For some time, industrial professionals have
straddled a ‘gap’ in conventional motor protection
technologies. On the one hand lie motor overload
relays; both bi-metallic and electronic versions.
These, along with rudimentary phase-protection
relays, provide built-to-a-budget ‘bare-minimum’
protection functionalities. On the other hand lie
thermistor protection solutions; costly stator winding
thermal-averaging devices that respond to
localised motor winding thermo-electric stresses
after they occur.
What’s missing? Direct and immediate protection
against the vagaries of the power supply and system
that can stress motor windings, shorten motor life,
and jeopardise production up-time.
While ‘high-end’ electronic protection relays can
offer such protection, they are in a price-bracket
and form-factor that make them ‘unaffordable’
for smaller motors under 45 kW.
AN INDUSTRIAL DILEMMA:
While the capital cost of smaller motors might be
small, the cost of lost production in the event of a
motor burnout can be huge. The ‘gap’ is a costly
accident Zaiting to happen...
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 Zinding stresses that can result from
