Key Features
- 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
- According to IEC61643-11
- Thermal disconnect device
- Screw terminal connection
Applications
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.
Installation Guidelines
- 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.
