BWQ4-63 Changeover Isolation Switch
The BWQ4-63 Changeover Isolation Switch is a specialized safety device designed for 400V three-phase AC distribution circuits. It provides a clearly visible isolation break point, ensuring absolute safety before maintenance or repair work on distribution cabinets, motors, and photovoltaic equipment. Featuring a standard DIN rail modular structure, this switch allows for load breaking operations and is widely used as a front-end isolation component in complete distribution boxes and industrial control equipment. Note: This device is for isolation purposes only and does not provide overload or short-circuit protection.
Key Features
- Visible Isolation Break Point: Designed with a clear visual indicator of the open/closed status, ensuring that maintenance personnel can verify circuit disconnection instantly for maximum operational safety.
- Standard Modular DIN Rail Structure: Adopts a compact, standardized design compatible with common DIN rails, making installation quick, convenient, and space-efficient within electrical panels.
- Flame-Retardant High-Strength Housing: Constructed with durable, high-grade materials that are resistant to combustion and mechanical stress, perfectly suited for demanding three-phase industrial operating conditions.
