Products and services
- Neutral Grounding Resistor (NGR/NER) Power resistors used for transformer and generator grounding applications to provide safe fault current paths and system stability in electrical distribution networks. Sold to utilities, power plants, and industrial end users.
- High Resistance Grounding (HRG) Grounding systems that limit ground fault current while maintaining system stability for sensitive industrial applications. Used by industrial facilities requiring continuous operation during single line-to-ground faults.
- Dynamic Braking Resistor (DBR) Power resistors used with variable frequency drives (VFDs) and servo drives to safely dissipate regenerative energy during braking, enabling controlled deceleration of motors. Used in industrial machinery, transit, and crane control applications.
- Motor Control Resistor (MCR) Resistors used to control torque and speed of AC and DC wound-rotor motors by adjusting circuit resistance through slip rings. Commonly used in mining and heavy industrial applications with squirrel cage and slip-ring induction motors.
- Harmonic Filter Resistor Resistors used in RLC circuits for passive harmonic filtering to reduce electrical distortions in power systems caused by non-linear loads such as VFDs, arc welders, and computer equipment.
- Load Bank Resistor Resistive load banks used for generator and UPS testing to verify power generation equipment performance under controlled load conditions.
- Discharge Resistor Resistors placed in parallel with high-voltage supplies to safely discharge stored electric charge in capacitors or batteries during equipment servicing or repair.
- Neutral Grounding Cabinet Enclosed cabinets containing neutral grounding resistors along with current/voltage transformers, disconnect switches, surge arrestors, and capacitors for grounding large generators.
- Ground Fault Protection Relays Protection relays used in conjunction with grounding systems to detect and respond to ground fault conditions in electrical systems.
- Grounding Transformers Transformers used as part of grounding systems to provide neutral points for system grounding in various electrical configurations.
- Custom Resistor Monitoring Monitoring systems for resistor banks to track performance and status of power resistor installations.

MegaResistors competitors and assessment
Company assessmentBroad incumbents
- TE Connectivity: Diversified electronic component manufacturer serving industrial, rail, and energy markets with power resistors and related passive products; overlaps with MegaResistors in industrial-grade resistor applications but is not a power-resistor specialist.
- Vishay Intertechnology: Global passive component giant with a power resistor portfolio (including wirewound and braking resistors); much larger scale and broader catalog, competing on availability and price rather than custom build-to-order engineering.
- ABB: Major VFD manufacturer that also sells branded braking resistors and offers grounding solutions; both a competitor (resistors) and customer ecosystem (drive OEMs that drive resistor demand) for MegaResistors.
Direct peers
- Stackpole Electronics: Produces a broad line of through-hole and power resistors including wirewound and braking types; broader catalog offering but overlapping in the VFD braking and industrial power resistor categories.
- Post Glover Resistors: Long-established manufacturer of neutral grounding, dynamic braking, and harmonic filter resistors with comparable cross-reference coverage across major drive brands, directly competing for the same utility and industrial customers.
- Powerohm Resistors: US-based manufacturer of power resistors including braking, neutral grounding, load bank, and harmonic filter resistors—essentially the same product mix and end markets as MegaResistors, making it the closest head-to-head competitor.
- HVR International (High Voltage Resistors): Specializes in high-voltage and high-power resistors including neutral grounding and discharge resistors, with comparable testing capabilities and a similar industrial customer base.
- Danotherm Electric: Danish manufacturer specializing in power resistors for VFD braking, neutral grounding, and load banks; a like-sized European peer competing for global industrial customers on similar custom-built resistor banks.
- Ohmite Manufacturing Company: Specialist in power and precision resistors (wirewound, edgewound, thick film) serving industrial, medical, and aerospace markets—a broader resistor portfolio but overlapping in the high-power, custom-engineered segments.
- Riedon Inc. Manufacturer of precision and power resistors including wirewound and braking types for industrial and rail applications, with comparable custom-engineering services and direct sales motion.
