Current Monitoring Relays

RSP Supply carries a full line of current monitoring relays designed to detect and protect against overcurrent and undercurrent conditions in industrial and commercial electrical systems. Available in single and double pole configurations, these relays safeguard equipment by signaling alarms or disconnecting power when abnormal current levels are detected, helping prevent costly downtime and equipment failure. Current monitoring relays play a critical role in maintaining operational safety and efficiency. When current flow deviates from normal levels, these devices automatically trigger control signals, allowing operators to take corrective action or automatically shut down affected systems. They are used in a wide variety of applications, including motor protection, process monitoring, and power distribution systems.

Schneider Electric Harmony control relays provide comprehensive monitoring and detection of system parameters such as current, phase, voltage, frequency, and temperature. With advanced digital configuration using the Zelio NFC App, users can precisely set monitoring thresholds and timing delays in minutes, seconds, or milliseconds for optimal control. Phoenix Contact EMD-BL compact monitoring relays are designed for simplicity and reliability in machine and building automation. They monitor electrical and physical parameters including current, voltage, phase sequence, load, and temperature, making them suitable for series production, system integration, and facility installations.
