66.82.8.230.1303 Finder Power relay 2pole 30A 230V

Why Choose the Finder 66.82.8.230.1303 Power Relay?

The Finder 66.82.8.230.1303 is a high-current 30 A electromagnetic power relay from the Finder Series 66 range, designed for dependable electrical load switching in industrial automation, machinery and power management equipment. Featuring a 230 V AC operating coil and DPST-NO (double-pole single-throw, normally open) contacts, it allows two electrical circuits to be switched simultaneously from a single control signal.

This model combines silver nickel (AgNi) contacts, reinforced electrical insulation and a robust electromechanical design. Its cadmium-free contact material provides a practical option for equipment manufacturers seeking reliable high-current switching, while the Series 66 construction offers substantial separation between the control coil and load contacts.

The 66.82.8.230.1303 is equipped with Faston 250 quick-connect terminals and a top-flange mounting arrangement for installation in industrial equipment and electrical enclosures. The special Ex nC hazardous-location variant makes it relevant to suitably designed and approved industrial installations, subject to the applicable certification and operating conditions.

High-Current Switching for Industrial and Hazardous-Location Control Systems

The Finder 66.82.8.230.1303 uses an electromagnetic coil to operate two normally open power contacts. When the 230 V AC coil is energised, both contacts close, allowing current to flow through their respective load circuits. When the coil supply is removed, the contacts return to their open positions. This provides straightforward control of two circuits using a single relay.

The DPST-NO arrangement is useful in applications where two electrical conductors or separate loads must be switched together. With a 30 A nominal current rating and 7,500 VA AC1 switching capacity, the relay is suitable for substantial resistive loads when operated within its specified electrical limits. Inductive, capacitive and motor loads require additional consideration because their switching characteristics can differ significantly from resistive loads.

The silver nickel contacts and reinforced coil-to-contact insulation contribute to dependable industrial operation. The Ex nC designation identifies a special hazardous-location version; however, installation in a classified area requires verification of the exact approval, temperature classification, permitted ratings and enclosure requirements against the relevant manufacturer documentation.

Its Faston 250 terminals and flange-mounted housing allow direct wiring and secure mounting in machinery and electrical panels. This distinguishes the Finder 66.82 configuration from PCB-mounted Series 66.22 models and makes it a practical choice where conventional wiring and chassis installation are preferred.
