Taking quality as our prime importance, we are engaged in manufacturing, supplying, exporting and trading Motor Protection Relay . Ideal for motor protection, these relays are manufactured using reliable hardware with special algorithms, which allows to calculate the tripping time. Continuously monitors the three phase currents to build the thermal replica, which is used to protect the motor against thermal overloads, these relays are appreciated for accurate measurements and thermal memory. Features: Accurate measurements Thermal memory Dimensional accuracy Other Details: Selectable Thermal Trip Time characteristics Class - 10A, 10, 20 and 30 Pre-alarm at 105 % of Im by Potential Free Output Contacts Fault records up to Previous 999 faults and 20 Previous On-Board faults with Date and Time stampings IncrementDecrement Key and ModeSet key in front facia Operational and Type Nature of Fault indications through OLED Communication through Modbus protocol with RS-485 Port EnableDisable option for Earth Fault, Under Current, Locked Rotor, Phase Unbalance Protection Various Models with Current ratings Dimensions in mm: 70X75X109 (WXHXL) Operating Temp: 0c to +60c Auxiliary Power Supply: 85-275V ACDC Trip Accuracy: As per IEC 947-4-1Trip Class 10A, 10, 20, and 30 Pick-Up Accuracy: +- 12.5% Specifications: Thermal Over Load Protection: Over Load Current Setting Range 2.0Amps 96.0Amps in 4 ranges as explained in SL.13 Trip Time Characteristics Class 10A, 10, 20 &30 as per IEC 947-4-1 Pre-alarm at 105 % of Im by One set of Potential Free output Contacts Thermal Memory Provision Earth Fault Protection: Earth Fault Current Setting Range10% to 50% of Im, in steps of 1% (20% - Factory Set) Trip Time Delay 0.1Sec to 5.0Sec in steps of 0.1Sec (0.1Sec - Factory Set) EnableDisable Option Phase Unbalance: Unbalance Current Setting Range 10% to 50% of Im, in steps of 1% (40% - Factory Set) Trip Time Delay 0.1Sec to 5.0Sec in steps of 0.1Sec (2.0Sec - Factory Set) EnableDisable

Prok dv’s make Microcontroller Based Motor Protection Relay PD-MMPR-303 uses the state-of-the-art Microcontroller based measurement techniques for providing protection for Motors up-to 75HP. The comprehensive protection features of the relay make it ideal for Motor protection. The heart of the relay is microcontroller based reliable hardware with special algorithms to calculate the tripping time. The relay continuously monitors the Three Phase Currents to build the thermal replica of the Motor. This thermal replica is used to protect the Motor against Thermal over Loads.The Microcontroller Based Motor Protection Relay does not require external Current Transformer (CT) for its operation for within the bandwidth of Im ranges. The three phase R, Y and B cables are made to pass through the CT hole which is in the relay. The built in CT’s takes care of stepping down of the Currents to the required level. The stepped down three phase Currents are continuously monitored by the relay to detect any abnormal behavior of the Motor and to make tripping decision. Specification Accurate and Real Time TRUE RMS measurements Motor Rated Current (Im) Selection by means of Pot meter with markings Earth Fault Setting provided by means of Pot meter with markings Selectable Thermal Trip Time characteristics Class - 10A, 10, 20 & 30 I > Thermal over load above105 % of Im - provided through visual led indication Provided the Thermal replica for motor overload condition Continuous monitoring of Motor IDLE/Stop, COLD, WARM, HOT, I> & Various Fault status through visual LED indication Various Models with Current ratings Compact and Reliable Manual TEST / RESET Facility
