Four-Pole Switching for Industrial Automation and Control Systems

The Finder 56.34.8.400.0010 operates using an electromagnetic coil that controls four mechanically linked changeover contacts. When the specified 400 V AC control voltage is applied, the relay energises and transfers each common contact from its normally closed terminal to its normally open terminal. When the coil supply is removed, the contacts return to their original positions.

The 4 CO / 4PDT contact arrangement provides four separate changeover circuits operated by a common coil. This allows the relay to perform multiple control functions simultaneously, such as switching auxiliary equipment, distributing control signals or providing electrical status indications.

The relay's 12 A contact rating makes it suitable for a range of industrial switching applications, subject to the electrical characteristics of the connected loads. Its AgNi contact material offers dependable performance for conventional control duties, while the plug-in design supports straightforward maintenance and replacement.

Installation into a compatible Finder 96 Series socket provides a practical interface between the relay and the electrical panel wiring. Where DIN rail mounting is required, a suitable socket can be mounted onto a standard 35 mm DIN rail. The relay itself is a plug-in component and requires the appropriate mounting arrangement.

The 400 V AC coil supply must be distinguished from the contact switching voltage. The coil is designed for a compatible 400 V AC control circuit, while the contacts have a rated switching voltage of 250 V AC. The maximum switching voltage of 400 V AC must not be treated as the continuous rated switching voltage. Appropriate circuit protection, insulation and load selection are essential.
