The Schneider NW08HA is part of the MasterPact NW low-voltage switch-disconnector family. Designed for industrial power distribution applications, it provides switching and isolation functions for electrical systems requiring dependable operation.
With an 800 A rated-current designation, the NW08HA is intended for installations where its electrical characteristics meet the requirements of the distribution network. Different equipment configurations may involve variations in pole arrangement, mounting type, and connection accessories.
An important consideration when selecting this model is its switch-disconnector function. Unlike a conventional automatic circuit breaker, it should be incorporated into a properly coordinated electrical protection system rather than relied upon as the sole device for overload and short-circuit protection.
For electrical contractors, maintenance departments, and industrial equipment distributors, the NW08HA is a relevant MasterPact component to consider when maintaining or upgrading low-voltage distribution assemblies.

Applications – Industrial Power Distribution and Electrical Isolation
The Schneider NW08HA belongs to the MasterPact NW family of low-voltage switch-disconnectors. It is designed for industrial and commercial power distribution systems where reliable switching and electrical isolation are essential.
Typical application areas include:
Industrial main distribution switchboards
Commercial building power distribution systems
Manufacturing plant electrical installations
Low-voltage power control assemblies
Electrical systems requiring high-capacity switching and isolation
With an 800 A rated current, the NW08HA is suitable for consideration in distribution systems that require this level of switching capacity. Its application must be evaluated according to system voltage, short-circuit conditions, and external protection requirements.

800 A rated current: Designed for distribution applications requiring an 800 A switching device.
HA performance classification: Provides defined electrical characteristics for short-circuit making and short-time withstand performance.
Electrical isolation: Supports safe isolation procedures when correctly installed and operated.
Flexible configurations: Available in different pole arrangements and mounting configurations, depending on the selected reference.
Industrial integration: Designed for integration into MasterPact NW switchboard assemblies.
Convenient spare-parts identification: Accurate model identification helps simplify equipment maintenance and replacement sourcing.
Technical FAQs – Schneider NW08HA
Q1: What is the Schneider NW08HA used for?
The NW08HA is a MasterPact NW switch-disconnector designed for switching and isolating electrical circuits in low-voltage power distribution systems.
Q2: What is the rated current of the NW08HA?
The NW08HA is associated with an 800 A rated-current configuration under its specified operating conditions.
Q3: Is the NW08HA a conventional automatic circuit breaker?
No. The NW08HA is a switch-disconnector. It provides switching and isolation functions and should not be assumed to offer the same integrated overload and short-circuit protection as an automatic circuit breaker.
Q4: What does the HA designation indicate?
HA identifies a performance category within the MasterPact NW switch-disconnector range. It refers to defined electrical characteristics for demanding switching and distribution applications.
Q5: Can the NW08HA be used in a 690 V AC system?
Certain configurations in this product family are designed for operation at up to 690 V AC. The exact voltage rating should be confirmed against the complete product reference and nameplate.
Q6: Is the NW08HA available in three-pole and four-pole versions?
Different pole configurations may be available. The required three-pole or four-pole version should be confirmed before ordering.
Q7: Does the NW08HA provide overload protection?
The switch-disconnector should not be treated as a standalone overload-protection device. An appropriate external protection arrangement is required according to the electrical system design.
Q8: What should be checked before replacing an existing NW08HA?
Check the complete catalog number, rated voltage, pole configuration, fixed or drawout mounting arrangement, connection accessories, and chassis compatibility.
Q9: What maintenance inspections are recommended?
Follow the manufacturer's maintenance instructions. Relevant inspections include checking electrical connections, contact condition, operating mechanisms, insulation, and signs of overheating or mechanical damage.
Q10: Can the NW08HA replace an NW08H1 circuit breaker?
They should not be considered interchangeable. The NW08HA is a switch-disconnector, while the NW08H1 is a circuit-breaker designation. Their operating functions and protection arrangements are different.
