This is a 1-phase current monitoring relay designed for monitoring single-phase AC and DC currents against set thresholds for undershoot and overshoot. Current monitoring relays can be differentiated by their measuring ranges and supply voltage types.

Features and benefits:

• True RMS measurement
• Suitable for frequencies of 40-500 Hz AC and DC
• All units can be digitally set and feature an LCD display with switchable fault memory
• Simultaneous monitoring of overshoot and undershoot currents over the entire measurement range
• Supply voltage: 24-240 V AC/DC
• Bypass time at start: 0.1-20 s
• OFF delay: 0.1-20 s
• Contacts: 1 changeover contact

Product application information:

• Overcurrent and undercurrent monitoring
• Monitoring of the functionality of electrical loads
• Open-circuit monitoring
• Limit switch for analog signals from 4 mA to 20 mA.
