66.82.9.024.0001 Finder Power relay 2pole 30A DC 24V

Why Choose the Finder 66.82.9.024.0001 Industrial Power Relay?

The Finder 66.82.9.024.0001 is a high-current 30 A, two-pole changeover (DPDT) industrial power relay designed for electrical switching, machinery control and industrial automation. Part of the established Finder 66 Series, this relay combines substantial switching capability with reinforced electrical insulation and a practical flange-mounted housing with Faston 250 quick-connect terminals.

Featuring a 24 V DC nominal operating coil and two independent changeover contacts, the Finder 66.82.9.024.0001 allows two electrical circuits to be controlled simultaneously. Each contact set provides normally open and normally closed switching paths, making the relay suitable for high-current switching, electrical interlocking, circuit changeover and auxiliary control functions.

The relay belongs to the 66.82 flange-mounted power relay family, which provides a 30 A normally open contact rating, a 250 V AC rated contact voltage and up to 7,500 VA AC1 switching capacity on normally open contacts. Its Faston 250 connections and reinforced coil-to-contact insulation support integration into industrial control panels, machinery and electrical power equipment.

High-Current Changeover Switching with Reinforced Insulation

The Finder 66.82.9.024.0001 operates through an electromagnetic coil energised by a 24 V DC control supply. When the coil is energised, its two changeover contact sets transfer from their normally closed positions to their normally open positions. When the coil is de-energised, the contacts return to their normal positions, providing conventional non-latching relay operation.

Its DPDT configuration provides two electrically independent changeover circuits. Each contact set includes a common terminal, a normally open terminal and a normally closed terminal. This arrangement supports switching between alternative electrical paths, providing auxiliary control signals and implementing electrical interlocks.

An important consideration is the difference between the relay's contact ratings. The normally open contacts are rated at 30 A, while the normally closed contacts are rated at 10 A. These ratings must be applied separately when designing electrical circuits, particularly where both contact positions carry substantial loads.

The 7,500 VA AC1 switching capacity on normally open contacts makes the Finder 66.82 family suitable for high-current resistive-load switching. For inductive loads, motors and DC circuits, the applicable utilisation-category and DC breaking-capacity ratings must be considered rather than relying solely on the nominal AC1 rating.

The relay incorporates reinforced insulation between the coil and contact circuits, including 8 mm creepage and clearance distances and a 6 kV impulse withstand rating. These characteristics support electrical separation between low-voltage control electronics and higher-voltage switched circuits when the relay is incorporated into appropriately designed equipment.

The 66.82 housing provides a flange-mounting arrangement and Faston 250 terminals for direct quick-connect wiring. This distinguishes the relay from the PCB-mounted 66.22 variants and supports installation in industrial control cabinets, machinery and electrical equipment.
