Modular digital voltage and current monitoring relay – 3-phase, 1–100A, 380V, DIN, phase sequence and imbalance protection

Modular three-phase voltage and current protection relay – an advanced DIN rail device designed to monitor the electrical network condition and automatically disconnect the load when dangerous parameters occur: over-voltage, under-voltage, over-current, phase loss, phase imbalance or incorrect phase sequence.

• Adjustable over-voltage protection – disconnects the load when the voltage exceeds the set limit.
• Adjustable under-voltage protection – protects equipment from operating at too low network voltage.
• Adjustable over-current protection up to 100A – allows the current limit to be set according to the load.
• Phase asymmetry protection – disconnects the load when the phase voltage difference becomes too large.
• Phase sequence protection – helps protect motors and other equipment from incorrect phase sequence.
• Phase loss protection – disconnects the load when one of the phases is missing.
• Automatic recovery – the relay can restore operation after the set delay when parameters return to normal.
• Real-time phase voltage display – L1, L2 and L3 status can be monitored on the display.

• Electrical panels – for three-phase input protection against over-voltage, under-voltage and overloads.
• Industrial equipment – for protection of motors, pumps, compressors, fans and other loads.
• Household three-phase systems – for homes or homesteads with three-phase electrical input.
• Commercial facilities – for shops, workshops, warehouses and technical rooms.
• Generator and UPS systems – for voltage stability monitoring and safe disconnection.
• Solar power systems – for network parameter monitoring and protective disconnection.

Three-phase voltage, current, phase sequence and imbalance protection relay up to 100A

The modular digital voltage and current monitoring relay 3F 1–100A 380V DIN is a professional solution for protecting three-phase electrical systems against over-voltage, under-voltage, over-current, phase loss, phase sequence error and phase imbalance.

With adjustable limits, automatic recovery, real-time voltage display, DIN mounting and a wider current range up to 100A, this relay is suitable for electrical panels, industrial equipment, motors, pumps, generators, UPS, solar power systems and other three-phase systems where reliable and flexible protection is required.
