Part Number: 1SVR405621R4100
Quick Summary
ABB 1SVR405621R4100 is a pluggable interface relay for modular control in automation panels. Engineers often face wiring clutter and slow commissioning, which erodes efficiency. The CR-U series offers IP40 protection and CE/UKCA declarations, with UL/ CSA certifications for broader safety compliance. Its DIN rail snap-on mounting, integrated LED, and built-in test button simplify installation and commissioning. With a 12 V DC control coil and 2 c/o SPDT contacts rated up to 250 V/10 A, this solution scales from simple signaling to multi-circuit switching while preserving compact footprint and predictable behavior in harsh industrial environments.
Product Information
Extended Description
1SVR405621R4100 ABB: The CR-U012DC2L 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 12 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. Standard sockets, logical sockets, pluggable function modules, holder and marker are available as accessories.

FAQs
Install with compatible CR-U sockets, snap the relay onto a standard DIN rail, and confirm proper seating for the circular pin terminals. Check ambient temperature range (-40 to +70 C) and ensure adequate clearance for the LED indicator and test button. Use appropriate wire sizing for 10 A loads and keep wiring tidy to prevent interference.
The relay uses a 12 V DC coil and provides 2 c/o SPDT contacts with a 250 V AC switching capability at up to 10 A. It supports AC-12 ratings up to 230 V at 10 A and DC-12 ratings up to 24 V at 10 A, with DC-13 loads limited to 2 A at 24 V or 0.1 A at 250 V. Output is rated for 250 V / 10 A overall.
Yes. It carries CE and UKCA declarations of conformity, along with UL/CSA recognition (UL 508) and related certificates for the CR-U range. The device also meets CAN/CSA, IEC/EN 63000 and IEC/EN 61810-1 standards, supporting safe, compliant installation in global automation environments.
Its pluggable CR-U design enables rapid replacement and upgrades, reducing downtime. The DIN rail mounting, built-in LED, and test button streamline diagnostics, while the compact footprint and standardized sockets support scalable architectures. This is ideal for evolving control panels and systems where quick reconfiguration and predictable performance matter.
Plan for field-life replacement via plug-in modules and sockets, keeping spare CR-U relays and sockets available. The device operates from -40 to +70 C and up to 2000 m altitude without derating, with IP40 protection. Ensure compatibility with UL/CSA and CE/UKCA requirements, and schedule periodic checks of connections to prevent oxidation or loosening in vibration-heavy applications.
