安装应用 The NKP-DY-JX series cabinet power distribution box can be configured with lightning protection, overcurrent and short-circuit protection, and power failure audible/visual alarm functions. During normal operation, the corresponding indicator lights green; during power failure, the indicator turns red and an internal buzzer sounds a continuous alarm to prompt immediate operator response. During maintenance, pressing the "mute" button temporarily silences the alarm, but the sound will reactivate if new faults occur. Featuring KOJA's patented faceplate design, this compact unit offers convenient wiring, simple installation, intuitive maintenance, and reliable protection, making it an ideal choice for cabinet power distribution systems in equipment rooms.

Configuration Code Explanation
Code Format: 1-2+3-4
Structure Definition:
Main Circuit:
E.g.: 16F=16A with surge protection; 16FB=16A with surge protection & alarm; 32=32A without options
Current rating + options (F=Surge protection, B=Alarm)
Circuit A:
Input/Output count (e.g., 1R5C=1 input & 5 outputs)
Circuit B (if applicable):
Input/Output count (e.g., 1R10C=1 input & 10 outputs)
Omitted when single-circuit
Protection Poles:
1P=1-pole breaker/SPD; 2P=2-pole breaker/SPD
Custom requirements specified separately
Examples:
16FB-1R5C+1R5C-1P = 16A, surge protection & alarm, dual 1-in/5-out, 1-pole breaker
32-1R10C-2P = 32A, no surge/alarm, single 1-in/10-out, 2-pole breaker
