56.34.8.230.4010 Finder Miniature power relay 4 pole 12A 230V

Why Choose the Finder 56.34.8.230.4010 Industrial Power Relay?

The Finder 56.34.8.230.4010 is a miniature industrial power relay featuring a 230 V AC coil, four changeover contacts (4 CO / 4PDT) and a 12 A rated contact current. Part of the Finder 56 Series, this plug-in electromechanical relay is designed for industrial automation, electrical control panels, machinery and multi-circuit switching applications.

A key feature of this model is its silver tin oxide (AgSnO2) contact material, which is suited to applications involving demanding switching conditions and certain loads with elevated inrush currents. The relay also incorporates a lockable test button, providing a convenient way to check mechanical contact operation during appropriate commissioning and maintenance procedures.

With a 250 V AC rated contact voltage, 3,000 VA AC1 switching capacity and compatibility with selected Finder 96 Series sockets, the Finder 56.34.8.230.4010 provides a practical solution for switching several electrical circuits from one AC control signal.

Technical note: The exact product configuration is identified as a 230 V AC, 4PDT, 12 A relay with AgSnO2 contacts. The 4010 suffix identifies the silver tin oxide contact version with a lockable test button. Certain electrical endurance, insulation and coil characteristics listed above are Finder 56.34 family specifications; final equipment designs should be checked against the current manufacturer's datasheet and the ratings of the selected socket.

Silver Tin Oxide Contacts for Demanding Switching Applications

The Finder 56.34.8.230.4010 uses AgSnO2 (silver tin oxide) contacts rather than the standard AgNi contact material found in many general-purpose Finder 56 Series relays.

Silver tin oxide is commonly selected for its resistance to contact welding and erosion under certain demanding switching conditions. This makes it relevant to applications involving electrical loads with significant inrush currents, provided the specific load remains within the relay's published ratings.

The relay provides a 12 A rated contact current and 3,000 VA AC1 switching capacity. These ratings must not be interpreted as universal limits for every load type. Motors, transformers, capacitive loads and lighting circuits can impose switching stresses that require additional assessment or derating.

Four Changeover Contacts for Flexible Control

With its 4 CO / 4PDT arrangement, the Finder 56.34.8.230.4010 contains four separate changeover contact sets operated by one electromagnetic coil.

Each contact set includes a common terminal, a normally closed connection and a normally open connection. Energising the 230 V AC coil transfers all four contacts to their operated positions. When the coil is de-energised, the contacts return to their normal positions.

This arrangement is useful for equipment requiring several switching or signalling functions from one control input, such as machinery sequencing, auxiliary control, status indication and electrical interlocking.

Plug-In Mounting and Lockable Test Button

The Finder 56.34.8.230.4010 uses a plug-in mounting arrangement designed for compatible Finder 96 Series relay sockets. This allows the relay to be installed and replaced without disturbing the permanent wiring connected to the socket.

The integrated lockable test button provides a means of manually operating the relay during appropriate functional checks. It is particularly useful during commissioning and troubleshooting, although manual actuation must only be performed when the connected equipment can be operated safely.

For installations requiring a flange-mounted connection arrangement, Finder also offers compatible mounting accessories within the 56 Series ecosystem. The selected socket or adaptor should be checked for the correct four-pole configuration, electrical ratings and physical compatibility.
