305PN is a black switch guard designed for 2 or 3-position switches in the APEM 12000, 3500, 600H, and 6000 series. This Series 300PN guard features a lever protection mechanism that keeps the lever protected in the position where left by the user without locking it. The guard is designed for Ø 11.9 or Ø 12 mm bushings and includes Ø 1.5 mm holes for optional seal wiring. Constructed with a black stainless steel support plate and thermoset or thermoplastic cap, it operates reliably across a temperature range of -40°C to +85°C and passes a 96-hour salt spray test per IEC 68-2-11. This switch guard is ideal for applications requiring accidental lever operation prevention while maintaining easy access to switch positions.
