Product parameter

The 350 relay is a member of the 3 Series family of Multilin relays. This protective device is used to perform primary or back-up circuit protection on medium or high voltage feeders or transformers and downstream protection for utility and industrial switchgear. The 350 can be used for a wide variety of protection applications in power systems such as HV/MV or MV/LV transfomer
protection or capacitor bank protection.
The basic protection provided by this relay includes multiple phase, ground, and neutral time and instantaneous overcurrent elements for coordination with upstream and downstream devices. Additionally, the device provides essential feeder control features such as cold load pickup blocking, 2nd harmonic blocking, breaker failure, synchrocheck and autoreclose.
The robust 350 streamlines user work flow processes and simplifies engineering tasks such as configuration, wiring, testing, commissioning and maintenance. This cost-effective relay also
offers enhanced features such as diagnostics, preventative maintenance, arc flash mitigation and security

Application field

• Primary protection and control for MV and HV utility and industrial overhead or cable feeder applications
• Protection for distribution transformers of various sizes and voltage levels
• Back-up protection for various HV application and capacitor bank protection
• Advanced control applications including Cold Load Pickup, multi-shot recloser and multiple settings groups
• Protection, control and monitoring of LV Incoming feeder providing flexible communications and eliminating the need for auxiliary equipment
• Protection against corrosion and humidity required for harsh environments
