Description:
MJADOM offers a range of overvoltage protection/protective unit for the LSA-PLUS/LSA Profile series 2 Connection and Disconnection modules, in the form of plug-in magazines fitted with 3-pole Gas Discharge Tubes(GDT), In addition to the primary protection afforded by the GDT, additional thermal fail-safe functionality may be fitted, to protect against overheating from interference currents, E.g. power crossing.
The overvoltage protection devices are inserted fully into the contacts of the Connection or Disconnection module, ensuring that the clamps on the sides of the modules grip the lugs of the back mount frame or the earth clips of the profile rails, Connection to LSA PROFILE Disconnection and Connection modules and rails is via the earth contact clips.
MJADOM offers a full range of Krone LSA-PLUS Disconnection Module & Connection Module & Highband Module & STG Module & Back Mount Frame and Gas Discharge Tube Protective Unit.
Features:
Gas discharge tube adopts IDC (Insulation Displacement Connection) design.
Reliable connections
Flame retardant performance
Gas Discharge Tube Arresters Modular design and installation
Compatible with Krone disconnection module.
The 3-pole gas discharge tube surge protector will normally recover after a rated surge passes.
The optional fail-safe 3-pole gas discharge tubes will open the circuit to a fail-safe state if there is a sustained power surge.
GDT Gas Discharge tube Life: durability 500 cycles.
