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.

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.
