LOW VOLTAGE MITSUBISHI SWITCHGEAR
Low-voltage Switchgear Type AL-P
Highlights
Heat stress analysis of the switchgear structure has led to a heat-resistant design in which circuit breakers up to 5000A are self-cooled (i.e.cooling fans not required).
All components, such as current transformers, voltage transformers, relays and meters, are made of the highest quality materials.
AL-P low-voltage switchgear are designed with the benefit of Mitsubishi’s vast switchgear and circuit breaker production experience of in excess of one hundred thousand panels over last 50 years.
The reduced number of parts reduce the chance of failure.
Partitions between compartments and an automatic shutter system completely isolate live parts.
The pressure relief device which is installed optionally releases hot gas upwards in the event of an internal arc fault for operator’s safety.
Control switches are installed at a height appropriate for easy viewing and operation.
Installation and testing duration are considerably reduced as the switchgear is tested and adjusted in the factory and then delivered as a complete unit.
Panels with main circuit and control cable entry from either top or bottom are available.
The AL-P is readily combined with Mitsubishi Electric‘s Motor Control Center (MCC). The combined arrangement has advantages such as compact size and a simplified overall structure. As the MCC utilizes a double-front design, a larger number of motor starter units can also be accommodated. The AL-P is the perfect complement for Mitsubishi’s MCCs. (Further information regarding Mitsubishi’s MCCs can be found in a separate publication.)
