Honeywell 104001-0-F0-K0-10-5-0 Motor Protection Relay Unit

Module Feature

104001-0-F0-K0-10-5-0 is a dedicated motor protection relay manufactured by Honeywell for industrial three-phase motors. It provides full-range protection including thermal overload, locked rotor, earth fault, phase unbalance, phase loss, reverse phase and overcurrent protection. This relay supports motor start supervision, power metering, sequence of event logging and fault oscillography. Multiple digital input and relay output channels are reserved for equipment status acquisition, trip and alarm output. It is equipped with Ethernet and serial communication interfaces to exchange data with SCADA, DCS and HMI systems. Widely used in water treatment, petrochemical and power plant MCC cabinets to protect pumps, fans and conveyors.

Working principle

The Honeywell relay continuously samples three-phase current and voltage signals from CT and VT. The internal CPU runs thermal simulation model and protection algorithms. When operating conditions exceed preset thresholds, the relay activates trip contact to cut off motor power, meanwhile recording fault waveform and timestamp. It monitors startup duration to prevent winding damage during motor acceleration. Real-time electrical data and alarm messages are uploaded to upper control system via communication links.
