in position. The test adapter is
ideal for convenient, rational testing
of assembled terminals.
Further helpful accessories are
available for terminals using tension
clamp technology, such as:
• Pluggable extra connections (ZZA)
• Housings for installation of
electronic components (ZBS 1)
• Pluggable fuse holder
(SIHA SIHA 3)
• Terminals various colours.152
