Legrand 042858 Safety Transformer 160VA 230-400V/24V

The Legrand 042858 safety transformer is a professional-grade electrical component engineered to provide reliable voltage conversion for demanding control circuits. With a power rating of 160VA, this unit efficiently transforms input voltages of 230V or 400V into a stable 24V output, ensuring consistent performance for low-voltage equipment in industrial and commercial environments.

Advantages

This safety transformer stands out due to its robust construction and high operational reliability. It is designed to maintain electrical isolation between the primary and secondary circuits, which is essential for enhancing safety in automation systems. The unit is built to withstand the rigors of continuous operation, providing a stable power supply that protects sensitive electronic components from voltage fluctuations and potential electrical hazards.

Suitable for

• Industrial control panels and automation systems
• Powering low-voltage relays and contactors
• Commercial building management systems
• Safety-critical control circuits requiring galvanic isolation

When it may not be suitable

This transformer is not intended for high-power applications exceeding its 160VA rating. It is also not suitable for direct connection to appliances requiring AC voltages other than 24V or for outdoor environments without appropriate protective enclosure housing.

Key specifications

• Power rating: 160VA
• Input voltage: 230V / 400V AC
• Output voltage: 24V AC
• Application: Safety and control circuits

How to use

Installation should be performed by a qualified electrician in accordance with local electrical regulations. The transformer is typically mounted within a control cabinet or distribution board. Ensure the input wires are connected to the appropriate primary terminals corresponding to your supply voltage (230V or 400V), and connect the secondary load to the 24V output terminals. Always verify that the total load does not exceed the 160VA capacity before energizing the circuit.

What to consider before purchase

• Verify that the 160VA power capacity is sufficient for your total connected load.
• Ensure the input voltage of your supply matches the 230V or 400V configuration.
• Check the available space in your control panel for proper mounting and heat dissipation.

Usage recommendations

For optimal longevity and safety, ensure the transformer is installed in a well-ventilated area within an enclosure to prevent overheating and protect against dust or moisture ingress. Periodically inspect all terminal connections to ensure they remain tight and free from corrosion.
