3 Phase AC SPD

CNKA 3 phase ac spd Introduction

China CNKA offers 3-phase AC SPDs made in China, suitable for AC 50/60Hz systems with a voltage of 380V, including TN-STN-C-STATIT and other power configurations. These SPDs can be installed at LPZ1, LPZ2, or LPZ3 connectors and are designed in accordance with IEC61643-1 and GB18802.1 standards.

The installation utilizes a standard 35mm guide rail and includes a fault release device. In the event of a malfunction due to overheating or overcurrent, this device will disconnect the electrical equipment from the power supply and provide an indication signal: green for normal operation and red for abnormalities. Additionally, the module can be replaced while the SPD is still energized.

CNKA 3 phase ac spd FAQ

Q: Where should a DC fuse be installed?
A: It's advisable to place the fuse close to the positive terminal of the battery. This setup ensures that the entire circuit becomes inoperable if the fuse blows. If the positive terminal is grounded, then the fuse should be positioned near the negative terminal.

Q: What are your packing terms?
A: We typically package our products in generic cartons. However, if you have a registered patent, we can use your branded boxes upon receiving your authorization letter.

Q: How do AC fuses differ from DC fuses?
A: The main difference between AC and DC fuses is their ability to interrupt electrical arcs when blown. DC arcs are generally harder to interrupt than AC arcs, which is why DC fuses are often rated for lower voltages, typically around 32VDC.
