1. Low residual voltage: Under 8/20μs waveform and 3KA impulse current test, residual voltage is below 700V.
2. Full protection mode, providing comprehensive protection for phase-to-neutral, phase-to-ground, and neutral-to-ground.
3. Long design life, up to 20 years, advanced pre-failure warning, wide environmental temperature range, normal/fault display, suitable for various environments, easy maintenance. 4. Wide operating voltage range, up to 562V, especially suitable for unstable grid conditions.
5. Innovative Sovtrip multiple thermal disconnect technology, anticipating future industry standard requirements, safely disconnects faulty or abnormal power supplies.

Power Surge Protector Description:
1. Advanced protector suitable for main power and distribution systems
2. For single-phase power supplies of 200-280V, use ESP 240M1
3. For three-phase power supplies of 346-484V, use ESP 415M1

Power Surge Protector Application:
Used in main distribution systems to prevent damage to connected electronic equipment such as computers, communication devices, or control equipment from transient overvoltages in the main power supply.

Lightning Protection Performance and Features:
1. Extremely low let-through voltage between all conductors (phase-to-neutral, phase-to-ground, and neutral-to-ground).
2. Maximum surge current far exceeds the worst-case 10KA as described in BS6651 and IEEE C62.41.
3. Repeated protection in lightning-prone environments, with an expected lifespan of 20 years.
4. Innovative Sovtrip multiple thermal disconnect technology, anticipating future regulatory standard requirements, can disconnect faulty or abnormal power supplies (without compromising protection performance).
5. Three-way visual indication of protection status.
6. Advanced pre-failure warning, so you are never left unprotected.
7. Remote indication facilities can connect pre-failure warnings to building management systems, manifested as beeps or indicator lights.
8. Switching active volt-free contacts allows the protector to warn of phase loss situations (e.g., power failure, fuse blow, etc.).
9. Unique flashing alarm mode, indicating potential neutral-to-ground power faults (caused by improper grounding, wiring errors, or unbalanced conditions).
