Schneider Electric NW20H1 2000A 3 Pole Air Circuit Breaker For Low Voltage Power Distribution Systems

Schneider Electric NW20H1 2000A 3-Pole Air Circuit Breaker is a rugged protective device engineered for reliable protection and switching in low-voltage power distribution systems across industrial and commercial facilities.

Built to safeguard main incoming feeders and switchboards, the NW20H1 delivers high interruption capacity with adjustable trip settings that let you tailor protection to your exact network coordination. This means faster fault clearance where it matters most, while minimizing unnecessary trips elsewhere in the system.

• Current rating and configuration: 2000 A, 3-pole air circuit breaker for robust three-phase protection.
• Protection for critical power distribution: Ideal for main incoming feeders and switchboards where reliable interruption control is essential.
• Adjustable trip settings: Fine-tune protection curves to match upstream devices and load characteristics, improving selectivity and uptime.
• High interruption capacity: Built to interrupt faults quickly in demanding low-voltage networks, reducing arc energy and equipment stress.
• Durable, heavy-duty design: Engineered for frequent switching and long service life in challenging environments.
• Easy integration: Works with common low-voltage distribution architectures and Schneider Electric systems for streamlined installation and maintenance.

Use cases and scenarios

• Protect the main incoming feed in industrial plants, manufacturing lines, and large commercial facilities, ensuring rapid fault clearance and equipment protection.
• Upgrade or retrofit existing switchgear where a 3-pole, 2000 A air circuit breaker is required for coordinated protection with upstream devices.
• Provide dependable power distribution with external coordination settings that support planned maintenance windows and reduced downtime.

Why choose the NW20H1 over simpler protective devices? It combines the simplicity of an air circuit breaker with the precise, adjustable protection needed for complex, load-heavy networks. Its 3-pole configuration delivers balanced protection across phases, while the robust construction minimizes trip nuisance and extends service life in demanding facilities.
