Product Information
Extended Description
1SVR405621R3100 ABB: The CR-U230AC2L 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 230 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
Install by snapping the CR-U plug-in relay into a matching CR-U socket mounted on a DIN rail. The relay features robust circular pin terminals and a front-facing LED for status indication. Ensure 230 V AC control supply is present and that the output contacts are connected to the intended loads. The integrated test button facilitates commissioning without extra test gear.
The unit operates on a 230 V AC control supply and provides 2 c/o SPDT contacts with an output rating of 250 V / 10 A. Rated operational currents are specified for AC-12 and AC-15 across voltage levels, making it suitable for switching multiple circuits from a single input signal in automation panels.
Yes. It supports operation from -40 to +55 °C and is rated IP40, allowing usage in typical industrial environments. It is designed for DIN-rail mounting with a compact footprint, enabling reliable performance without derating up to 2000 m altitude. Always confirm your specific load types and durations align with the ratings.
The CR-U relays include UL/CSA certification, CE marking, and UKCA where applicable, with additional VDE and UR marks supporting broader regulatory compliance. These certifications help meet global electrical safety and performance requirements, simplifying procurement for multi-region deployments.
The built-in test button allows manual actuation and commissioning without external tools, while the LED provides immediate energization feedback.
