Class B, Class I, Type 1 SPD AC Surge Protector Device Internal Structure and Working Principle

https://lsp.global/type-1-surge-protector/

Type 1 Surge Protection Device (SPD) range is designed to meet all protection needs of low voltage installations against lightning and industrial surges. These products comply with IEC/EN and environmental standards. The ranges are classified by product type and their power supply network.

Equipment connected to Alternating Current (AC) networks may be exposed to various undesirable electrical phenomena, which can disrupt their operation, cause failures, shorten their lifespan, or even destroy them.

This video demonstrates the Internal Structure (Components and Parts) and Working Principle of Type 1 Surge Protector (SPD).

Specification:
- Type 1 / Class I / Class B
- Impulse discharge current (10/350 μs) Iimp = 25kA @ Type 1
- Nominal discharge current (8/20 μs) In = 25kA @ Type 2
- Maximum discharge current (8/20 μs) Imax = 100kA @ Type 2
- Monobloc design and DIN rail installation
- Visual and remote status indication
- High discharge capacity due to heavy-duty zinc oxide varistor / GDT combination
- Reliable thermal disconnect device
- Energy coordination with other arresters of LSP product family

00:08 Adopting two stacked MOV
00:13 Adopting high-energy GDT
00:18 Adopting wider dual-claw contacts
00:25 Install the terminal of the floating switch on the base
00:29 Place the MOV and metal parts into the base
00:33 Fix the circuit board in the upper cover
00:37 Connect the terminal wires with the circuit board
00:45 High-energy GDT connected directly with metal screw
00:52 Connect the 4 poles with bus bar
00:58 When tension increases, SPD discharges the surge current
01:08 When surge capacity exceeds, the disconnector device released, visible window indicates "Red"
01:16 triggers the microswitch, floating switch transmits the signal to the lamp
