Χαρακτηριστικά:
Type: T1+T2 Surge protector
Response time: ≤100ns
Labeled connections.
Composite type: 3P+N.
Installation: standard rail 35mm.
Designed to protect low-voltage electrical installations from electrical surges caused by switching action, lightning strikes and electromagnetic pulses.
According to IEC61643-11.
Thermal disconnect device.
Screw terminal connection.
Εφαρμογή:
Protects electrical installations against direct lightning strokes, and discharge the back-current from lightning spreading from the earth conductor to the network conductors.
The device is designed to be used between Zone O and Zone 1 (according to IEC 62305-4 definition of Lightning Protection area).
Can be used to protect three-phase power system.
Matters Need Attention when install SPD:
Determine the discharge current path.
Mark the wires that produce an additional voltage drop on the device terminal.
Mark the PE conductor of each device to avoid unnecessary induction loops.
An equipotential connection is established between the device and SPD.
During installation, connect the device according to the installation diagram, where L is the phase line, N is the neutral line, and PE is the ground line. Do not misconnect the device.
