Power surge protection device household circuit surge arrester safety protection
Product Details
Surge protector 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
communication line because of the external interference, the surge
protector can guide the shunt in a very short time, thus avoiding
the damage to the other equipment in the circuit. It is usually
installed in the floor distribution box, computer center,
telecommunication machine room, elevator control room and so on.
Product features
1. temperature control protection circuit, built-in thermal
protection;
2. safety insulation of fire retardant and high flame
retardant material
3. The design and installation of the module are
convenient and can be replaced directly.

2. Max continuous operating voltage(UC):385V
3. Voltage protective level(UP):1.8KV
4. Max discharge current(IMAX):40KA
5. Nominal discharge current(IN):20KA
6. Response time(NS):<25
Working principle of product
The function of surge protector is to limit the
transient overvoltage to the power line, the signal transmission
line in the voltage range that the equipment or system can bear, or
to inflow the powerful lightning discharge into the ground, and
protect the protected equipment or system from damage by the
impact.
Use of attention
1. the extra voltage drop caused by the device
terminal.
2. and SPD is established.
3. limit the inductive coupling between the protected
part after installation and the part of the unprotected device, so
we need to make some measurements. The mutual inductance can be
reduced by the separation of the inductive source and the
sacrificial circuit, the selection of the loop angle and the
limitation of the closed loop area.
