Thermal Protective SPD is a safety type lightning/overvoltage protection device with built-in thermal trip and overheat protection mechanisms based on ordinary surge protectors.
Features:
1. Safe thermal release
Built in temperature control/thermal fuse mechanism, forcing MOV to disconnect from the main circuit when overheated, without open flames or short circuit hazards.
2. Fast response&low residual voltage
Nanosecond conduction (<25ns), residual voltage, effectively protecting precision equipment.
3. Large flow capacity
8/20 μ s waveform: In 10-40kA, Imax 20-80kA, meeting first/second level lightning protection requirements.
4. Status visualization
With window indicator: green normal, red failure, visually judge health level.
5. Maintain friendliness
The module can be plugged and replaced, and supports remote signaling alarm dry contacts for easy remote monitoring.
6. Standard compliance
Compliant with GB 18802.1, IEC 61643-11, UL 1449, etc.
Applications：
1. Building power distribution: residential/commercial main distribution box, floor box (first/second level lightning protection).
2. Industrial control: PLC, DCS, frequency converter, servo drive power front-end.
3. Communication room: switch, server, UPS input protection.
4. New energy: photovoltaic inverters, combiner boxes, energy storage converters DC/AC side.
5. LED lighting: road, tunnel, outdoor landscape lights (anti surge and overheating).
6. Weak current system: monitoring, access control, fire control host, intelligent instrument power supply circuit.
