Product Overview
When acting as the primary gateway for commercial power, your main disconnect switch must be indestructible. The CHNAILE Ultra-High Capacity 2-Pole Circuit Breaker is explicitly engineered to serve as a high-amperage main incomer. Safely routing an immense 160 Amps across AC 230/240V networks, it delivers MCCB-level industrial performance in a compact, modular DIN-rail profile. Certified under the strict GB 14048.2 and IEC 60947-2 industrial regulations, this heavy-duty switchgear ensures uninterrupted power transmission while providing impenetrable defense against catastrophic electrical faults in mission-critical infrastructure.

1. Extreme Industrial Protection Mechanisms
15kA Arc-Quenching Superiority: Heavy loads generate explosive short circuits. Equipped with enlarged, multi-plate arc chutes and powerful magnetic trip coils, this device instantly stifles and extinguishes massive 15,000A fault spikes, preventing major panel destruction.
6kV Lightning & Surge Defense: Featuring a Uimp rating of 6kV, the internal insulation architecture is fortified to withstand severe transient overvoltages, lightning strikes, and grid fluctuations, ensuring critical communication towers remain online.
160A Thermal Load Management: Upgraded with massive bi-metallic sensors designed exclusively for continuous extreme-current transmission. It prevents nuisance tripping during the formidable startup surges of heavy industrial machinery.
2. Oversized Engineering & Robust Wiring Design
Heavy-Gauge Hex Socket Terminals: Visible on the robust casing are heavy-duty hex-socket clamping screws. Unlike standard Phillips screws, these allow maximum torque to be applied when terminating thick, high-amperage industrial cables, guaranteeing zero-gap contact and eliminating dangerous terminal heating.
Industrial V0 Thermosetting Shell: Molded from premium, high-density fire-resistant polymers capable of dissipating the intense thermal load generated by 160A of continuous current.
Reinforced DIN-Rail Anchorage: Due to the heavier cables attached to this unit, the base incorporates a high-tension, vibration-resistant locking mechanism to ensure the breaker stays rigidly mounted on the 35mm rail.
3. Target Application Scenarios
Because of its extraordinary 160A continuous rating and IEC 60947-2 compliance, this breaker is specifically mandated by EPC contractors for:
Telecommunication Base Stations: Serving as the ultra-reliable main AC input switch for remote cell towers and 5G communication hubs.
Commercial Main Distribution Boards (MDB): Acting as the primary incomer for large retail stores, hotel sub-mains, and entire office floor distribution panels.
Grid-Scale Solar & Wind Output: Protecting the massive AC output lines of heavy-duty commercial solar inverters before connecting to the grid.
Heavy Industrial Welding & Fabrication: Safely isolating high-draw single/two-phase heavy manufacturing equipment from the main grid.
