66.82.9.012.1303 Finder Power relay 2pole 30A DC 12V
Finder 66.82.9.012.1303 is a flange-mounted 30 A electromagnetic power relay featuring a 12 V DC coil, two normally open silver-nickel contacts, Faston 250 terminals and an ATEX / HazLoc special-version configuration for industrial electrical switching applications.
Why Choose the Finder 66.82.9.012.1303 Power Relay?
The Finder 66.82.9.012.1303 is a 30 A electromagnetic power relay designed for industrial electrical load switching, automation and power control applications. Featuring a 12 V DC operating coil, two normally open contacts (2 NO / DPST-NO) and silver-nickel (AgNi) contact material, this relay combines dependable switching performance with a robust industrial construction.
As part of the established Finder Series 66 power relay range, the 66.82.9.012.1303 features flange mounting and Faston 250 quick-connect terminals for installation into compatible electrical equipment. Its two normally open contact circuits operate together when the coil is energised, making it suitable for switching electrical loads through a common low-voltage control signal.
A distinguishing feature of the 66.82.9.012.1303 is its ATEX and HazLoc special-version designation, intended for suitably designed equipment used in specified hazardous-location environments. Its combination of 12 V DC control, 30 A nominal contact capability, reinforced coil-to-contact insulation and industrial mounting arrangement makes it a practical choice for OEM manufacturers and control system engineers requiring a specialised power relay.

Reliable DC-Controlled Switching for Industrial and Hazardous-Location Equipment
The Finder 66.82.9.012.1303 uses an electromagnetic coil to operate two normally open power contacts. When the specified 12 V DC supply is applied to the coil, the relay closes both switching circuits. Removing the coil supply allows the contacts to return to their normally open positions, disconnecting the controlled loads.
The relay's silver-nickel contact material provides a cadmium-free contact option within the Finder Series 66 range. Its flange-mounted design and Faston 250 terminals allow integration into industrial electrical equipment without requiring the relay itself to be soldered onto a PCB. Reinforced insulation between the coil and contacts helps maintain electrical separation between the control supply and switched circuits.
The ATEX / HazLoc special version is intended for equipment designed to satisfy the relevant hazardous-location requirements. The relay must be installed within an appropriate protective enclosure, and the complete assembly must comply with the applicable electrical, thermal and explosion-protection conditions. Its hazardous-location designation does not make the bare relay suitable for unrestricted installation in an explosive atmosphere.
Typical Applications

- Electrical load switching and power control systems.
- Industrial heating and temperature control equipment.
- Heating, ventilation and air conditioning (HVAC) equipment.
- OEM machinery using 12 V DC control circuits.
- Industrial process control and manufacturing systems.
- Power management and auxiliary switching assemblies.
- Electrical equipment designed for applicable ATEX Zone 2 environments.
- Control assemblies designed for applicable Class I, Division 2 hazardous locations.
- Flange-mounted relay applications requiring two normally open switching circuits.
