CR-P230AC2 relay: coil supply, contact arrangement and socket selection
ABB identifies CR-P230AC2 as a pluggable interface relay with a 230 V AC control supply and two changeover contacts. The product description gives a contact rating of 250 V/8 A. It can be used as a compact control-panel interface when the coil supply, contact duty and socket arrangement match the circuit. Verify the exact relay and socket combination before installation.

Application and engineering focus
Check the A1–A2 supply at the relay coil, including AC voltage tolerance and frequency. The coil rating is independent of the switched circuit voltage. Determine whether the two SPDT contact sets are used for interlocking, signal isolation or multiple loads, and check the load’s inrush, inductive suppression and switching category against the detailed datasheet. Do not interpret the maximum contact value as a rating for every load type.
Configuration, compatibility and related references
Choose a compatible CR-P socket, wiring terminal, retaining clip and marking accessory if required. Confirm panel dimensions, socket wiring and clearance before assembling a bank of relays. Similar CR-M and CR-P devices can differ in contact current, coil voltage, indicator or mechanical configuration. If a relay is plugged into an existing socket, verify pinout and part series rather than relying on footprint alone.

Installation and commissioning checks
De-energize both control and switched circuits before servicing. Inspect socket contacts, coil terminals and suppression components for heat or damage. After wiring, test pickup and dropout at the rated coil supply and verify each contact changes state as expected. Label the relay and socket to match the schematic, then document the load type and protective component used with inductive circuits.
During commissioning, verify the nameplate, configuration, wiring and diagnostics before enabling normal operation. Test the relevant signal path or protection response end to end under controlled conditions. Record settings and as-left measurements, and investigate abnormal values at the sensor, load, wiring or system configuration before replacing components.
Ordering, replacement and application information
For a quotation or replacement review, provide the complete designation 1SVR405601R3000 CR-P230AC2, ABB order code where available, serial or hardware revision, quantity, installation environment, connected equipment, interface requirements and target delivery date. Include a clear rating-label photograph and relevant wiring, loop or panel drawing when possible.
Ask the supplier to confirm the exact configuration, accessories, revision and any approved successor in writing. Do not select solely from a family name or product photograph. For safety, grid-protection, medium-voltage or regulated applications, obtain review by the responsible qualified engineer and follow local codes and the manufacturer’s instructions.
