MECHANICAL INSTALLATION
Drawout case
The 750/760 is packaged in the standard GE Multilin SR-series arrangement, which consists
of a drawout relay and a companion case. The case provides mechanical protection for the
drawout portion and is used to make permanent electrical connections to external
equipment. Where required, case connectors are fitted with mechanisms, such as
automatic CT shorting, to allow the safe removal of the relay from an energized panel.
There are no electronic components in the case.
