66.22.8.120.1301 Finder Power relay 2pole 30A 120/125V

Why Choose the Finder 66.22.8.120.1301 Power Relay?

The Finder 66.22.8.120.1301 is a heavy-duty electromagnetic power relay from the Finder 66 Series, designed for dependable switching in industrial automation, machinery control and commercial electrical equipment. Featuring a 120 V AC nominal coil and a two-pole normally open (2 NO / DPST-NO) contact arrangement, it enables a single control signal to switch two independent electrical circuits simultaneously.

Designed for direct printed circuit board (PCB) mounting, the Finder 66.22.8.120.1301 provides a practical switching solution for OEM equipment manufacturers and industrial control system designers. Its bifurcated solder terminals support secure PCB installation, while the two normally open contact sets are suited to applications requiring coordinated load energisation without changeover switching.

The Finder 66 Series is recognised for its 30 A power relay platform, robust electromagnetic construction and reinforced insulation between the coil and contacts. The 66.22.8.120.1301 belongs to the 66.22 PCB-mounted relay family, with a nominal coil consumption of 3.6 VA at 50 Hz. For this exact suffix, the contact material, enclosure sealing classification and variant-specific ratings should be confirmed against the manufacturer's ordering documentation before final equipment approval.

Specification note: The published Finder 66 Series technical data establishes the general characteristics of the relay family, but the complete ordering configuration for 66.22.8.120.1301 could not be independently verified. Contact material, enclosure classification and exact variant-specific ratings should therefore be checked against the manufacturer's confirmation before being used as guaranteed design specifications.

Reliable Dual-Pole Power Switching with 120 V AC Control

The Finder 66.22.8.120.1301 uses a 120 V AC electromagnetic coil to operate two normally open contact sets. When the coil receives its rated AC supply, the relay mechanism closes both contacts, allowing current to flow through their respective electrical circuits. When the coil is de-energised, the spring-return mechanism restores both contacts to their normally open positions.

This DPST-NO switching arrangement is useful where two separate loads or supply conductors must be controlled by a single command. Unlike a DPDT changeover relay, the normally open configuration does not provide alternative normally closed switching paths. It is therefore particularly appropriate for straightforward load energisation, equipment enable functions and coordinated switching duties.

The reinforced insulation system separates the AC coil from the power contacts, supporting industrial equipment designs that require electrical isolation between the control supply and switched loads. As with all PCB-mounted power relays, the final assembly must provide suitable PCB conductor dimensions, solder joint capacity, thermal management, electrical clearances and protective devices. Inductive or high-inrush loads may require additional contact protection and careful assessment against the manufacturer's switching curves.
