5. Innovative Sovtrip multiple thermal cutoff technology, anticipating future industry standards, safely disconnects faulty or abnormal power supplies.

FURSE Single-Phase Power Surge Arrester Description:
1. Suitable for 90V-150V power supplies and 200-280V power supplies.
2. Suitable for power supplies with maximum current of 5A or 16A.
3. Protectors with /BX suffix are already housed in boxes, IP66 standard, suitable for dirty or humid environments.

FURSE Single-Phase Power Surge Arrester Applications:
These protectors are used for low-current power supplies, such as CCTV cameras, warning panels, and remote sensing equipment.

FURSE Single-Phase Power Surge Arrester Performance and Advantages:
1. Extremely low let-through voltage between all conductors (phase-to-neutral, phase-to-ground, neutral-to-ground).
2. Repeated protection in lightning-prone environments, with an expected lifespan of 20 years.
3. Compact design, suitable for installation on protection systems.
4. Removable rail-mount (DIN) feet, easily snapped onto rails (for non-boxed products).
5. Color-coded terminals for easy identification during installation—gray indicates hazardous end, green indicates non-hazardous end.
6. Boxed products meet IP66 standard, suitable for dirty or humid environments (protector suffix is /BX).
7. Robust outer casing.
8. Sturdy grounding bolt.
9. Maintenance-free.

FURSE Surge Arrester Installation
Connect inline devices and power supplies together, typically installed either inside the equipment panel (or for CCTV cameras, in a nearby enclosure) or on the fused connection line feeding the device.
To prevent damage from transient overvoltages entering through outgoing feeders (e.g., to CCTV cameras or field lighting) at cable exits in buildings. Unless the protector is already boxed, it is installed in ready-made cabinets, boxes, or separate enclosures.

Suitable Accessories for Surge Arresters
If multiple protectors ESP120 -5A or 16A or ESP 240 -5A or 16A are installed together, or if a protector is used alongside video or signal line protectors, they can be collectively grounded in a CME assembly and housed in a suitable WBX enclosure.
