Legrand 004741 Time Relay 1P 8A 12-230V AC/DC

The Legrand 004741 Time Relay is a professional-grade electrical component engineered for precise control of circuit switching operations. Designed for reliability and versatility, this 1P relay features an 8A switching capacity and operates across a broad voltage range of 12-230V AC/DC, making it compatible with diverse electrical installations. It provides a flexible timing range from 0.1 seconds up to 100 hours, allowing for accurate management of time-dependent processes in both residential and industrial environments.

Advantages

This time relay offers exceptional flexibility due to its wide supply voltage compatibility, which simplifies inventory management and installation across different systems. The device is built to handle a vast range of time intervals, ensuring it can be adapted to specific operational requirements from short-duration pulses to long-term cycles. Its compact design, occupying only one module, allows for efficient use of space within electrical distribution boards and control cabinets. The robust construction ensures consistent performance and longevity in demanding automation and lighting control applications.

Suitable for

• Automated lighting control systems
• Ventilation and fan delay-off circuits
• Industrial process automation
• Time-based switching in electrical distribution boards

When it may not be suitable

This relay is not intended for applications requiring high-current switching beyond its 8A capacity. It is also not suitable for environments where extreme moisture or corrosive gases are present, as it is designed for standard electrical enclosure installation.

Key specifications

• Configuration: 1P (Single Pole)
• Switching capacity: 8A
• Voltage range: 12-230V AC/DC
• Timing range: 0.1 seconds to 100 hours
• Module width: 1 module
• Weight: 86 g

How to use

The Legrand 004741 is designed for DIN-rail mounting within a standard electrical distribution board. Wiring should be performed by a qualified professional in accordance with local electrical regulations. The device functions by delaying the switch-off of a load, such as a ventilation fan. The timing cycle is initiated upon the opening of a non-illuminated switch or pushbutton connected to the control input. Once the pre-set time period has elapsed, the relay automatically switches the connected load to the OFF position.

What to consider before purchase

• Ensure the load current does not exceed 8A
• Verify that the control circuit uses non-illuminated switches
• Check available space in the distribution board for a 1-module device
• Confirm compatibility with your specific AC or DC voltage supply

Usage recommendations

For optimal performance and safety, ensure all connections are tightened securely and the device is protected from environmental contaminants. Regularly test the timing function during routine maintenance to ensure the relay continues to meet your operational requirements.
