Finder 66.22.9.006.0600 – 66 Series Power relays

Why Choose the Finder 66.22.9.006.0600 Industrial Power Relay?

The Finder 66.22.9.006.0600 is a high-current 30 A, two-pole normally open (DPST-NO) PCB-mounted power relay designed for industrial automation, electrical power switching and electronic control equipment. Part of the Finder 66 Series, this specialised relay combines substantial switching capacity with increased contact separation and reinforced insulation between its coil and contact circuits.

Featuring a 6 V DC nominal operating coil and two independent normally open contacts, the Finder 66.22.9.006.0600 allows two electrical circuits to be switched simultaneously from a single control signal. Its .0600 configuration provides normally open contacts with a separation greater than 1.5 mm, making it suitable for applications requiring increased contact-opening distance.

The relay provides a 30 A nominal contact rating, 250 V AC rated contact voltage and 7,500 VA AC1 switching capacity. With 440 V AC maximum switching voltage, reinforced coil-to-contact insulation and bifurcated PCB solder terminals, it is designed for integration into industrial machinery, power control assemblies and high-current electronic switching equipment.

High-Current Normally Open Switching with Increased Contact Separation

The Finder 66.22.9.006.0600 operates using an electromagnetic coil energised by a 6 V DC control supply. When the coil is energised, its two normally open contact sets close, allowing current to flow through the connected circuits. When the coil is de-energised, both contacts return to their open positions.

Unlike the standard Finder 66.22.9.006.0000, which has two changeover contacts, the 66.22.9.006.0600 has two normally open contacts only. This distinction is important when selecting a relay for an existing PCB or control circuit, because the two configurations provide different switching functions and must not be treated as directly interchangeable.

The .0600 contact configuration incorporates an open-contact gap greater than 1.5 mm. This increased separation is intended for applications requiring a larger physical distance between open contacts. Whether the relay provides an appropriate disconnection function depends on the applicable installation standards, overvoltage category and complete equipment design.

With a 30 A contact rating and 7,500 VA AC1 switching capacity, the relay supports high-current resistive-load switching. Its 250 V AC rated contact voltage and 440 V AC maximum switching voltage provide flexibility for appropriately rated electrical equipment. Inductive loads, motors and DC circuits must be assessed against the applicable load-specific ratings.

Reinforced insulation between the operating coil and contact circuits provides electrical separation between the low-voltage control system and the switched load. The relay's 8 mm creepage and clearance distances and 6 kV impulse withstand rating support integration into equipment requiring suitable insulation coordination.

The PCB-mounted construction uses bifurcated through-hole solder terminals for direct installation onto a printed circuit board. The PCB must be designed with suitable conductor dimensions, copper thickness, thermal management and electrical clearances for the intended current and operating environment.
