Powercon's MEIS Switchgear exceeds ANSI/IEEE Standard C37.20.3, with no exceptions taken to any requirement of the ANSI/IEEE. These switches are available with either electrical or mechanical operators. When used in conjunction with fuses they will afford overload, short circuit and disconnect services. This switchgear is used:

• On the primary of transformers for their protection and isolation.
• For the protection and isolation of single circuit systems.
• For the protection and isolation of multi-circuit systems.
• For automatic transfer schemes where their ratings are not exceeded.
