The CM-PAS.41S relay is from the CM three-phase monitors range. This relay operates

 with a rated control supply voltage / three-phase measuring voltage of 300-500 V AC

 and has a 2 c/o output with contacts rated at 250 V / 4 A. The CM-PAS.41S monitors

 the phase parameters phase failure, phase sequence and phase unbalance. An ON

delay is adjustable over a range of instantaneous to 30 s (0, 0.1-30 s). A sealable

 transparent cover for protection against unauthorized changes is available as

 accessory. The device offers screw connection technology with double-chamber cage

 connection terminals.

 A 3-phase Contactor suitable for various applications such as Motor starting, Isolation,

 By-pass and Distribution application up to max 690 V.Operated with control voltage,

 versions from 24….690 AC, 50 and 60 Hz

Models ranging from 1 to 64 window with various combinations

Prompt detection and rectification of any system failure or mal-operation is of vital importance for any power or process plant. PROTON Alarm Annunciators continuously monitor the various process parameters and equipment status in power-stations, process plants and these parameter are displayed at centralized control room or on control panel. PROTON Annunciators stand for instant alarming of any abnormal condition occurs during process and protect the valuable equipments. PROTON Annunciators ensure the higher order of reliability and thus provide a comprehensive service to the industry for monitoring, alarm and control of process plant parameters. These highly advanced and compact systems use the latest single chip micro-computer technology for it's design and offer multipoint annunciation with operating sequences as per prevailing standards and with many optional features as indicated aside.
