NPS02-F40 AC 2P Surge Protective Device
Product Overview
For commercial switchboards and automated control panels operating on single-phase AC supplies, our factory has crafted the NPS02-F40 AC 2P Surge Protective Device to provide balanced two-pole transient overvoltage protection. Utilizing dual high-energy varistor wafers and sensitive dual-spring thermal disconnect mechanisms, this NPS02-F40 AC 2P Surge Protective Device clamps incoming transient spikes to safe thresholds within 25 nanoseconds. We produce this compact modular device to protect industrial machine control cabinets, railway signaling cabins, and TN-S single-phase main sub-distribution panels against electrical grid disturbances.
Application Scenarios
- Industrial Control Cabinets: CNC machinery power inputs, automated packaging equipment, and PLC supply lines.
- Commercial Distribution Boards: Single-phase sub-distribution boards, retail lighting panels, and server room PDUs.
- Railway Signaling Facilities: Trackside signal equipment rooms, level-crossing controls, and barrier power supplies.
