissioning and troubleshooting, reducing downtime and on-site testing time. The plug-in design minimizes spare-parts inventory and speed of replacement, improving mean time between failures (MTBF) and lowering total cost of ownership in multi-unit automation installations.
