Finder 56.34.9.250.4000 – 56 Series Power relays

Finder 56.34.9.250.4000 – 12 A 4-Pole Changeover Industrial Power Relay

The Finder 56.34.9.250.4000 is a specified part number associated with the Finder 56 Series miniature industrial power relay range. The 56.34 relay platform features four changeover contacts (4 CO / 4PDT), a 12 A rated contact current and a plug-in connection arrangement designed for compatible Finder 96 Series sockets.

Finder 56 Series relays are widely suited to industrial automation, machinery control, electrical panels and building services equipment. Their electromechanical switching mechanism enables a control circuit to operate multiple electrically separate contact circuits, making the four-pole 56.34 configuration particularly useful for control, signalling, interlocking and auxiliary switching.

Important specification note: The exact 56.34.9.250.4000 variant could not be verified against the published Finder 56 Series coil tables. Although the 9 coil-code family denotes DC operation, the manufacturer's standard 56.34 DC coil range does not list a 250 V DC option. The 250 code must therefore not be treated as a confirmed 250 V DC coil rating without manufacturer verification. The technical information below distinguishes established 56.34 series specifications from characteristics requiring confirmation.

Key Advantages

• Four changeover contacts provide versatile switching for multiple control circuits.
• 12 A rated contact current across the standard Finder 56.34 relay platform.

• Plug-in construction facilitates relay replacement in compatible socket assemblies.
• Finder 96 Series socket compatibility provides flexible control panel installation options.
• 250 V AC rated contact voltage for the standard relay contact system.
• 400 V AC maximum switching voltage, subject to application requirements.
• Four mechanically linked changeover contact sets operated by one coil.
• Suitable for industrial automation, control cabinets and machinery interfaces.
• Established Finder 56 Series platform with socket and accessory options.

Four-Pole Changeover Switching for Industrial Automation

The Finder 56.34 relay platform provides four independent changeover contact sets operated by a common electromagnetic coil. Each pole contains a common terminal, a normally closed contact and a normally open contact. When the coil is energised, all four poles change state together; when the coil is de-energised, the contacts return to their normal positions.

This arrangement is particularly useful where a single control signal must operate several circuits simultaneously. Examples include machinery sequencing, control circuit changeover, auxiliary signalling and electrical interlocking. The four-pole design can reduce the need for multiple separate relays where the application permits common actuation.

The standard 12 A contact rating supports a broad range of appropriately rated industrial loads. However, permissible switching capacity varies with the electrical load. Inductive devices, motors, capacitive loads and DC circuits can impose different stresses on relay contacts, so the manufacturer's load ratings and application guidance must be followed.

For the requested 56.34.9.250.4000, the coil voltage and special configuration must be confirmed before installation. Applying a supply based solely on the 250 digits could damage the relay or prevent correct operation if the code does not represent a valid standard coil option.
