The Westhomes WSH3-100 Miniature Copper Isolator Switch is a manual switching device designed to safely disconnect electrical circuits from the power supply. It is used for circuit isolation, maintenance safety, and power control in low-voltage distribution systems.
A copper isolator switch provides excellent electrical conductivity, reliable current carrying performance, and good durability. The use of copper conductive components helps ensure stable operation and long service life in electrical applications.
The WSH3-100 Miniature Copper Isolator Switch is designed with a rated current of up to 100A. It is suitable for low-voltage electrical systems requiring reliable manual isolation and switching control.
WSH3-100 indicates the product series and rated current. The “3” represents a three-pole configuration, while “100” refers to the rated current of 100A, making it suitable for three-phase circuit isolation applications.
The WSH3-100 is suitable for residential, commercial, and industrial electrical applications, including distribution boxes, control panels, machinery power isolation, and low-voltage power distribution systems.
An isolator switch is mainly used for manually disconnecting circuits and providing safe electrical isolation during maintenance. An MCB provides automatic protection against overload and short-circuit faults. They are often used together in electrical distribution systems.
Yes. The three-pole design of the WSH3-100 Miniature Copper Isolator Switch makes it suitable for three-phase systems, allowing three phase conductors to be disconnected simultaneously for safer operation and maintenance.
No. The WSH3-100 is designed for isolation and manual switching functions only. It does not provide overload or short-circuit protection, so suitable protective devices should be installed according to system requirements.
The WSH3-100 should be installed in a compatible electrical enclosure or distribution system according to the product specifications. Proper wiring methods and local electrical regulations should be followed during installation.
The WSH3-100 combines reliable isolation performance, durable copper conductive components, and a compact design. It provides a safe and efficient solution for manual circuit isolation in various low-voltage electrical applications.
