V20-C / 2 


 V 20-C, V 20-C / ... + NPE 
 Product Description 
 Characteristics of V 20-C using the advantages of 
 Power metal oxide varistor protection to cope with frequent moves, long life 
 Pluggable components can be hot plug protection module for testing or replacement 
 1-4 is connected between the base of the terminal through with the flag, easy to install 
 Thermal circuit breakers and window installation instructions 
 To protect the working conditions at a glance 
 NPE spark gap with the protection module uses a range of (TN-CS TN-S TT It), structure is more secure 
 C 25-B + C / NPE into a reverse-protection protection module is simple, professional installation 

 Functions and applications 

 According to DIN VDE 0675, Part 6 (Draft 11.89) A1, A2 requirements, surge protectors V 20-C belongs to C-level surge protector. It protects against all kinds of electrical equipment against voltage surges. Provides a single module to 4 module from the different models. 

 Type V 20-C / 3 + NPE (C level) for TN-CS, TN-S, TT and IT systems in particular, the surge protector. The protection is based on DIN VDE 0100, Part 534/A1 design of the new requirements, and achieve a simple, secure installation. 

 V 20-C contains a high nonlinearity (α> 30) of zinc oxide varistors. The device has a short response time, low levels of protection, high-pass flow and the advantages of long life, especially when the lightning surge protector after the adoption, follow-up to the current does not appear. 

 If the surge protector is damaged due to an overload, the built-in circuit device will prompt action, interrupt and power connections, while fault indication display color from green to red. 

 Installation 

 V 20-C can be easily installed on any distribution box or switch box of the 35 mm rail. Protection of the multi-module module built in the factory has been grounded by a jumper connection, so the protection is only needed once ground (PE) connection. NPE protection module C 25-B + C / NPE and the base between the clever design, the module can not be reverse-inserted. This ensures that the protection module is installed correctly.
