Meba lightning arrestor MBD1-RC40 (hereinafter called SPD) in order to meet with user demand, we developed new generation MBD1-R series protector with built- in circuit breaking device, to limit surge current, overvoltage, over-current occurred in the power system due to some reasons, working in the system of AC 50Hz, rated voltage 380V and below to prevent surge voltage from damaging electric equipment.
MBD1-R series protector has integrated short circuit protective function in its SPD module, fuse not needed again, it can be mounted on 35mm railway, compared with normal combination of fuse + SPD module, there has following advantages:
– Residual voltage reduce more than 50%, for normal combination, fuse body and connected conductor have inductance, and will result in residual voltage, but MBD1-R series almost has no residual voltage at this case, therefore it can get better result of protecting equipment.
– Easy installation, saving space, saving installation cost in cabinet.
– Quicker response speed, comprehensive performance being improved.
– Better N point: no matter which step of circuit, there has shortest distance for discharging surge current, residual voltage decrease more.
Fast response time: less than 25ns
Low limited voltage
Large current carrying capacity
Normal state: white color, invalid state: red color
Kelvin wiring mode available.
