LSF and RT switches are rated for 600 V AC and 60 V 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 16 A, 30 A and 40 A versions and carry UL 60947-4-1 certification.
