1. General Description

The BHA series Load Break Switch, incorporating proven flat-chamber arcing technology, can perform a wide variety of switching functions in medium-voltage distribution systems. They are the result of more than 50 year's experience in development and manufacture of load break switch by SHONEVAC. The simple, low-maintenance and highly economic indoor load break switch in the BHA series have a proven service record, with hundreds of thousands of units installed and operating on a wide range of systems.

The BHA load break switch comply with the requirements of IEC 60694 (EN 60694) and IEC 60265-1 (EN 60265-1). Additionally, selected variants are available, complying with IEC 62271-105 (EN 62271-105).

2. Main applications

BHA series load break switc is designed for use in indoor medium- voltage switchgear systems. They have a making capacity and are suitable for switching:

• load currents
• currents in ring mains
• transformers, cables and overhead lines.

BHA load break switch is the reliable and economic solution for refurbishment and maintenance programs, extensions, renewal or upgrading of personnel protection.

3. Special features

• high reliability and long service life
• low operating cost due to long periods between maintenance procedures
• space-saving design
• high switching capability
• low operating torques
• suitable for use in in harsh climatic conditions
• ideal as substitute for older load break switch
• load break switch-fuse combination to IEC 62271-105 (EN 62271-105) available.
