Solve VFD Line & Load Power Quality Problems
MTE LINE/LOAD REACTORS help keep your equipment running longer by absorbing many of the power line
disturbances which otherwise damage or shut down your inverters, variable frequency drives (VFDs), variable
speed controllers, or other sensitive equipment. They are a robust filtering solution for virtually any 6 pulse rectifier
or power conversion unit. There is no need to de-rate MTE RL reactors as they are harmonic compensated and
IGBT protected to assure optimum performance in the presence of harmonics, and are very effective at reducing
harmonics produced by inverters and drives. Standard MTE RL reactors may be applied up to 690 VAC with
compatible impedance ratings. MTE RL Reactors have higher continuous and overload ratings.
HARMONIC COMPENSATION makes MTE reactors suitable for use on either the drive input or drive output. They
are designed to carry full rated fundamental current and will also handle current and frequencies associated with
harmonics up to 50% over the fundamental. This robust design allows all MTE reactors to be used on the output
of variable frequency drives including IGBT types with switching frequencies up to 20kHz. A premium dielectric
system is designed to protect the reactor’s coils from the potentially high peak voltages and fast dV/dT which may
be experienced when used for motor protection with long leads between inverter and motor.
SINGLE PHASE - MTE three phase reactors may be applied to
single phase drives to provide transient protection as well. See
application details for correct single phase drive sizing.
EPOXY IMPREGNATION minimizes audible noise in the reactor
and enhances structural and moisture integrity.
HIGH SATURATION CURRENT RATING of MTE reactors
maximizes their surge current protection capability. MTE
reactors absorb many of
the power line disturbances
which cause nuisance trips
on voltage source units.
PRODUCT SELECTION: See MTE RL Selection Brochure or visit the MTE website at www.mtecorp.com and select
the handy >> Reactor Click Find << for complete product selection & CAD files.
TERMINALS: Terminals are standard and save installation cost by minimizing panel space. Finger-proof (IP20) terminals are provided through 45 amps. Solid copper box lugs are provided above 45 amps to 160 amps. Copper tab
type B14 or B1 flag terminals are used beyond 160 amps (see photo above).
INSTALLATION OPTIONS: MTE line/load reactors are available in a variety of enclosures. The NEMA 1 for general
protection or the NEMA 3R for weather protection.
TRANSIENT PROTECTION OPTIONS: Various voltage rated MOV transient devices may be factory installed to
reactor’s output to offer the maximum over-voltage input drive security .
Typical uses include:
