Phasefale MP15 Motor Protection – Plug-in Type
The MP15 is a fully automatic solid state motor protector with adjustable start delay, anti-short cycle timer and fault memory. It is suitable for all sizes and types of single and 3 phase motors.
Models for 2010 include new improved phase detection electronics and precision for greater all round motor protection in all supply situations.
Phasefale’s MP15P motor protection relays closes the motor protection gap. In an affordable and compact package, the MP15P shields motors from the damaging thermo-electric motor winding stresses that can result from.
- Phase loss
- Under voltage
- Phase imbalance
The MP15P’s advanced microprocessor-based fault detection technology responds to supply faults before they cause motor damage––unrivalled precision, Reliability and responsiveness acting on three distinct fronts:
- PHASE LOSS – The MP15P’s advanced electronics responds to phase loss in seconds, a fraction of the response time typical of thermal overload relay solutions.
- UNDER VOLTAGE / BROWN OUT – Typically not addressed by overload protection technologies, ‘brown out’ conditions result in high current / high torque winding stresses that are insidious degraders of motor life. The MP15P uniquely offers a user-adjustable under voltage trip point (nominal 75% adjustable between 60-90%), and fault-response time of less than three seconds.
- PHASE IMBALANCE – Conventional phase-imbalance protection is a ‘blunt’ instrument. Founded on star-point/voltage summation technologies, these struggle to differentiate between genuine three-phase imbalance and the waveform distortion/clipping commonly found in modern industrial facilities. Using advanced signal processing solutions, the MP15P elegantly and precisely ‘picks the difference’, thus providing incomparable phase-imbalance sensitivity and speed of response (25% nominal 15-35% adjustable. Less than three seconds response time).
