Schneider Electric 56173 Residual Current Relay with Manual Reset 0.03-30A 240V

The Schneider Electric 56173 is a professional residual current relay engineered for high-precision electrical circuit protection in demanding environments. This device provides comprehensive monitoring of leakage currents, ensuring that industrial and commercial electrical installations remain safe and operational. With its robust design and manual reset functionality, it offers reliable fault detection and control, helping to prevent equipment damage and enhance overall electrical system stability.

Advantages

This residual current relay stands out due to its highly adjustable sensitivity range, which spans from 0.03A to 30A, allowing for precise calibration based on specific installation requirements. The inclusion of a time delay setting, adjustable from 0 to 4.5 seconds, provides flexibility in preventing nuisance tripping during transient conditions. Its manual reset feature ensures that operators have full control over the system status following a fault, promoting a safer maintenance workflow and preventing automatic restarts that could be hazardous.

Suitable for

• Industrial electrical distribution systems
• Commercial building power management
• Protection of sensitive electrical machinery
• Monitoring leakage currents in complex circuits

This device may not be suitable for residential applications where standard compact residual current circuit breakers are typically required. It is also not intended for use in circuits exceeding its specified voltage rating of 240V or in environments with extreme environmental conditions that fall outside the manufacturer's operational guidelines.

Key specifications

• Voltage rating: 240V
• Sensitivity range: 0.03A to 30A
• Time delay: 0 to 4.5 seconds
• Reset type: Manual

Installation should be performed by a qualified electrician in accordance with local electrical codes. The relay is typically mounted on a standard DIN rail within a control panel. Once mounted, the sensitivity and time delay settings should be configured using the front-facing dials to match the specific protection requirements of the connected load. After a fault has been detected and the relay has tripped, the system must be inspected before the manual reset button is engaged to restore power.

What to consider before purchase

• Verify that the 240V rating matches your electrical network
• Ensure the adjustable sensitivity range covers your specific protection needs
• Confirm that the manual reset functionality aligns with your operational safety protocols
• Check available space in your control cabinet for DIN rail mounting

Usage recommendations: Regularly test the relay functionality to ensure the protection mechanism remains responsive. Always document the configured settings and perform periodic inspections of the electrical circuit to identify potential insulation degradation before a fault occurs.
