Nov. 4, 2025 – Altech Corporation, a leader in industrial automation solutions, announces the launch of its dual-rated AC/DC disconnect switches for industrial and manufacturing applications. This product line, which includes the LSF and RT Series, offers one proven switch technology configured for different mounting needs.
LSF and RT switches are rated for 600V AC and 60V DC, eliminating the need for separate AC and DC components. 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.
Other technical features of the LSF/RT Series include:
- Switch bodies are made from high-grade plastics that 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.
- Both LSF and RT mounting options consist of only a few parts—unlike most other multi-part products on the market that can be complex to install.
- They are available in 16A, 30A and 40A versions and carry UL 60947-4-1 certification.
