The Murrelektronik 6686351 is a single-phase control and isolation transformer designed for industrial automation and power supply systems. It is ideal for applications requiring electrical isolation and voltage conversion, offering a reliable solution for control cabinets. A key benefit is its compact size, making installation easier in space-constrained environments. However, users should note that specific voltage requirements beyond the standard 400V input and 230V output may require custom requests.

The Murrelektronik 6686351 is a control and isolation transformer. Its primary function is to step down the input voltage (400V AC) to a lower output voltage (230V AC) for control circuits, while also providing electrical isolation for safety and to prevent interference.
The transformer has a power rating of 250 VA (Volt-Amperes), which is the apparent power it can continuously supply to a load.
It features a built-in combination for screw-mounting rail attachment, allowing it to be easily installed on a standard DIN mounting rail within a control cabinet.
The transformer is equipped with spring clamp terminals, which facilitate quick, secure, and tool-free wire connections.
No, this transformer has an IP20 protection rating, meaning it is protected against solid objects larger than 12.5mm but offers no protection against water. It is designed for installation within protected control cabinets.
The product description mentions 'Other voltages on request,' indicating that custom voltage configurations may be available. You would need to contact the manufacturer or a distributor for specific options.
The transformer has an isolation class of T 40/B, which specifies its thermal and insulation characteristics for safe operation.
Verify that the 400V input power is correctly connected and present. Check the primary fuses or circuit breaker. Ensure all spring clamp terminals are securely fastened to the wires.
Check if the connected load exceeds the 250 VA rating. Ensure there is adequate ventilation around the transformer and that it is not installed in an excessively hot environment. Verify compliance with isolation class T 40/B requirements.
Inspect wiring connections for loose or damaged wires, especially at the spring clamp terminals. Ensure the wiring gauge is appropriate for the current draw. Check for vibrations that might be loosening connections.
Some hum is normal due to magnetic flux. However, excessive noise might indicate loose internal laminations or improper mounting. Ensure the transformer is securely mounted to the rail.
Setup: Ensure the transformer is mounted securely onto a standard mounting rail using its built-in attachment. Connect the primary side to the 400V AC power source and the secondary side to the 230V AC control circuit using appropriate wiring compatible with the spring clamp terminals. Verify all connections are secure before applying power.
Compatibility: This transformer is designed for single-phase AC power systems. It is compatible with standard control cabinet components and automation systems requiring a 400V input and providing a 230V output. Always ensure the load connected does not exceed the 250 VA rating.
Care: The transformer requires minimal maintenance. Keep the unit clean and free from dust and debris. Ensure adequate ventilation around the transformer to prevent overheating. Periodically check wiring connections for tightness and signs of wear. The unit is rated for isolation class T 40/B and protection class IP20, meaning it should be installed in a dry, protected environment.
