20KA to 40KA three-phase power surge protection device Ingress protection rating IP20

Product description

Surge protector, also called lightning arrester, is an electronic device that provides security protection for all kinds of electronic devices, instruments and communication lines. When the peak current or voltage is suddenly produced in the electrical circuit or the communication line because of the external interference, the surge protector can guide the shunt in very short time, thus avoiding the damage of the surge to other equipment in the circuit.

Product specification

Working principle of product

The power surge protector is divided into two parts: explosion proof box type and modular type. A varistor with excellent nonlinear characteristics is adopted. Under normal conditions, the surge protector is in extremely high resistance state, and the leakage current is almost zero, thus ensuring the normal power supply of the power supply system. When the power system surge overvoltage, the power surge protector immediately passes in the nanosecond time, limits the amplitude of the overvoltage to the safe working range of the equipment, and releases the surge energy into the ground. Subsequently, surge protector rapidly changes to high resistance state, so that normal power supply is not affected.

Product features

1. of the slideway buckle design is very difficult to fall off

2. can withstand high lightning shock

3. troubleshooting automatic reset

4. tunnel type terminal connection, tighter wiring is more compact.

Use of attention

1. this product needs no special maintenance. The lightning arrester should be checked regularly, especially in the thunderstorm season and the whole thunderstorm period. When the system fails to doubt the lightning arrester, the lightning arrester can be dismantled and rechecked. If the system is restored to normal after the restoration to the state before use, it indicates that the lightning arrester has been damaged and must be replaced immediately.

2. lightning arresters are connected in series.

3. it should match the working voltage of the protected equipment. Please install according to the installation sketch.
