AM3-20/3+NPE
AM3-20 3+NPE modular power surge protector is designed according to IEC and GB standards. The surge protector has strong surge discharge capability, and the maximum discharge current per bit is 20kA (8 20μs), which is suitable for low-voltage power distribution. For all levels of protection of the system, various combinations can be selected according to different power distribution systems (TT TN IT). - High energy surge protection
- Built-in instantaneous overcurrent disconnect device
- Remote signaling alarm interface (optional)
- Pluggable Replacement Modules
- Failure detection indication
- The maximum discharge current of a single module is 20kA (8/20μs)
- Standard Modular Installation
- Built-in thermal circuit breaker
- Response speed: 10-9 seconds
- Plug-in foolproof design
