Multifunctional Magnetic Hydraulic Circuit breakerBreaker for Equipment L-MN5-50 Series

 

Range of use:

  L-MN5-50 is a new generation of minitype breakers to international standard and with superior structure. Functioned as protection to overload and short circuit for electrical system below 50HZ230V, 415V* or 400HZ, 280V*, or for the unfrequent connecting and breaking, they are widely used in the control system of computers, peripheral equipments, precision arc welders, communication equipments, power system, UPS equipments, railroad locomotives, ships, elevators and so on, as well as in petrol generator sets.
  This type of breakers (CBE) for equipment conform to GB177011999 and EN 609342001, and have been certified to TUV, CCC and CE.
  They can be equipped with auxiliary contacts, shunt releases and etc. for signal indication and distant operation, making your design or equipment functions greatly upgraded, and range of use more extensive, while the total cost can be lowered.

Model and meaning:
working conditions:

1. Ambient air temperature -40°C~+85°C
2. Relative humidity of air not greater than 95% (+40°C)
3. Gradient to vertical surface not exceeding 5 degrees.
4. Occasion with impact and vibration.
5. No gas and dust (including conductive dust) in non-explosive medium that can corrode the metal or damage the insulation.
6. Area not to be invaded by rain or snow.
