Finder 66.22.8.208.1300 – 66 Series Power relays

Why Choose the Finder 66.22.8.208.1300 Power Relay?

The Finder 66.22.8.208.1300 is a PCB-mounted electromagnetic power relay from the Finder 66 Series, designed for industrial power switching, machinery control and commercial electrical equipment. Its ordering code indicates an AC-operated coil, a two normally open (2 NO / DPST-NO) contact arrangement and silver nickel (AgNi) contact material. The 208 voltage designation should be confirmed against Finder's exact-part documentation before the coil supply is specified.

Built around the established 66.22 power relay platform, this model offers two independent normally open switching circuits operated by a single electromagnetic coil. Its direct printed circuit board (PCB) mounting and bifurcated solder terminals make it suitable for OEM electronic assemblies, industrial control boards and equipment where reliable electrical switching must be incorporated into a compact PCB layout.

The standard Finder 66 Series provides a 30 A normally open contact platform, a 250 V AC rated contact voltage and reinforced insulation between the coil and contacts. These characteristics make the 66.22 family useful for heating systems, industrial appliances and automation equipment. As the 66.22.8.208.1300 is a less commonly documented coil variant, its exact coil voltage, operating range and applicable certifications should be checked against the manufacturer's product-specific information before installation.

Technical verification note: The Finder 66 Series documentation identifies the standard AC coil voltages and the contact material and contact circuit ordering codes. However, the exact 8.208 coil specification was not independently confirmed in the available series tables. The nominal coil voltage, operating limits and variant-specific electrical ratings should therefore be verified with Finder before the relay is selected or energised. General series ratings must not be treated as guaranteed specifications for an unverified variant.

Reliable Dual-Pole Switching for Industrial AC Control Systems

The Finder 66.22.8.208.1300 uses an electromagnetic coil to operate two normally open contact circuits. When the correct AC coil supply is applied, both contacts close and allow current to flow through their respective electrical loads. When the coil is de-energised, the spring-return mechanism restores the contacts to their normally open positions, interrupting both circuits.

Its DPST-NO contact arrangement is particularly useful where two separate circuits need to be switched together without requiring normally closed terminals. The AgNi contact material distinguishes this model from Finder 66 Series versions fitted with standard AgSnO₂ contacts. Because contact materials can have different switching characteristics, especially for loads with high inrush currents, the actual electrical load should be assessed against the appropriate manufacturer's ratings.

The relay's reinforced coil-to-contact insulation supports electrical separation between the control circuit and switched power circuits. Direct PCB mounting also allows integration into compact equipment designs. For reliable operation, the finished assembly must provide suitable copper conductor dimensions, solder joint capacity, electrical clearances, thermal management and appropriate circuit protection. The coil supply must match the exact 208 variant specification rather than being assumed interchangeable with a standard 230 V AC relay.
