SPD surge protector 60KA

SPD surge protector 60KA
Product Detailed
SPD 60KA surge arrester/surge protector 275/440v;50Hz up to 800 uA for 1p,2p ,3p, up to 600 uA for 1p+N,3p+N

SPD surge arrester /surge protector/surge protective device 60KA

 The surge arrestor consists of a semi-conductor valve element that opens at certain conditions At normal conditions of the system,the surge arrestor has infinitely high resisance between the protected conductors and earthing circuit.At voltage increase due to atmospheric nature or system failure,the valve element opens and leads the excessive voltage to the grounded circuit. After reversion of the normal voltage the valve element closes.The arrestor can endure high momentary overloading.

The surge arrester selection is made according to the overload risk level or atmosphere activity,named B,C or D(from high to low risk level).

1.Functions

protection of heavy-loaded electrical circuits from overloadused to protect not only particular consumers/circuits, but also the whole panelremarkable with high reliability of current characteristicscontrol:automatic switching off at exit failure and recovery after eliminating th danger

2.Technical date

* Rated operating voltage Uc:the operating voltage of the surge arrester 275/440v;50Hz* Surge voltage Up:the voltage created in surge arrester terminals at rated discharge current running:according to the tables* Rated discharge current In-the rated value of discharge current with a sinusoid 8/20 us,which can be repeatedly led to the ground:according to the tables* Full discharge current lmax-the peak value of the discharge current with a sinusoid 8/20 us,which the surge arrester can bear once:according to the table * Constant operating current:up to 800 uA for 1p,2p ,3p,up to 600 uA for 1p+N,3p+N* Indication for damaged surge arrester* Offered in types:1p;1p+N;3p;3p+N

3.Connecting

Fiexible or rigid conductors with corresponding section

4.Mounting

on DIN-rail mounting position:verticalmounting in the distribution box on the front or right before the breaker according to the attached schemes* Breakers plastic material of UV rays and non-flammable* Ambient temperature:-10 +45 * Installation altitude:uThe surge arrester selection is made according to the overload risk level or atmosphere activity,named B,C or D(from high to low risk level).

The company offers th following models of arresters:Model SPD-Bxxxx and HHG3-for systems with exceptionally high risk level .Mounted mainly in the beginning of the installation or in the main panel. Model SPD-Cxxxx-for systems with high or average risk level.Mounted in the beginning of the installation or before the breaker.Model SPD-Dxxxx-for systems with low risk level.Suitable for secondary protection of consumers in combination with SPD-Bxxxx/SPD-Cxxxx. p to 2000m...
