1. Low residual voltage: Under 8/20μs waveform and 3kA impulse current test, the residual voltage is below 700V.
2. Full protection mode, providing comprehensive protection between phase and neutral, phase and ground, and neutral and ground.
3. Long design lifespan of up to 20 years, advanced pre-failure warning, wide environmental temperature range, normal and fault status display, suitable for various environments, and easy maintenance.
4. Wide operating voltage range, up to 562V, particularly suitable for unstable grid conditions.
5. Innovative Sovtrip multiple thermal disconnect technology anticipates future industry standards, safely disconnecting faulty or abnormal power sources.

Description:
1. Remote display allows both the display and protector to be installed in position.
2. Advanced protector for main power and distribution systems.
3. Suitable for three-phase power supplies ranging from 346-484V.

Applications:
Typically installed in large three-phase switchgear to protect connected electronic systems, such as computers, communication equipment, and control devices.

Performance and Advantages:
1. The remote display allows the protector to be installed near the feeder or on the first circuit of the distribution board, while the display can be positioned for easy visibility, such as on the front of the cabinet.
2. Extremely low let-through voltage across all conductors (phase-to-neutral, phase-to-ground, and neutral-to-ground).
3. Maximum surge current significantly exceeds the worst-case 10kA as described in standards like BS6651 and IEEE C62.41.
4. Repeated protection in lightning-prone environments with an expected lifespan of 20 years.
5. Innovative Sovtrip multiple thermal disconnect technology anticipates future standard requirements, disconnecting faulty or abnormal power sources without compromising protection performance.
6. Slim remote display provides three-way indication of protection status.
7. Standard connection includes a 1-meter cable between the protector and display.
8. Plug-in electrical connectors between the protector and cable facilitate easy connection.
9. Advanced pre-failure warning ensures continuous protection.
10. Remote indication facilities can connect pre-failure warnings to building management systems via audible alarms or indicator lights.
11. Converted active volt-free contacts allow the protector to warn of phase loss conditions (e.g., power outages, blown fuses, etc.).
12. Unique flashing alarm mode indicates potential neutral-to-ground power faults caused by improper grounding, wiring errors, or unbalanced conditions.
13. Robust steel enclosure for the protector and durable ABS housing for the display.
14. Protector base ensures exceptionally low grounding inductance when connected to metal panels.
15. Protector unit features simple mounting holes for horizontal installation.
16. Easy installation of the remote display using standard drilling tools.
17. Remote display includes integrated mounting fixtures and panel drilling templates.
18. Compact design suitable for installation on distribution boards.
19. Maintenance-free.

Installation:
Install the protector unit in the same manner as the ESP 415M 1. Position the remote display, ensuring the cable is long enough for unobstructed routing within the cabinet and leaving at least 60mm at the front of the panel (for interconnection cables). Use the template (installation instructions included with each unit) to mark the mounting holes. Drill the holes, screw into place, and connect the interconnection cable from inside the cabinet to the back of the display.
