The Value of Dual-Rated AC/DC Disconnect Switches
The Value of Dual-Rated AC/DC Disconnect Switches
Disconnect switches are an important component in electrical distribution systems, protecting personnel and equipment from harm. Whether for use across the plant or in isolated areas, they ensure a circuit is de-energized during routine maintenance, allowing technicians to work safely on a machine while the rest of the facility remains operational.
Traditionally, users needed separate AC and DC disconnect switches — one to separate the inverter from the electrical grid and another to isolate equipment from the DC source. Now, however, innovative dual-rated disconnect switches now combine both functions into a single user-friendly device.
Features and Specifications of Altech’s Dual-Rated Disconnects
Eliminating the need for separate AC and DC components in industrial and manufacturing applications, Altech’s dual-rated AC/DC disconnect switches — which include the LSF and RT Series — offer one proven switch technology configured for different mounting needs. These components are rated for 600V AC and 60V DC, minimizing the number of parts and streamlining the supply chain.
Designed for DIN-rail and base mounting applications, the LSF Series supports an extended handle application where a shaft extends beyond the electrical box, and an external handle interlocks with it to prevent the box from being opened while power is on.
The RT Series door-mount version features a knob that attaches to the front of the panel for easy access, with rear-facing terminals for simplified installation. Installation requires only a standard 22.5-millimeter push-button panel hole. This model is ideal for applications requiring a local disconnect without shutting down the entire system.
Technical features of the LSF/RT Series include the following:
- Available in 16A, 30A and 40A versions.
- High-grade plastic bodies resist shock and chemicals and can operate in a wide temperature range.
- Silver contacts and rivets ensure long life and better conductivity.
- The spring-loaded design prevents DC current from arcing and burning the contacts after repeated use.
- UL 60947-4-1 certification.
Thanks to these advancements, which combine AC and DC capabilities in the same form factor, Altech dual-rated disconnect switches excel in applications with limited space, such as robotics and lab equipment, where switches are often mounted close to the device.
