Product Information
Extended Description
1SVR405621R0300 ABB: The CR-U012AC2L 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 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
CR-U012AC2L is designed as a pluggable relay for the CR-U socket family and is snap-on mounted to a DIN rail. This arrangement supports quick swaps without wiring changes, minimizes start-up time, and ensures secure, vibration-tolerant connections in control panels. For best results, ensure the socket is correctly seated and the DIN rail is clean and free of debris before mounting.
The device provides 2 c/o SPDT contacts with a contact rating of 250 V AC and up to 10 A. Control input is rated for 12 V AC, while output currents include AC-12 and DC-12/13 ratings depending on voltage. This makes it suitable for switching multiple circuits, with defined performance at 230 V AC and 24 V DC scenarios, subject to the respective Ie values.
This ABB CR-U series relay is documented with CE and UL/CSA certifications, can carry CAN/CSA approvals, and carries compliance declarations such as UKCA and VDE where applicable. It also aligns with IEC/EN standards referenced in the product data, supporting safe operation, testing, and global market access for control-relay installations.
The built-in LED indicates coil energization at a glance, enabling quick status checks during commissioning and field operation. The integrated test button allows manual actuation of the relay output, which helps verify circuitry, verify signal paths, and confirm correct contact behavior without applying external control signals. This accelerates setup and reduces commissioning risk.
The relay operates from -40 to +55 °C and has an IP40 protection rating, suitable for indoor industrial environments with moderate dust exposure. It is designed for a wide altitude range and can be used in typical factory floors, control cabinets, and similar panel environments. When selecting it, ensure ambient conditions stay within this range and consider enclosure protection for harsher environments.
