DescriptionGeneral Electric Multilin 737 Feeder Protection Systems
OverviewMultilin™ 735/737 is a microprocessor based relay used to perform primary circuit protection on distribution networks at any voltage level. Protection features include three phase timed overcurrent, phase instantaneous overcurrent, ground timed overcurrent, and ground instantaneous overcurrent.Each protection element can be selectively enabled by the front panel dial settings. Flexible settings and selec-table curve shapes enable accurate coordination with other devices. Installation and maintenance costs are lower when the 735/737 is used instead of the 8 separate overcurrent protection devices it has been designed to replace.The 735/737 feeder relays are being discontinued. You may still purchase these relays until December 29, 2017. The suggested replacement device is the Multilin 8 Series. Customers can easily upgrade to the Multilin 850 feeder protection system using the Retrofit Kit.
Key BenefitsMinimize replacement time - Draw-out construction Simplify testing - Built in simulation features Access information - via Modbus RTU
Typical ApplicationsPrimary circuit protection on distribution networks at any voltage level Backup protection for transformers and transmission lines
