Product Information
Extended Description
1SVR405622R6400 ABB: The CR-U048DC3LD 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 48 V DC rated control supply voltage and has a 3 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, and a diode, for surge suppression. Standard sockets, logic sockets, pluggable function modules, holders and markers are available as accessories.

FAQs
For DIN-rail installations, use CR-U compatible sockets and mount the relay directly onto a standard DIN rail. The device features robust circular pin terminals designed for quick insertion and reliable contact integrity. Ensure firm seating in the socket and verify alignment to prevent contact miswraps during cycling. This setup minimizes downtime during replacements and simplifies field service.
The relay operates with a 48 V DC rated control supply, provides 3 c/o SPDT contacts, and supports up to 250 V AC at 10 A for switching loads. Rated operational currents include AC-12 at 10 A (230 V) and DC-12 at 10 A (24 V). These specs enable multi-circuit control from a single input while maintaining coverage for common industrial control tasks.
The CR-U048DC3LD carries UL/CSA, CE, and UKCA declarations, along with VDE and other certifications for global compliance. These approvals ensure the relay meets safety, performance, and environmental requirements across US, European, and UK markets. For manufacturers, this simplifies regulatory submissions and supports referenceable compliance in design documentation.
Yes. The relay is rated IP40 and rated to operate from -40 to +70 °C, which supports use in many factory floors and equipment enclosures. It includes an integrated diode for surge suppression and an LED indicator for coil energization, improving diagnostics during commissioning and operation in environments with electrical noise or abrupt load changes.
The plug-in design reduces maintenance time by enabling fast replacements without rewiring, lowering downtime costs. The built-in diagnostics (LED) and surge protection extend component life and reduce failure rates. When deployed in scalable control architectures, it enables modular upgrades, improving asset utilization and delivering a favorable return on investment through higher uptime.
