Disconnect Enclosures
RSP Supply carries a full line of disconnect enclosures built for the safe housing and protection of disconnect switches, circuit breakers, and other electrical isolation components. Available in wall-mount, floor-mount, or free-standing configurations, these enclosures are constructed from durable materials such as mild steel, stainless steel, and fiberglass to suit any environment - from clean indoor installations to harsh outdoor or industrial settings.
Disconnect enclosures serve a critical role in electrical systems, allowing safe shutdown and isolation of power circuits for maintenance or emergency repairs. They are designed to meet demanding safety standards and are available in NEMA Type 3R, Type 4, and Type 4X ratings. This ensures reliable protection against dust, water, and corrosion, making them suitable for both indoor and outdoor applications, including industrial plants, commercial facilities, and utility sites.
These enclosures not only protect electrical components from external damage but also safeguard personnel by preventing accidental contact with energized parts. Many models feature lockable latches or advanced locking systems, mechanical or electronic, to prevent unauthorized access. The construction and finish are designed to withstand impacts, vibration, and exposure to environmental hazards, ensuring long service life and consistent performance.
Disconnect enclosures can accommodate fused or non-fused switches and circuit breakers, providing flexibility for a range of electrical system designs. Options include single-door and double-door configurations, removable panels, and hinge pin doors for quick access during installation or maintenance.
