The OBO V50-B+C high-energy lightning arrester contains a special varistor circuit composed of zinc oxide varistors with excellent nonlinear characteristics (a30). This enables the lightning arrester to achieve maximum protection even under high-energy overvoltage surges. Its protection level is that under a 12.5KA/(10/350) impulse, the residual voltage does not exceed 1.3kV. Therefore, this lightning arrester can withstand partial lightning current from direct lightning strikes.
1、 Function&Features
functionThe OBO V50-B+C high-energy lightning arrester contains a special varistor circuit composed of zinc oxide varistors with excellent nonlinear characteristics (a>30). This enables the lightning arrester to achieve maximum protection even under high-energy overvoltage surges. Its protection level is that under a 12.5KA/(10/350) impulse, the residual voltage does not exceed 1.3kV. Therefore, this lightning arrester can withstand partial lightning current from direct lightning strikes. When a line overload occurs, the circuit breaker inside the lightning arrester will automatically disconnect the failed lightning arrester module from the main circuit, and the color of the display window used to monitor the working status on the module will change from green to red.
applicationWhen the building itself is equipped with an external lightning protection system (such as installing lightning rods, down conductors, grounding grids, and external shielding), according to the relevant theories of IEC and VDE, OBO is adopted on the 380V/230V low-voltage distribution circuit inside the building
V50-B+C/3+NPE/FSEstablishing lightning protection equipotential connections on power lines can avoid the hazards of fire, explosion, and personal injury caused by lightning strikes.
special configuration
ASSound and light alarm moduleA functional base with sound and light alarms, supplying a 220V single-phase mains power to the base. Under normal circumstances, the light displays green, etc. When a module is damaged, the alarm light changes from green to a flashing red light, accompanied by a "beep beep" alarm sound, reminding maintenance personnel to replace it.
FSRemote signaling contact moduleEquipped with a remote signaling contact function base, terminals 1-2 (normally open contacts) or 1-3 (normally closed contacts) can be selected for connection according to actual needs. And terminal wiring can use 0.14-2.5mm2 multi strand wire or single core wire.
