Frequently Asked Questions
What is the Finder 62.33.8.400.4020 used for?
The Finder 62.33.8.400.4020 is an electromagnetic power relay designed for industrial electrical switching, machinery control and automation applications.
What coil voltage does the Finder 62.33.8.400.4020 require?
The relay requires a 400 V AC nominal coil supply from a compatible control circuit. This is the coil operating voltage, not the rated contact voltage.
What is the rated contact current of this relay?
The Finder 62.33 relay family has a 16 A rated contact current. The permissible current depends on the electrical load, switching voltage and operating conditions.
What does 3PDT mean on this Finder relay?
3PDT means Three Pole Double Throw. The relay provides three changeover contact sets, allowing three separate circuits to switch between normally closed and normally open connections.
Is the 400 V AC coil voltage the same as the contact voltage?
No. The 400 V AC coil rating specifies the supply required to operate the electromagnetic coil. The relay contacts have separate switching voltage and current ratings.
Can this relay be used in industrial automation panels?
Yes. The Finder 62 Series is designed for industrial electrical switching and can be incorporated into compatible automation and machinery control installations.
Can the Finder 62.33.8.400.4020 replace another Finder 62.33 relay?
Replacement suitability depends on matching the 400 V AC coil voltage, contact arrangement, switching ratings, connection method and complete product variant with the original relay.
