Siemens Voltage Monitoring Relay, 1 Phase, SPDT, 10 → 600V ac/dc, DIN Rail

This monitoring relay is a critical device for monitoring voltage in various electrical applications. It effectively detects both overvoltage and undervoltage conditions, providing essential protection and enhancing electrical safety in industrial environments.

• Monitors voltage levels from 10 to 600V AC/DC for diverse applications
• Adjustable time delay from 0.1 to 20s for customised response
• Includes 1 change-over contact for efficient switching operations
• Incorporates hysteresis functionality for accurate voltage control
• Designed for DIN rail mounting, facilitating installation in control panels
• Allows for external reset to improve operational flexibility

• Employed for voltage monitoring in automated machinery
• Utilised in power supply systems for safeguarding critical loads
• Used in renewable energy installations for protection
• Applied in HVAC systems to protect electrical components
• Functions effectively in switching cabinets to manage voltage safety

The device promptly detects overvoltage and activates the change-over contact to protect connected equipment.

This device is intended for indoor use and should be sheltered from weather elements to maintain its functionality.

Time delay settings can be customised using the integrated controls on the device, tailored to specific requirements.

The maximum installation altitude is 2000m above sea level for effective operation.

This relay is specifically designed for 1-phase voltage monitoring and does not support 3-phase detection.
