MSP
2,3 Motor protection
- these relays are no longer available, but can be
replaced by the MSP-4 Motor protection relay.
More details, on how to do so, can be found here
MSP
4 / C311 Motor protection
- 3 phase RMS based on avarage measurement
- Overload protection After powerdown, the
therminal capacity is memorized for up to 8 hours, as well as the trip
cause. (when there is one)
- Trip relay: Inhibit, Stall, Overload, Phase
loss, Phase reversal, Ground fault.
- Auxiliry relay: Overcurrent/Undercurrent
detection, Star/Delta
- Ground fault detection, uses an external
core-balance CT, or measures the spill current from the existing (build
in) CT's
- Thermistor input
- 4-20 mA output
MSP 1000, Motor protection
- Microcontroller based system. Computer
programable (RS232)
- RMS measurement
- Eeprom memory: memorizes thermal capacity,
statistics and trip causes at all times.
- Numeric LCD display: displays Readings, Settings
and Trip causes
MSP 2000, Motor management and
protection
- All the functions the MSP 1000 offers, and more...
- Motor management.Starting, Starting reverse,
Stopping, etc.
- Controls by: The display (local), External
switches (remote), or supervisory computer (telemetrical)
- Extra contactor inputs to detect failing/frozen
contactors.
- Alpha numeric display: displays Trip-causes,
Readings, Settings
RTD 3, temperature- measusement and
protection
- 3 temperatures are continiously measured
(by means of PT-100 elements)
- Trip relay, active then the highest temperature
exeeds the (Settable) TRIPLEVEL
- Alarm relay, active then the highest
temperature exeeds the (Settable) ALARMLEVEL
