## Summary description

Electrical motor run capacitor Rebel MKSP-8 with 1 µF capacitance and 450 V rated voltage (model URZ3957). Designed for use in AC electric motors and related control circuits to improve phase shift and motor performance. Paper-in-oil/polypropylene metallized construction typical for MKSP series, suitable for replacement or repair of motor capacitor assemblies.

## Long description

Rebel MKSP-8 1 µF 450 V motor run capacitor (model URZ3957) is an electrical component intended for use in AC electric motors and associated control circuits. It provides a steady capacitance of 1 microfarad and a rated voltage of 450 volts, designed to support phase shift and stable motor operation. The capacitor uses a paper-in-oil/polypropylene metallized construction typical for MKSP series devices, offering electrical characteristics suitable for replacement or repair in motor capacitor assemblies.
Advantages
The capacitor delivers a defined capacitance value with a 450 V voltage rating appropriate for many single-phase and polyphase motor applications. Its MKSP-8 construction combines paper-in-oil and metallized polypropylene layers to achieve reliable dielectric behavior and stable electrical performance. The compact form factor allows installation in confined motor housings or control panels where space is limited. The device is intended for direct replacement of compatible motor run capacitors, facilitating repairs without extensive modification of existing circuits.
Suitable for
 Single-phase AC motors requiring run capacitors
 Motor repair and service workshops
 Replacement in motor capacitor assemblies and control boxes
 Applications needing a small 1 µF, 450 V run capacitor
Key specifications
 Capacitance: 1 µF (microfarad)
 Rated voltage: 450 V AC
 Dielectric / construction: paper-in-oil with metallized polypropylene (MKSP-8 type)
 Intended use: motor run capacitor for AC motors and control circuits
 Form factor: compact radial/module shape suitable for motor housings and control panels
How to use
Install the capacitor in accordance with the motor manufacturer’s wiring diagram and local electrical codes. Before installation, disconnect power and discharge any existing capacitors to avoid electric shock. Mount the capacitor securely in the motor housing or control panel, ensuring correct polarity if specified and proper clearance from heat sources. Connect terminals to the motor or control circuit using appropriately rated wiring and secure fasteners. After installation, restore power and verify motor operation and current draw to confirm correct phase shift and performance.
Usage recommendations
Use this capacitor as a direct replacement only when capacitance and voltage ratings match the original component. Regularly inspect the capacitor for signs of swelling, leakage, corrosion, or degraded terminals and replace if any deterioration is observed. Follow safety guidelines for handling and disposal of capacitors and consult a qualified electrician for installation in industrial or high-voltage environments.
