Why Choose the Finder 66.82.9.048.0300 Power Relay?
The Finder 66.82.9.048.0300 is a high-current electromagnetic power relay from the Finder 66 Series, designed for industrial automation, electrical control and power switching applications. Featuring a 48 V DC operating coil and two normally open contacts (DPST-NO / 2 Form A), it enables two electrical circuits to be switched simultaneously using a single control signal.
The Finder 66.82-0300 configuration provides a 30 A rated contact current and is designed for appropriately rated industrial electrical loads. Its normally open contacts close when the coil is energised and return to their open positions when the coil supply is removed.
With Faston 250 quick-connect terminals and a top flange mounting arrangement, the Finder 66.82.9.048.0300 is suitable for integration into compatible machinery, electrical equipment and industrial control assemblies. Its DC-operated electromagnetic design is particularly useful in systems employing a 48 V DC control supply.
Key Advantages
- 48 V DC operating coil for compatible industrial DC control circuits.
- Two normally open contacts enable simultaneous switching of two independent electrical circuits.
- 30 A rated contact current supports appropriately rated high-current switching duties.
- Faston 250 terminals provide convenient quick-connect electrical connections.
- Top flange mounting supports secure installation within electrical equipment.
- Monostable electromagnetic operation returns both contacts to their open positions when coil power is removed.
- 250 V AC rated contact voltage supports suitable industrial AC loads.
- 7500 VA rated AC1 switching capacity for resistive loads.
- Two-pole switching arrangement reduces the need for separate relays where two circuits must operate together.
- Part of the established Finder 66 Series industrial power relay range.

High-Current Two-Pole Switching with a 48 V DC Coil
The Finder 66.82.9.048.0300 uses a 48 V DC electromagnetic coil to operate two normally open power contacts. When the coil is energised, both contacts close, completing their respective electrical circuits. When the coil supply is removed, the relay's return mechanism opens both contacts.
This DPST-NO configuration enables two separate electrical loads or control circuits to respond to one switching command. The 30 A contact rating supports suitable industrial switching applications, provided that the connected loads remain within the manufacturer's specified ratings for voltage, current and utilisation category.
The relay's Faston 250 terminals and top flange mounting support integration into industrial equipment. For replacement applications, the coil voltage, contact configuration, mounting dimensions and electrical ratings should be checked against the existing relay and equipment requirements.
The 48 V DC coil rating describes the voltage required to operate the relay, not the voltage or current that its contacts can switch. DC load switching capacity must be evaluated separately from the relay's AC contact ratings.
Typical Applications
- Industrial automation and machinery control systems.
- Electrical control panels and switching assemblies.
- 48 V DC control circuits.
- High-current two-pole normally open switching.
- Industrial process control equipment.
- Machinery and auxiliary equipment interfaces.
- Electrical interlocking and equipment sequencing.
- Industrial heating and load control.
- Power distribution auxiliary control circuits.
- Maintenance and replacement of compatible Finder 66 Series relay installations.

Frequently Asked Questions
What is the Finder 66.82.9.048.0300 used for?
The Finder 66.82.9.048.0300 is an electromagnetic power relay designed to switch two normally open electrical circuits in industrial automation, machinery control and auxiliary power applications.
What coil voltage does the Finder 66.82.9.048.0300 require?
The relay has a 48 V DC nominal coil voltage. The applied control supply must match the manufacturer's specified DC coil operating requirements.
What contact arrangement does this relay have?
The relay has two normally open contacts (2 NO), described as a DPST-NO or 2 Form A configuration. Both contacts close when the coil is energised and open when it is de-energised.
What is the contact current rating?
The Finder 66.82-0300 configuration has a 30 A rated contact current. Actual switching capacity depends on the load voltage, electrical characteristics and applicable manufacturer ratings.
Is the Finder 66.82.9.048.0300 a changeover relay?
No. The .0300 configuration provides two normally open contacts rather than two changeover contacts. A DPDT relay should be selected where normally closed switching paths are also required.
What contact material does the Finder 66.82.9.048.0300 use?
The standard Finder 66.82-0300 configuration uses silver cadmium oxide (AgCdO) contact material, which is used in industrial power switching applications.
How is the Finder 66.82.9.048.0300 mounted?
The relay features a top flange / chassis mounting arrangement and Faston 250 quick-connect terminals for electrical connections.
What terminals does this relay use?
The relay uses Faston 250 quick-connect terminals measuring 6.3 × 0.8 mm, designed for use with appropriately sized mating connectors.
Is the Finder 66.82.9.048.0300 a latching relay?
No. It uses a monostable electromagnetic operating mechanism. Both normally open contacts return to their open positions when the coil is de-energised.
Can the Finder 66.82.9.048.0300 operate from a 48 V AC supply?
No. The .9.048 coil designation identifies a 48 V DC coil. An appropriately specified AC-coil relay is required for an AC control supply.
Can the Finder 66.82.9.048.0300 switch DC loads at 30 A?
Not automatically. The 30 A contact rating must be interpreted alongside the manufacturer's applicable load and voltage specifications. DC switching capacity can differ significantly from AC switching capacity.
