Dimension drawing OBO TBS MDP-2 D-24-T

Basic-circuit-drawing-OBO-TBS-MDP-2-D-24-T

The plus of the MDP family – MCR protection for multi-wire systems (testable):

  • Protection device for multi-wire systems (4-pole)
  • Direct shield earthing
  • Easy-mounting, screwless connection terminals
  • Space-saving width of just 8.1 mm
  • Versions with nominal currents up to 10 A
  • High frequency bandwidth up to 100 MHz
  • UL-listed

Besides the high current capacity, the lightning barriers of type MDP offer a narrow installation width of just 8 mm. A separate screen connection permits shield attachment on both sides of the equipotential bonding, thus optimising the shield effect against capacitive and inductive couplings. Depending on the version, a nominal current of up to 10 A can be applied to the devices, meaning that they are thus ideally suited to use in special applications, such as slip ring transmitters or heating systems in wind power systems. When installed, all the MDPs can be checked using LifeControl.

Series protection device, 2-pole, lightning barrier with test function; 5V, 24V, 48V version.

  • Nominal load current 0.58 A
  • Protection device for multi-wire systems
  • Direct shield earthing and screwless connection terminals
  • Space-saving width of just 8.7 mm
  • Protection circuit testable with Life Control
  • High frequency range of 0–100 MHz
  • UL-listed (4DG1)

Application: Universal use on 35 mm DIN profile rail in any standard distribution housing.
