3-Phase Monitor with Adjustable Trip & Restart Delays
The 22M 3-Phase Monitor provides essential protection for industrial electrical systems. Its adjustable trip delay, ranging from 1 to 30 seconds, allows for precise fault response tailored to specific equipment requirements. A configurable restart delay, from 1 to 500 seconds, prevents immediate re-energization, safeguarding machinery from rapid cycling. Operating across a 190-480 VAC range at 50/60Hz, this monitor accommodates diverse power infrastructures. It features 2X SPDT 10A output contacts for reliable control integration. The unit's manual reset capability ensures controlled system restoration after an event. It monitors for under voltage (90% ±1% trip), over voltage (110% ±1% trip), and voltage unbalance (2-8% adjustable trip) using RMS measurement. This device offers robust monitoring capabilities for critical applications, ensuring operational continuity and equipment longevity.
