Functions and applications: according to DIN VDE 0675, Part 6 (Draft 11.89) A1, A2 requirements, surge protector V 20 - C belongs to grade C of the surge protector. It can protect electric equipment from various voltage surge harm. Can provide from single module to 4 module of different types. Type V 20 - C / 3 + NPE (C level) is used for TN - C - S, TN - S, TT and IT system in other surge protector. This protector is according to DIN VDE 0100, Part 534 / A1 new demand for design, and achieve simple, safe installation. V 20 - C contains a high nonlinear characteristics (α > 30) of zno varistor. This device has the response time is short, the protection level is low, the high flow rate and long life advantage, especially when lightning surge through the protector, subsequent current won appear. If the surge protector due to overload happen damage, the built-in trip will be duly action, interrupt and the connection of power supply, and at the same time fault indicator display window colors from green to red. Installation: V 20 - C can easily installed on any distribution box or switch box 35 mm guide rail. Many module protector of each module in the factory has the built-in ground jumper wire connection, so protector just need to do a ground connection (PE). NPE protection module C 25 - B + C/NPE and between the base of the clever design, make the module cannot be reverse insert. This ensures that the protector module properly installed.
Characteristic V 20 - C use advantages
Electricity metal oxide varistor protector can cope with frequent action, long service life
Can plug type parts protector module can be charged plug testing or replacement
1 to 4 piece base has connection between on through the belt mark terminal, easy to install
Thermal circuit breaker and Windows indicating device to protector working condition be clear at a glance
Take NPE spark gap module protector use range (TN - C - S TN - S TT It), the structure is more secure
C 20 - B + C/NPE has reverse insert protection protector module is simple, professional installation
