With the development of electrification, intelligence, and the Internet of Things, an increasing number of electrical devices are becoming smaller in size, particularly those used outdoors. This trend has resulted in a demand for power surge protectors that are high-performing yet compact. The C-series power surge protector has been designed to meet this demand, with a miniaturized form factor and high discharge capacity, providing reliable protection for power systems.
Power SPD protect all electrical devices (e.g. transformer, junction box, inverter, charging pile, wind power generator, UPS, shield tunneling machine, and shore crane) in power supply or distribution system from surge, which is suit for 24VDC, and IT/ TT/ TN-C/ TN-S AC power supply or distribution system.
The remote signaling alarm function refers to the output of a switch signal to the control system indicating the failure of SPD when the SPD malfunctions.
The remote signaling device of Chengzhu power SPD adopts a mechanical linkage structure with only one micro switch. When any module fails, it can output an alarm signal, which is stable and reliable.
T1: Type 1 test, which is a surge protection device (SPD) tested with the nominal discharge current In, the 1.2/50μs impulse voltage, and the maximum impulse current Iimp.
T2: Type 2 test, which is a surge protection device (SPD) tested with the nominal discharge current In, the 1.2/50μs impulse voltage, and the maximum discharge current Imax.
The preceding overcurrent protection device (i.e. circuit breaker, fuse, etc.) should meet the following two conditions:
The rated current should be smaller than the overcurrent protection device of the main circuit to prevent the main circuit from acting first.
It should not act under In, Imax, or Iimp surge currents. The size of the device varies depending on the specifications.
