Schneider Electric NS800N 800 Amp 4 Pole Air Circuit Breaker For Industrial Low Voltage Power Distribution

For facilities where power reliability and rapid fault isolation are non-negotiable, the Schneider Electric NS800N 800A 4-Pole Air Circuit Breaker is engineered to deliver robust protection across your low-voltage distribution network. This heavy-duty device is purpose-built for industrial and commercial environments, where dependable switching of power feeders means less downtime and longer equipment life.

Key capabilities that differentiate the NS800N

• 800 A rating, 4-Pole configuration: Protects a three-phase system with neutral as needed, providing explicit isolation across all phases for clearer fault clearance and simpler control strategies.
• Adjustable trip settings: Tailor protection curves to your installation’s fault-current levels and protection philosophy, enabling precise coordination with downstream devices and reducing nuisance trips.
• Air circuit breaker technology: Delivers reliable interruption with robust arc quenching, designed for demanding loads and environments with limited downtime for servicing.

What this means in practice

In industrial power distribution, NS800N is ideally positioned for main incoming feeders, switchboards, and any critical power distribution segment where reliability and predictable clearance times matter. By combining high interrupting capacity with adjustable protection, it helps safeguard motors, drives, transformers, and other essential equipment from short-circuit and overcurrent events.

Ideal use cases

• Protecting main feeders feeding large switchgear in manufacturing plants
• Isolating and protecting critical feeders in data centers or critical facilities
• Providing reliable upstream protection in commercial buildings with heavy electrical loads
• Coordinating with downstream protective devices to achieve selective trips
