[Product Positioning]
REF610C11LCLR is ABB RELION ® The feeder protection relay in the 610 series belongs to the core interlayer equipment of ABB substation automation system. Model interpretation: REF610 is a feeder protection relay series, C represents the 60Hz version, 11 is the basic functional level (Basic), and LCLR is the hardware/communication/power configuration code. This device integrates multifunctional protection, measurement monitoring, fault recording, and multi protocol communication into a single compact panel mounted chassis, which is a digital integrated alternative to traditional electromechanical relays and independent protection devices. It is mainly used for the protection of incoming and outgoing feeders in distribution substations with resistance grounding and firm grounding power systems, and is also suitable for marine and nearshore environments. It has been certified by DNV.

[Core Function]
This device simultaneously undertakes tasks such as feeder protection, transformer protection, motor protection, capacitor bank protection, measurement monitoring, and sequence control. Built in dual processor architecture: one processor is dedicated to ultra fast protection algorithms (with a trip time of less than 25 milliseconds), while the other processor manages communication, HMI interaction, and data recording, without preempting resources. The protection function blocks are independent of each other, each with its own set of fixed values and data records, and do not affect each other. In addition to protection, measurement, control, and status monitoring, it also provides rich PLC programmable logic functions, which can integrate the automation and sequential logic control required for substation automation into one device, greatly reducing the need for on-site hard wiring.
Protection Function (Basic Level, Complete Configuration)
Overcurrent protection: Three phase non directional overcurrent (50/51), with low set values using timed or IDMT inverse time characteristics, high set values using timed or instantaneous characteristics, and instantaneous stages using timed or instantaneous characteristics. Support 15 optional IDMT inverse time curves to ensure selective coordination with upstream fuses.
Ground fault protection: Non directional ground fault protection (50N/51N), with low set values using timed or IDMT characteristics, and high set values using timed or instantaneous characteristics. Suitable for effective grounding, resonant grounding (arc suppression coil), and low resistance grounding networks.
Thermal Overload Protection (49): Three phase cable thermal overload protection, supporting cable thermal overload model (TOL3Cab), with thermal model accuracy of ± 2% of full scale.
Voltage protection: overvoltage (59), low voltage (27).
Unbalance protection (46): Current imbalance protection.
Circuit breaker failure protection (50BF): backup protection.
Automatic reclosing (79): Supports 1-3 times of automatic reclosing and has the function of checking synchronization and no voltage. The pickup and trip signals during the overcurrent and ground fault protection stages initiate the arc protection trip and do not initiate the reclosing.
Arc protection: Two lens sensors can be optionally equipped for arc detection, automatically adjusting the reference level according to the background light intensity, and can also receive detection signals from other relays. The arc protection action time is ≤ 25ms, fast enough to beat most contactor welding times.
Measurement function
Measure three-phase current, zero sequence current, three-phase voltage, zero sequence voltage, frequency, active power, reactive power, power factor, and electrical energy (kWh/kvarh). Support demand value calculation. Supports pulse counting input (7 pulse counting input ports). Display electrical quantity information as a single value. Measurement accuracy: Current/voltage ± 0.5%, thermal overload ± 2%.
Fault recording
Built in interference recorder (fault recording module), with a recording time of up to 80 seconds, triggered by one or more internal or external signals. It can record four analog channels and up to eight user selectable switch channels, with adjustable sampling rate. Non volatile storage can store up to 100 event codes with time stamps, setting values, waveform data, waveform data of the last five events with time stamps, automatic reclosing times, and protection start/trip times.
I/O Configuration (REF610 Basic Type)
Analog input: 4 precise current inputs (rated 1A/5A, software optional), supporting 3 voltage inputs (63/110V optional).
Digital input: 2 electrically isolated switch inputs (expandable to 5), with a current consumption of 2-18mA.
Digital output: 8 programmable normally open NO trip relays+1 self-monitoring output relay, a total of 9 outlet relays. The output contact function can be freely configured as needed, with a minimum pulse length of 40 or 80 ms, and the power output contact can be configured as locked.
All channels are provided with electrical isolation, which can effectively suppress common mode spike interference of the frequency converter.
The CT ratio (M80/M83) only affects the measurement value and waveform data, and the protection function operates independently without being affected by CT ratio parameters.
