Product Information
Extended Description
1SVR405621R3000 ABB: The CR-U230AC2 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. Standard sockets, logical sockets, pluggable function modules, holder and marker are available as accessories.

Pluggable CR-U concept keeps maintenance minimal and downtime predictable by letting the relay slide into CR-U sockets and snap onto a DIN rail, forming a compact ice cube relay package. The design supports modular expansion without rewiring, enabling quick swaps in busy cabinets. With 230 V AC control and two SPDT (c/o) contacts rated up to 250 V / 10 A, the unit can switch multiple circuits from a single input, reducing panel complexity. This capability supports machine control, protection schemes, and signaling in modern automation architectures. An integrated test button plus a coil-energized LED indicator accelerate commissioning and troubleshooting, letting technicians verify actuation without external instrumentation. This reduces debugging time and supports reliable start-up in regulated environments. Robust circular pin terminals and a durable housing are designed for high-cycle operation and vibration commonly found in industrial plants. The IP40 rating with operation from -40 to +55 °C and up to 2000 m altitude ensures dependable performance across a wide range of facilities. ABB provides a broad accessory ecosystem—standard sockets, logic sockets, pluggable function modules, holders and markers—so you can tailor the relay to your control scheme. Standardization reduces spare parts and simplifies procurement across projects. Compliance with major standards such as CAN/CSA C22.2 No.14, IEC/EN 63000, IEC/EN 61810-1, UL 508, CE, UL/CSA, UR, UKCA, VDE and RoHS ensures global applicability and risk mitigation. This supports procurement in regulated industries and multinational deployments.
