BY10 Series Surge Protective Devices

BY10 Series Surge Protective Devices
Product Detailed
Usage and application scope of BY10 type surge protective device (short name "SPD") is suitable for AC 50/60 Hz,380V

Usage and application scopeUsage and application scope of BY10 type surge protective device (short name "SPD") is suitable for AC 50/60 Hz,380V and the following electric power systems,such as TT, IT, TN-S, TN-C, TN-C-S. It protects the electric network shocked by the thunder or over voltage .Working condition:  1.Height: not more than 2000m   2. Operating temperature : normal -5~+40C Enlarge range: -40~+80C  3. Relative humidity: on condition that room temperature 30%~90%  4. Installed at no notability shocked and virated place  5. Don't be contained in explosion medium,the medium such as air and dust (including conduction dust ) shouldn't come to the degree that can corrode metal or damage insulation.

Model and meaning
Tripping deviceThere’s tripping device designed on the modular of the protector. When the protector is over heat or shocked, the tripping device can automatically separate it from the electric net, at the same time showing the indication signal. It’s green when the protector is normal, red when tripping.Remote signaling contact The products can be produced available with the accessory of remote signaling contact. If one or more of modular of the protector is in malfuction, the contact will be closed, and sending the malfunction signal.Principal parameters Maximum continuous operating voltage : Uc  75   150  275  320  385  440  660V~Test grade:IIVoltage protect level: Up< 350  550  1000   1250    1500   1750   2500VMaximum discharge current : (8/20μS)   Imax    40kA Nominal discharge currrent: (8/20μS)    In   10    15    20kARemote communication terminal parameter

Main Structure and Operating PrincipleIn three-phase four- line system , three phase lines and one zero line are connected protective device to the earth cable . (figure 1 ) . In normal situation , the protective device is high resistance , when the over voltage brings for electric network shocked by thunder or other reasons , the protective device will rapidly transmit in ns , then lead the voltage into earth and protect the electric equipment . As the surge voltage through the protective device and after disappear it will recover to high resistance and not influence the normal operating.

Installation 1. It is installed by standard 35 mm rail.2. The earth cable should choose the double color wire 4mm2 whose length is not longer than 500 mm.3. To avoid the influence to the electric net after the protector is in malfuction, the protector connected to L line should be in series connect with a fuse. The appearance and installation dimension refer to the Fig. 3.
Adjustment, operation, maintenance1. There’s no need to adjust the protector after installation.2. The protector can automatically protect the electric net should it’s installed rightly.3. When operating, check whether the modular scutcheon is red, at the same time check whether the indication red light is lighting, then can change the malfunction device
