| Motor Protection Relays |
| We offer a wide range of Motor Protection Relays which prevents motor failure, caused by heat generated during long working period. Overheating occurs due to Over Current that may be due to over load condition or low voltage or phase failure or phase unbalance. 10 degree of increased temperature can reduce the 50 percent life of the motor. The protection unit is used to measure the negative sequence component leveled in the motor feeder that causes excessive negative sequence components in the motor current.
Microcontroller Based Motor Protection Unit:
Features:
- MPU can be used for wide range 1 Amp to 999 Amp
- MPU reduces inventory and maintenance
- Provides protection from Current & Voltage problem such as Single Phasing, Phase Reversal, Current Unbalance, Over load (current), Under load (current) & Over Voltage, Under Voltage
- Continuous monitoring of Current & Voltage through Auto scanner
- MPU can be directly used up to 30 Amp i.e. upto 20HP motor & for higher rating motors with external current transformer up to 1000/5 Amp can be used with wiring connection
- Software calibration & password facility straight through keys
- All protection are settable & trip time is also settable, hence can be used in various application
- Inverse time characteristics for over load
- Displays the fault condition, even if one phase is available
Applications:
- Induction Motors
- Pumps
- Blowers
- Compressors
- Crane Motor
- Conveyor Motor
- Genset Panels
- Electrical Panels
- Electrical Test Benches
- Compressor Motors
