The Westhomes WSH3-100 Series Industrial Isolator Switch is a manual disconnect device designed for safe electrical isolation in industrial and low-voltage power distribution systems. It allows operators to disconnect circuits during equipment maintenance, inspection, or emergency situations.
The WSH3-100 is suitable for industrial facilities, commercial buildings, distribution panels, machinery control systems, and other low-voltage electrical applications where reliable circuit isolation is required.
The WSH3-100 model indicates a three-pole isolator switch series with a rated current of 100A. The three-pole configuration is designed for applications where three-phase circuit isolation is required.
An industrial isolator switch is used to manually disconnect electrical circuits from the power supply, providing a visible and reliable isolation point. It helps improve safety during maintenance and prevents accidental energization of equipment.
An isolator switch is mainly used for manual isolation and does not automatically protect against electrical faults. A circuit breaker provides automatic protection against overloads and short circuits. In many industrial systems, isolators and circuit breakers work together to provide both safety isolation and circuit protection.
Yes. The WSH3-100 Series Industrial Isolator Switch is designed with a three-pole configuration, making it suitable for three-phase electrical systems where simultaneous disconnection of three phase conductors is required.
No. The WSH3-100 is designed for isolation and switching functions only. It does not provide overload or short-circuit protection, so appropriate protective devices such as MCBs or MCCBs should be installed according to the electrical system requirements.
An industrial isolator switch provides a safe method to disconnect power before maintenance or repair work. It helps protect operators and maintenance personnel by ensuring that equipment can be completely isolated from the power source.
The WSH3-100 should be installed in a suitable electrical enclosure, distribution board, or industrial control panel according to the rated voltage, current, wiring requirements, and applicable installation standards.
The WSH3-100 Series offers reliable manual isolation, robust construction, and stable performance for industrial electrical applications. Its compact design and dependable switching capability make it suitable for safe power isolation in various low-voltage systems.
