Frequently Asked Questions about 350-E-P1-G1-H-E-M-C-N-3E-D-N
What is the drawout construction option of the GE Multilin 350 feeder protection series 350-E-P1-G1-H-E-M-C-N-3E-D-N device?
The 350-E-P1-G1-H-E-M-C-N-3E-D-N feeder protection relay includes the drawout construction option (D). This option allows the user to completely eliminate the need to rewire after testing. With this option, the user does not need to disconnect communication cables (Ethernet fiber, copper, RJ45) or open switch the gear door before removing the device from the case. The 350-E-P1-G1-H-E-M-C-N-3E-D-N is also very small and compact. May relays can be mounted adjacent to one another in close proximity on a medium voltage panel. If the depth of the compartment is an issue then the 350 has the ability to use reducing collars.
How does the Multilin General Electric 350 feeder protection device 350-E-P1-G1-H-E-M-C-N-3E-D-N allow for preventative maintenance?
The G1-H-E-M-C-N-3E-D-N allows the operator to be able to track and monitor the relay’s exposure to harsh or extreme operating conditions by tracking high ambient temperatures and by giving an alarm in this situation. The user can schedule routine maintenance or upgrade activities. This feature simply allows the user to become more aware of the deterioration of electronics over time due to harsh conditions. This 350-E-P1-G1-H-E-M-C-N-3E-D-N is optimal to protect, control, and manage a variety of feeders and their associated applications.
