The WL series is a range of medium voltage vacuum circuit breakers designed for indoor use. These breakers incorporate a unique separate pole technique where each pole contains a vacuum interrupter encapsulated directly in resin during the moulding process. This method ensures enhanced protection against impact, dust, and condensation, providing a durable and reliable solution. They can be controlled remotely using various electrical accessories such as geared motors and shunt opening releases. The circuit breakers are structured on a compact, sturdy metallic frame without wheels, resulting in a lightweight design. With rated power-frequency withstand voltages of up to 70kV, lightning impulse up to 170kV, and breaking capacities reaching 20kA, these breakers are built to handle demanding electrical applications. They operate at standard frequencies of 50-60Hz with a rated current up to 1250A, suitable for multiple industrial electrical environments.
