Releco PCB Power Relay 24V AC Coil 10A Switching Current 3PDT Plug-In MRC Series C3-A30X / AC 24 V

The Releco C3-A30X / AC 24 V is a high-performance PCB power relay engineered to offer precise switching capabilities in demanding industrial, automation, and control system applications. This model is part of the trusted MRC series, featuring a robust three-pole double throw (3PDT) contact configuration capable of handling switching currents up to 10A.

Fitted with a 24V AC coil, the relay is ideal for use in circuits requiring reliable actuation and isolation, including power distribution, signal conditioning, and automated system controls. The plug-in terminal design simplifies installation on PCB boards, ensuring secure connections and swift replacement or maintenance. The mechanical flag indicator and LED status indicator support easy monitoring of relay operation for troubleshooting and diagnostics.

Constructed using silver alloy contact material, the relay provides high conductivity and minimal contact resistance, contributing to durable performance and reduced maintenance requirements. Its operating temperature range from -40°C to 60°C enables deployment in environments with varying ambient conditions. The relay features a test button with color-coded dual function, allowing users to manually test or latch as needed, adding flexibility during commissioning or system checks.

The coil resistance of 67 ohms and coil power rating of 2.5 kW (as well as alternate ratings such as 2.2W from certain documents) deliver consistent actuation performance. The relay is certified to CSA, EN, IEC, RoHS, and UL standards, confirming adherence to safety and regulatory compliance for industrial usage. With dimensions of 66mm in height and 35mm in length, it easily integrates with PCB layouts and control panels.

Typical applications include industrial automation, laboratory machinery, manufacturing equipment, HVAC systems, and commercial installations where robust and precise switching is essential. This relay is commonly used in electrical panels, control cabinets, and signal circuits for reliable on-off control, alternative pathway switching, and system protection.
