HYDRA Motor Run Capacitors
Source HYDRA motor run capacitors for industrial motors, pumps, fans, compressors, HVAC equipment and machinery maintenance through Apexon Supply. The products reviewed in this collection include metallized polypropylene film capacitors from the HYDRA MLB MKP, MKB MKP, MDB MKP and MS MKP families, with individual models covering different capacitance values, AC voltage classes, dimensions, mounting arrangements and connection configurations.
For replacement work, selecting a capacitor by appearance alone is not sufficient. Industrial buyers should compare the complete HYDRA model designation together with capacitance, voltage class, frequency, physical dimensions, mounting, connection method and any applicable safety or environmental requirements. Apexon supports B2B buyers with part-number verification, specification review and sourcing coordination for current, replacement and difficult-to-find HYDRA capacitor requirements. Availability and commercial terms remain subject to confirmation for each inquiry.
HYDRA Motor Run Capacitor Overview
The HYDRA products represented in this collection are primarily MKP motor run capacitors used in continuous AC motor applications. MKP refers to metallized polypropylene dielectric construction. Reviewed models include capacitors intended for motor run and phase-shifting duties, while selected models are also described for power-factor correction applications.
The available product pages demonstrate that HYDRA capacitors cannot be treated as one interchangeable specification range. Even capacitors with similar capacitance values may differ in voltage-life classification, case size, lead length, mounting method, protection class or connection arrangement. For this reason, replacement selection should begin with the original part number and nameplate data whenever possible.
HYDRA Capacitor Product Families

How to Select a HYDRA Replacement Capacitor
For an industrial replacement, start with the complete marking on the original capacitor. Two cylindrical capacitors may look similar while having different electrical or mechanical requirements. Before ordering, confirm the following information against the equipment documentation or original component:
- Complete manufacturer part number: include every series identifier, capacitance value, voltage designation and suffix.
- Capacitance: verify the required value in µF rather than selecting by case size.
- Rated AC voltage and class: reviewed HYDRA models use different voltage and service-life classifications, so the complete rating must be compared.
- Frequency: confirm the equipment requirement and the frequency marked on the capacitor.
- Capacitance tolerance: several reviewed products specify ±5%, but this should still be confirmed for the required part number.
- Dimensions: check case diameter, height and available installation clearance.
- Mounting: verify threaded stud size, fixing arrangement and orientation.
- Connections: compare flying leads, cable length, terminals and any protective cap or enclosure arrangement.
- Safety and environmental requirements: confirm the required safety class, standard, climatic category, protection rating and operating conditions where applicable.
Do not substitute a different capacitance value simply because the voltage rating or housing looks similar. If an exact model is unavailable, any proposed alternative should be evaluated against the original electrical, mechanical and application requirements before use.
Industrial Applications
HYDRA motor run capacitors in this collection are associated with continuous-duty and phase-shifting applications in AC motor systems. Reviewed product information identifies uses in pumps, industrial fans and ventilation systems, compressors, HVAC equipment, motor-driven machinery and other industrial or commercial motor circuits.
Specific models also reference additional uses. For example, the MLB MKP 4/400I/E589 is described for motor run and power-factor correction circuits, while the MDB MKP 5/400II/E1321 is described for phase shifting and power-factor correction in pumps, fans and HVAC compressor motors. These application references are model-specific and should not be assumed to apply to every HYDRA capacitor.
Replacement and Difficult-to-Find HYDRA Capacitor Sourcing
Older machinery often remains productive long after the original capacitor part number becomes difficult to identify or source through normal purchasing channels. Apexon Supply supports industrial buyers, maintenance teams, OEM service departments and MRO procurement organizations that need help locating HYDRA motor run capacitors by exact model number or technical specification.
For an existing HYDRA part, Apexon can review the original MPN, capacitor label, datasheet and equipment information before sourcing. Where the requested original product can be sourced, the quotation can be based on that identified requirement. Availability, production status, quantity, packaging, lead time and origin should be confirmed at the time of quotation rather than assumed from a historical part number or online listing.
If an exact model is obsolete, discontinued or otherwise difficult to obtain, a technically suitable alternative may be considered only after the relevant specifications have been compared. Important points can include capacitance, rated AC voltage, voltage-life class, frequency, tolerance, dimensions, mounting, terminals or cable configuration, safety class, climatic category and equipment-specific requirements. An alternative should not be presented as equivalent solely because it has the same capacitance value.
Providing a clear photograph of the original capacitor label is especially useful when the installed component has an older marking, partial part number or unfamiliar suffix.
