Disconnector with possibility to add a trigger iSW-NA-63-3N 63A 3-pole A9S70763

Expandable isolating switch

This isolating switch, with a rated current of 63A and a 3-pole (4P) design, is part of the Acti 9 series from Schneider Electric. Designed for safely disconnecting electrical circuits, including in situations requiring remote tripping, it is a reliable solution for both professional installers and end users. The ability to add overcurrent and undervoltage releases increases the functionality of the device, adapting it to the specific needs of the installation.

Functionality and application

This switch is used in electrical installations where circuit isolation and safe disconnection are required. Thanks to the possibility of equipping it with additional modules – a door drive, auxiliary contact or plug-in base – it can be easily integrated with various control and monitoring systems. The Visi-Safe indicator provides visual confirmation of contact opening, which is crucial for safety during maintenance and service work. The design allows for mounting on a DIN rail, which simplifies and speeds up installation.

Key features and benefits

• Versatility: The ability to expand with additional functions (releases, door drive, auxiliary contact) allows the switch to be adapted to specific application requirements.
• Safety: The Visi-Safe indicator guarantees visual verification of the circuit disconnection status, minimizing the risk of accidental reconnection.
• Easy installation: Snap-on design and the ability to mount on a DIN rail greatly simplify the installation process.
• Strength: Rated short-circuit current withstand of 800A/1s provides resistance to overloads and short circuits.
• Compliance with standards: Meets the requirements of EN 60947-3 and IEC 60947-3 standards, guaranteeing safety and reliability.
• Width: Occupies only 4 modules on the DIN rail, saving space in the distribution board.
• Rated voltage: Designed to operate in networks with a voltage of up to 415V AC.
• Forced separation: Provides complete circuit isolation in accordance with DIN VDE 0113 standard.

Technical parameters in practice

Rated current of 63A means that the switch is adapted to protect circuits with such a current intensity. Rated switching capacity at 5kA informs about the maximum short-circuit current that the device can safely interrupt. A width of 4 modules allows for efficient use of space in switchgear cabinets. Protection degree IP20 indicates protection against finger contact and against the ingress of solid objects larger than 12.5 mm – important for safe use in standard environmental conditions.
