V20-CFunction of pressure-sensitive lightning arrester
As a voltage limiting product, V20-C is equipped with high-energy zinc oxide varistors inside, which have excellent nonlinear characteristics. This component has the advantages of extremely short response time, low residual voltage, high capacitance current, long lifespan, and no freewheeling.
If the varistor ages due to overload, the built-in circuit breaker will interrupt the connection to the power supply, and the color of the fault display window will change from green to red. Remote signaling device (OBO V20-C/FS) with voltage monitoring device for remote signaling. The lightning arrester can be safely hot plugged without power outage.

V20-CApplication of pressure-sensitive lightning arrester
The design purpose of OBO V20-C is to protect low-voltage load equipment below 1000V according to the VDE-0675 standard. It protects electrical equipment from transient overvoltage damage caused by lightning and switch operation. According to the type of power input, there are multiple models available for selection.

V20-CSpecial configuration of pressure-sensitive lightning arrester
After adopting the specially designed optical control system LCS of OBO, remote monitoring of each OBO V20-C becomes effortless. In addition, V20-C is also designed with sound and light alarm devices (OBO V20-C/AS), remote signaling devices (OBO V20-C/FS), and voltage monitoring devices for remote signaling. The lightning arrester can be safely hot plugged without power outage.
Installation specifications:
Basic requirements
1. V20-C should be installed on the AC input side of the switch power cabinet in the computer room, and it should be connected in parallel to the output side of the main circuit breaker.
2. The length of the connecting wire between the lightning arrester and the power supply system should be less than 50cm. The length of the lightning arrester and the ground wire should also be less than 50cm
3. Selection of wire cross-section (according to VDE0100 standard) Unit: mm2

Distribution power cord	≤35	50	≥70
connect wires	10	16	25
ground wire	≥16	25	≥35

4. Due to the characteristics of V20-C/3+NPE/FS, it is recommended to connect a backup circuit breaker in series before the lightning arrester. The recommended capacity of the circuit breaker is 32A, Class A circuit breaker (such as Siemens 5sx2332-5)
5. The wiring installation of FS has three wiring ports, with terminals 1-2 being normally closed contacts and terminals 1-3 being normally closed contacts. Different terminals are connected according to the different user alarm devices.

Attention: It is not allowed to wire protected lines in parallel with unprotected lines or ground wires.
