NPS01-F40-DC110 2P Surge Protective Device

Product Overview

Engineered inside our 10,000-square-meter facility to resolve DC switching spikes, the NPS01-F40-DC110 2P Surge Protective Device provides uncompromising transient protection across critical secondary electrical networks. By uniting premium non-linear varistor discs with an arc-suppression chamber, this NPS01-F40-DC110 2P Surge Protective Device prevents continuous DC arcing when catastrophic grid surges occur. Our engineering team engineered this protective unit for substations, rolling stock auxiliary lines, and power-generation excitation cubicles where uninterrupted operational availability is non-negotiable.

Application Scenarios

Power Utility Substations: 110V DC secondary control racks, protection relay racks, and SCADA telemetry systems.
Electric Rail & Transit: Rolling stock auxiliary power networks and trackside signal power distribution cubicles.
Mining & Heavy Processing: DC trip circuits, magnetic hoist controls, and heavy-duty motor brake circuits.
