Siemens Type WL low voltage metal-enclosed switchgear is designed, tested and constructed to provide superior power distribution, power monitoring and control. At the heart of the Type WL low voltage switchgear is the world class Siemens WL breaker. The Type WL low voltage switchgear assembly (lineup) consists of one or more metal-enclosed vertical sections. Each vertical section consists of up to four individually enclosed breakers or auxiliary compartments which are designed to provide superior modularity and uniform height. Included in each switchgear lineup are various components such as WL breakers, instrumentation and control equipment, transformers, relays, three-phase bus work and all internal wiring, connectors and other supporting components.
