Description

The Sezgin Residual Current Monitoring Relay is an industrial control and warning device designed to continuously monitor residual current levels in electrical installations, enabling early detection of insulation faults, leakage currents, and potential safety risks. It operates together with a toroidal residual current transformer to provide accurate and reliable monitoring.

With its compact design suitable for DIN rail mounting, the Sezgin residual current monitoring relay can be easily integrated into control panels. The sealable housing protects against unauthorized adjustments, while the adjustable tripping delay time helps prevent nuisance tripping caused by transient conditions.

Technical Features and Advantages

• Sealable enclosure to prevent unauthorized access
• DIN rail mountable design
• Adjustable tripping delay time (0 s – 5 s)
• Compatible with toroidal residual current transformers
• Reliable and stable performance for industrial applications

Harmonic Filtering Function

Models equipped with harmonic filtering are designed to prevent nuisance tripping in panels supplying loads that generate high harmonic distortion, such as motor drives, UPS systems, arc furnaces, and welding machines.

Applications

• Industrial facilities
• Energy monitoring and control panels
• Power factor correction panels
• Systems with high harmonic distortion
• Critical load monitoring applications

Product Models

NOTE: Residual current monitoring relays must be used together with a compatible toroidal residual current transformer to ensure accurate measurement and proper system operation.
