The electrical and thermal ratings specified are safe operating limits determined by various factors including material properties, mechanical design, and the intended operating environment. All electrical ratings are based on operation with one side in dry atmosphere and the other side in vacuum of 1 x 10-4 Torr maximum pressure. Temperature ratings for various mounting options may reduce the operating range of an assembly. All assemblies have a maximum thermal gradient of 25ºC per minute and may be damaged if this limit is exceeded.[/vc_column_text][/vc_column][/vc_row][vc_row bg_color=”#bcbcbc”][vc_column width=”1/1″][vc_column_text]Breaks are electrical isolators made of tubular materials which are composed of metal adapters brazed to both ends of a ceramic insulator. Diameters of 2.5″ or less are referred to as breaks, while those over 2.5″ are referred to as envelopes.
