Releco Power Relay 24V DC Coil 5A Switching Current DPDT C9-R21N

Releco C9-R21N power relay is a high-performance industrial-grade component featuring a 24V DC coil and a double-pole double-throw (DPDT) contact configuration. It operates with a 5A switching current and is designed for reliable and efficient bi-stable switching that retains the current switched state irrespective of the excitation.

This plug-in type miniature remanence relay includes a gold-plated contact material that ensures low contact resistance and long-term durability, ideal for demanding electrical applications in automation and control systems. The coil draws a power of 1.2W with a resistance of 50 ohms, enabling optimized energy use.

The relay’s mechanical design incorporates a mechanical flag indicator and a test button feature, although the test button is currently replaced by a black blanking plug. The compact dimensions of 21mm length, 28mm width, and 37.5mm height make it space-saving and convenient for installation.

Operating temperature range of -40°C to 60°C ensures its suitability for extreme conditions in industrial, HVAC, and commercial equipment sectors. Its switching power capacity is rated at 600 kVA with a maximum switching AC voltage of 120V, making it robust for many electrical systems.

Typical applications include anti-condensation equipment, car washing machines, coffee makers, commercial cooking devices, dryers, pumps, refrigeration equipment, and industrial cleaning machinery. This relay is compliant with various international standards including CSA, EN, IEC, RoHS, UL, CCC, CE, cRUus, cULus, and EAC certifications.

Manufactured in China, the C9-R21N relay stands out for its reliable performance and versatile industrial use, making it an essential component for installation engineering requiring efficient switching solutions.

This relay is a miniature remanence type with two changeover contacts ensuring bi-stable switching. The coil voltage rating is 24V DC with a coil resistance of 50 ohms. It supports switching AC voltage up to 120V with a power rating of 600 kVA.
