What Does the D2 MPR3 Protect Against?
The D2 MPR3 is a multifunction current monitoring relay that offers robust protection against a wide range of electrical faults and operating risks, including:
- Phase Unbalance
- Phase Failure
- Phase Sequence Reversal
- Under Voltage & Over Voltage
- Overload Protection
- Dry Run Protection
These features make the D2 MPR3 suitable for demanding motor and pump environments, where a single undetected fault could lead to costly equipment damage or production halt.
Typical Applications of D2 MPR3 Relay
The D2 MPR3 relay is engineered for versatile industrial motor and pump setups, such as:
Air Conditioning & Refrigeration Compressors – Prevents phase loss or unbalance damage to motors.
Crusher Motors in Mining Applications – Shields against overload during heavy-duty material grinding.
Elevators, Lifts, Hoists & Cranes – Maintains smooth, fault-free motor operation under load shifts.
Screw Compressors & Rotating Equipment – Ensures consistent performance with dry run and voltage protections.
