Voltage and Current Monitoring Solutions

This range of modular monitoring devices is designed to safeguard electrical equipment by continuously tracking supply voltage and current values. These relays feature TRUE RMS measurement to ensure accuracy and include adjustable trip delays to prevent nuisance switching caused by minor, short-term spikes or dips. Available in compact DIN-rail mounting, these devices provide a critical layer of protection by automatically identifying faults such as overvoltage, undervoltage, or phase failure.

General Applications

• Equipment Protection: Safeguarding sensitive electronics and machinery from damage caused by voltage fluctuations.
• Three-Phase System Monitoring: Ensuring industrial motors have all phases present and in the correct sequence.
• Neutral Presence Detection: Monitoring for the presence of a neutral wire in three-phase installations to maintain stability.
• Current Load Management: Monitoring alternating current values to detect overcurrent or undercurrent faults.
• Fault Memory: Utilising latching functions to record and hold fault states for system diagnostics.
