LYD-40 Surge Protective Device

Features

· Protecting low-voltage consumers’installations against indirect lightning discharges

· High performance varistor with thermaldisconnection tripping device

· Plug-in module/base design facilitatereplacement of a failed module without the need to remove system wiring etc.

· Protection class: Type 2,Class I

· Pole number:4P

· surge areeare used to guard sensitiveequipments from voltage spike

Application:

LYD-40 series spark gap power surgeprotector is designed and manufactured according to IEC61643-11 and GB18802.1standards. The product has high lightning current discharge capacity, up to50kA (10 350μS), which can prevent direct lightning strikes and other surgecurrent. This product can be mounted on a standard 35mm DIN rail mounting, ithas high safety factor and long service life, it can be applied to single-phaseor three-phase power supply in the class I lightning protection of equipmentand power system with high lightning risk.

- Class II / Type 2 lightning protectivedevice.
– Consisting of a base part and 4 MOV plug-in protection modules.
– For using in the lightning protection zones concept at boundary 1-2.
– The core parts are metal oxide vristor components with high dischargecapacity.
– Low residual voltage and quick response
– Reliable control thanks to Thermo Dynamic Control disconnector.
– With remote signaling contact for control device.
– Fault indication via red mark in the inspection window.
– Protection mode: L/N-PE.
