Distribution System Over-voltage Protector
　　Patent No.：ZL 02 2 79134.5
　　DSOP-IIIB is voltage-limited surge protector. Its main technology is nonlinear element of original packaging technology (Patent No. ZL 02 2 79135.3). It guarantees the disconnection from the power circuit if the main elements lose function. It has high current-passing capacity, quick in response, and low residual voltage. It is suitable for the protection of phase-II, phase-III, and phase-IV low-voltage power system.
　　■Lightning protector for phase-II, phase-III, and phase-IV power supply inside buildings
　　■High current-passing capacity, with Imax = 100kA
　　■Low residual voltage, lower than the voltage withstanding level of the protected equipment
　　■Short response time, t≤5ns
　　■High performance in heat stability
　　■Indicator of deterioration / malfunction
　　■Automatically disconnects from system if over-heating occurs
　　■Equipped with remote communication I/O
　　■Redundancy backup protection (heat backup)
　　■Modular designed, module replacement while working
　　■Standard 35mm guide, standard size, and easy for installation
　　■Protection level of outer cover is IP2LX
