IEM Switchboards can be custom designed or utilize a standard configuration to meet specific dimensional and electrical requirements. They can include fully integrated component options from leading manufacturers, including automatic transfer switches, TVSS, distribution transformers, and PLC or relay-based transfer schemes. Circuit breakers and fusible switches can be grouped or individually mounted. Indoor and outdoor electrical switchboard enclosures are available in a wide range of durable color finishes.
