Schneider Electric NS1000 N (ComPacT NS1000N) Moulded Case Circuit Breaker Product Description

Overview

Schneider Electric NS1000 N is a heavy‑duty moulded case circuit breaker from the Schneider Electric ComPacT NS series for low‑voltage AC power distribution protection. This Schneider Electric moulded case circuit breaker features 1000 A rated current and N breaking capacity grade (50 kA at 415 V AC). It is available in fixed or withdrawable versions, supporting 3‑pole or 4‑pole configurations and compatible MicroLogic electronic trip units. NS1000 N is widely used for main and branch protection in industrial, commercial and infrastructure switchgear cabinets, suitable for new panel assembly, equipment renovation and spare‑part replacement.

Features

Schneider Electric NS1000 N moulded case circuit breaker adopts high‑performance arc quenching chamber to achieve reliable short‑circuit interruption. This Schneider Electric moulded case circuit breaker can be fitted with MicroLogic 2.0 / 5.0 / 6.0 trip units to configure adjustable overload, short‑time delay, instantaneous and earth‑fault protection curves. NS1000 N supports built‑in metering functions for current, power and energy when paired with advanced trip units. The Schneider Electric moulded case circuit breaker reserves mounting positions for motor operator, shunt release, undervoltage release and auxiliary/alarm contacts for remote tripping and status feedback. This Schneider Electric moulded case circuit breaker complies with IEC 60947‑2 standards and supports Modbus communication modules for SCADA and energy management connection.

Principle

Schneider Electric NS1000 N moulded case circuit breaker uses the MicroLogic electronic trip unit to continuously monitor the main circuit current. When overload occurs, the trip unit triggers delayed tripping according to the selected long‑time curve. When short‑circuit current appears, the instantaneous protection function acts quickly to separate main contacts. The arc chute cools and splits the arc to complete safe fault isolation. Communication accessories transmit real‑time electrical values, alarms and breaker status to upper control systems.

Applications

Schneider Electric NS1000 N moulded case circuit breaker is widely deployed in factory power distribution rooms, commercial buildings, data centres, water treatment plants and general OEM power control cabinets. This Schneider Electric moulded case circuit breaker serves as incoming feeder protection, large motor feed protection and bus branch protection. NS1000 N fits switchgear retrofit and spare replacement of legacy ComPacT NS high‑current MCCB systems. It protects cables, transformers and loads against overload and short‑circuit damage.

Installation & Maintenance Notes

Follow official Schneider Electric ComPacT NS operation manuals during installation of Schneider Electric NS1000 N moulded case circuit breaker. Apply correct tightening torque for main terminals to avoid overheating. Select matching MicroLogic trip unit and accessories before commissioning and back up protection settings before replacement. Conduct regular inspection of contact condition, handle operation and cable tightness, especially in dusty and high‑vibration environments. Confirm exact model NS1000 N, pole count and breaking capacity grade during spare‑part swap‑out to guarantee compatibility with existing cabinet and protection scheme. Maintain cabinet ventilation to prevent excessive ambient temperature from affecting trip accuracy.
