Eaton® MSDI
Class I & II/Cat D & C, Three Phase Surge Diverter
The MSDI surge diverter is designed to provide point-of-entry
protection against power surges caused by external sources
such as lightning strikes & substation switching. Common-mode
protection is available for sites remote from the M.E.N. point
including industrial sites & rooftops in multi-storey
buildings. An ideal device for all Category locations.
The MSDI surge diverters utilise MOV protection for both
differential & common-mode protection. Multiple MOV devices
are used in parallel for primary circuit redundancy. The status of
protective devices is continuously monitored & displayed using
LED bar-graph indicators. All MOV devices are thermally fused
& isolated by ceramic fuses.
Shunt Surge Diverter, 3 Phase 200kA
Typical applications:
• All Power Circuits including "Point-of-Entry"
• Telecommunications Systems & Rectifiers
• Process & Control Systems & UPS Systems
• Computer & Medical Systems
• Multi-storey buildings
• All sensitive Electronic Equipment
MSDI unit is provided with an alarm relay. The alarm function
provides a summary alarm output for protection degradation as
well as power failure. The alarm may be configured to indicate
either partial or total protection failure. The level of protection
remaining is indicated by LED bar-graph indicators on the front
panel. A summary alarm relay contacts provide remote
signalling to remote equipment.
Key Features:
• 3 Mode, 2 Stage Surge Diverter
• Surge suppression rating of 200kA
• Enclosed in IP24 cabinet
• LED Bargraph display on each phase
• Protection Fail Alarm Relay
• 5 Year Warranty
