Finder 66.22.8.208.0300 – 66 Series Power relays

Why Choose the Finder 66.22.8.208.0300 Power Relay?

The Finder 66.22.8.208.0300 is a high-performance 30 A electromechanical power relay designed for reliable switching of electrical loads in industrial automation, machinery control and power management systems. As part of the established Finder 66 Series power relay range, it combines high-current switching capability with reinforced insulation and a compact PCB-mounted construction suitable for industrial electrical equipment.

Featuring a 208 V AC operating coil and two normally open contacts (DPST-NO), the Finder 66.22.8.208.0300 allows two electrical circuits to be switched simultaneously using a common control signal. Its robust electromechanical design provides galvanic isolation between the operating coil and switching contacts, making it suitable for industrial control systems requiring dependable power switching.

With a 30 A rated contact current, 250 V AC rated switching voltage and 7,500 VA AC1 resistive switching capacity, this relay is suitable for demanding electrical applications. Its PCB mounting format with bifurcated solder terminals enables direct integration into printed circuit board assemblies used in industrial machinery, heating equipment and electrical control systems.

Reliable High-Current Switching for Industrial Automation

Electromechanical power relays such as the Finder 66.22.8.208.0300 enable electrical loads to be controlled using an independent operating circuit. When the 208 V AC coil is energised, the relay closes its two normally open contacts, allowing current to flow through the connected load circuits. When the coil is de-energised, the contacts return to their normally open position.

The Finder 66 Series is engineered for industrial applications requiring reliable high-current switching and electrical separation between control and power circuits. Its reinforced insulation, 8 mm creepage and clearance distances and high contact capacity make it a practical solution for industrial machinery, heating systems and electrical equipment.

The 66.22 PCB-mounted design is particularly suitable for OEM equipment manufacturers and industrial control system designers. Its bifurcated solder terminals support integration into appropriately designed printed circuit boards, while the two-pole normally open configuration provides flexible switching of electrical loads. Suitable PCB track dimensions, terminal connections and circuit protection must be provided for the intended load current.
