Current and Voltage Controls
• 3-phase monitoring relay for phase
sequence/phase loss
• Measures when all 3 phases are present and
have the correct phase sequence
• Output: 10 A SPDT relay
• Plug-in type module
• S-housing
• LED-indication for power supply and output ON
• Power supply is the 3-phased measuring voltage
