The GE Multilin 350-L-P5-G5-H-E-E-N-N-1E-D-N, also cataloged as the 350-L-P5-G5-H-E-E-N-N-1E-D-N Feeder Protection System, operates as a dedicated hardware component for power distribution protection and current measurement within industrial switchgear networks.

Hardware Specifications

Profinet and EtherNet/IP Deterministic Networks

Configured for high-speed industrial operations, the protection system manages backplane bus communication velocity licenses to interface directly with deterministic network topologies. Profinet and EtherNet/IP protocol layers process cyclic data exchanges without packet collision overhead. Firmware flash compatibility ensures seamless integration during system upgrades, while I/O density scaling allows dynamic adjustment across expanding rack architectures without degrading bus cycle execution times.

Frequently Asked Questions

Q: What are the primary current input ratings supported by this feeder protection system variant?

A: The system is equipped with 5 A 3-phase current inputs and a 5 A ground current input configuration.

Q: Is this protection system capable of hot-swap operations in active switchgear racks?

A: Hot-swap capability is supported via its drawout case construction provided that auxiliary power is sequenced correctly and chassis grounding pins establish physical contact prior to signal engagement.

Field Installation Guidelines

Ensure the panel cutout and drawout case are clear of particulate contamination before inserting the relay along the designated mechanical guide rails. Secure retention latches to the specified torque limit to establish a low-impedance ground path to the switchgear chassis. Verify that ambient enclosure temperatures do not exceed the operating boundary. Route CT, PT, and communication cabling away from high-voltage AC conduits to minimize electromagnetic induction on internal metering circuits.
