Reliable AC-Controlled Switching for Industrial Equipment
Electromagnetic power relays such as the Finder 66.82.8.110.4300 operate by using an electrically energised coil to actuate a mechanical contact assembly. When the specified 110 V AC supply is applied to the coil, the electromagnetic mechanism closes the relay's two normally open contact circuits. When the coil supply is removed, the contacts return to their normally open state.
The Finder Series 66 is developed for electrical switching applications where dependable operation and substantial contact current capability are important. The two-pole normally open arrangement of the 66.82.8.110.4300 allows separate circuits or conductors to be switched together, providing a practical solution for industrial load control and automated equipment.
The relay is suitable for integration into appropriately designed electrical control systems, industrial machinery and OEM equipment. Correct contact ratings, electrical protection, conductor sizing, insulation requirements and thermal management must be considered when switching high-current, motor or inductive loads. The selected switching duty should remain within the manufacturer's specified operating limits.
Typical Applications
- Industrial machinery and automated production equipment.
- Electrical power switching and load control systems.
- Industrial heating and temperature regulation equipment.
- Heating, ventilation and air conditioning (HVAC) systems.
- Electrical control panels and power switching assemblies.
- Industrial process control and manufacturing machinery.
- Motor auxiliary switching circuits within the applicable contact ratings.
- Commercial and industrial electrical equipment.
- OEM machinery and automation control assemblies.
- Power management systems requiring two-pole normally open switching.

Frequently Asked Questions
What is the Finder 66.82.8.110.4300 used for?
The Finder 66.82.8.110.4300 is an electromagnetic power relay designed for electrical load switching in industrial machinery, automation equipment, heating systems and power control applications. Its two normally open contacts allow two electrical circuits to be switched simultaneously.
What is the coil voltage of the Finder 66.82.8.110.4300?
The relay features a 110 V AC nominal operating coil designed for compatible industrial alternating-current control supplies.
Does the Finder 66.82.8.110.4300 use an AC or DC coil?
The Finder 66.82.8.110.4300 uses an AC operating coil with a nominal voltage of 110 V AC. It is intended for an appropriate AC supply rather than direct connection to a DC control voltage.
What does 2 NO or DPST-NO mean?
2 NO (two normally open contacts), also described as DPST-NO (Double Pole Single Throw – Normally Open), means the relay has two separate contact circuits that remain open when the coil is not energised. Both circuits close when the relay coil is energised.
How does the Finder 66.82.8.110.4300 operate?
When the relay's 110 V AC coil is energised, its electromagnetic mechanism closes the two normally open contacts. When the coil supply is removed, the contacts return to their open positions, disconnecting the switched circuits.
Can the Finder 66.82.8.110.4300 be controlled by a PLC?
Yes. The relay can be integrated into a PLC-controlled system when a suitable interface supplies the required 110 V AC coil voltage. The PLC output or interposing control device must be rated for the relay's coil requirements.
Is this relay suitable for switching industrial electrical loads?
Yes. The Finder Series 66 is designed for industrial power switching applications. The permissible switching current and voltage depend on the specific contact ratings, electrical load category and operating conditions.
What is the difference between the Finder 66.82.8.110.4300 and 66.82.8.110.4003?
Both products belong to the Finder 66.82 relay family and use a 110 V AC coil. The 66.82.8.110.4300 is a two normally open contact variant, while the 66.82.8.110.4003 has a different product configuration suffix. Their complete contact diagrams and connection arrangements should be compared before substitution.
What should be checked before installing this relay?
Before installation, confirm the 110 V AC coil supply, two-pole contact arrangement, switching load ratings, terminal connections and applicable insulation and environmental requirements against the manufacturer's product specifications.
