This Finder Installation Relay is designed for professionals in industrial and commercial electrical installations needing a compact and reliable switching solution. Its key benefit is its space-saving 17.4mm width and robust 20A switching capability, suitable for demanding applications. A potential caveat is the fixed 230VAC coil voltage, which must match the system's power supply.

The relay is rated for a maximum of 20A at 250VAC.
It features a single Normally Open (SPST-NO) contact configuration.
The coil voltage is 230VAC.
It is designed for mounting on a standard 35mm DIN rail.
AgSnO2 (Silver Tin Oxide) contact material offers increased resistance to contact welding and erosion, leading to enhanced reliability and a longer operational lifespan compared to standard silver contacts.
While primarily designed for AC, it might be used for DC loads with significant derating. Consult the datasheet for specific DC ratings and limitations.
The relay has a width of 17.4mm and a depth of 58.4mm.
Verify the coil is receiving the correct 230VAC supply. Check wiring connections to the coil terminals (A1/A2). Ensure the input voltage is within the operational range.
Check if the load current or voltage exceeds the relay's specifications (20A at 250VAC). Inspect contacts for signs of damage or contamination. If issues persist, the relay may need replacement.
Ensure the coil voltage is stable and within specifications. A fluctuating voltage can cause buzzing. Check for physical obstructions or damage.
Setup: Mount the relay securely onto a standard 35mm DIN rail. Ensure the coil voltage is precisely 230VAC. Connect the load and control circuits to the appropriate screw terminals, following the SPST-NO configuration. Verify all connections are tight before applying power.
Compatibility: This relay is designed for AC circuits with a 230VAC coil. It is compatible with industrial control systems using standard DIN rail mounting. The maximum switching power is 5 kVA (AC).
Care: Keep the relay clean and free from dust and moisture. Avoid exceeding the rated voltage or current specifications. Periodically check terminal connections for tightness. No user-serviceable parts are inside; replace the unit if damaged or malfunctioning.
