NAE Disconnects
NAE disconnect switches are designed to provide reliable electrical isolation in industrial and commercial power systems. Commonly used during maintenance and servicing, these disconnects allow operators to safely remove power from downstream equipment, ensuring circuits can be accessed without an electrical hazard. Their clear on/off indication provides a visible and dependable confirmation that power has been disconnected.
When placed in the off, or open, position, NAE disconnects create a non-contact electrical break through a highly insulated air gap. This design prevents current flow and delivers a clear visual and physical signal that the circuit is safely isolated. The user-friendly handle mechanism allows straightforward manual operation, supporting safe lockout and maintenance procedures in demanding environments.
NAE disconnects are available in both fusible and non-fusible configurations. Fusible disconnects combine circuit isolation with overcurrent protection by incorporating fuses, while non-fusible disconnects are strictly used for switching and isolation. Selecting the appropriate type ensures compatibility with system requirements and supports safe, compliant electrical installations.
FAQs
Q: What is an NAE disconnect used for?
NAE disconnects are used to manually remove and restore power to electrical equipment, allowing safe access for maintenance and servicing.
Q: What is the difference between fusible and non-fusible disconnects?
Fusible disconnects include fuses that provide overcurrent protection, while non-fusible disconnects are used only for electrical isolation and switching.
Q: Do disconnect switches provide circuit protection?
Non-fusible disconnects do not provide circuit protection. Fusible disconnects protect installed fuses, but circuit breakers or additional protection devices may still be required.
Q: Why is a visible air gap important in a disconnect?
A visible air gap confirms that the circuit is physically open and that no current can flow, providing a clear safety indication for operators.
Q: Are disconnects used with high-voltage circuits?
Yes, disconnects are commonly used in circuits with higher voltages to allow safe power isolation before accessing electrical enclosures.
Why Buy NAE Disconnects: Fusible & Non-Fusible from RSP Supply
RSP Supply offers a full selection of NAE fusible and non-fusible disconnect switches designed for safe and reliable electrical isolation. Our disconnect solutions support industrial and commercial applications requiring clear power control and dependable operation. Customers rely on RSP Supply for trusted electrical components, technical expertise, and products built to meet safety and performance standards in demanding environments.ccurs, they will need to be replaced as they are only intended to be used once. Circuit breakers can be reset, but are not intended to switch power on and off as their main function. In many cases it is necessary to have both an electrical disconnect and a circuit protection device to ensure that any hardware on the circuit does not become damaged because of overcurrent or power surges.
