The RXLG Series Aluminum Housed Wirewound Braking Resistor is a high-performance industrial dynamic braking resistor engineered and manufactured by RST Electric, a professional resistor supplier with over 10 years of dedicated R&D and production experience.Aluminum Housing Resistor is specially developed to solve the common defects of traditional open wire resistors and ceramic tubular resistors, such as frequent overheating, weak vibration resistance and short service life under continuous dynamic braking conditions.
Adopting an integrated extruded aluminum alloy shell as an all-in-one heat sink and a high-temperature ceramic core wrapped with high-stability alloy resistance wire, the RXLG braking resistor features a compact structure, excellent heat dissipation performance and strong anti-shock capability.
Its power range covers 60W to 2000W, with resistance values from 0.1Ω to 10KΩ. It supports two resistance tolerances (±1% / ±5%) and multiple temperature coefficient options. Three ingress protection grades (standard IP20, optional IP54 & IP65) are available to adapt to diverse working environments.
All products comply with CE and RoHS international certification standards. Widely matched with variable frequency drives (VFD), servo motors, elevators, cranes, UPS power supplies, welding equipment and renewable energy power generation systems, RXLG series resistors are ideal for dynamic braking, regenerative energy dissipation and load testing. We support full OEM & ODM customization on power, resistance, terminal type and installation dimensions, serving global automation equipment suppliers and system integrators.

Grooved Extruded Aluminum House, Compared with flat aluminum casings, the grooved design expands the heat exchange area by 42%. It realizes passive natural heat dissipation without auxiliary cooling fans, effectively reducing internal hot spots and avoiding local overheating during long-time continuous operation.
1. Ceramic Core Winding Structure. The high-temperature inorganic ceramic core firmly fixes the alloy resistance wire. Even under long-term equipment vibration, the resistance wire will not shift or loosen, keeping resistance deviation within the standard tolerance range and ensuring stable electrical performance.
2. Pre-punched Mounting Base. Pre-reserved standard mounting holes on the bottom shell enable quick installation on equipment cabinets. Close contact installation improves heat conduction efficiency by more than 30%, maximizing the heat dissipation advantage of the aluminum shell.
3. Multiple Optional Terminals. Three terminal types (screw terminal, flying lead, custom connector) are provided to match the wiring habits of different automation integrators and equipment manufacturers, improving on-site wiring efficiency.
1. Excellent Heat Dissipation & High Power Density
2. Strong Mechanical & Environmental Resistance
3. Easy & Flexible Installation
4. Reliable Electrical Safety.
5. Complete Specification Coverage
6. Long Service Life
7. Flexible Customization
Aluminum Housing Resistors are widely used in industrial automation, power electronics, lifting machinery, new energy and other fields. The core function is dynamic braking and regenerative energy dissipation.
1. Variable Frequency Drives (VFDs)
2. Power Supplies & UPS
3. Motor Control & Automation
4. Welding Equipment
5. Cranes & Elevators
1. Daily Spot Check, Check if the shell is discolored and if the terminals have abnormal odor when the equipment starts up. Stop use immediately if the resistor overheats abnormally.
2. Monthly Routine Maintenance, Clean dust and oil dirt in the aluminum heat dissipation grooves. Dust accumulation is the main cause of resistor overheating failure.
3. Quarterly Deep Maintenance, Cut off the power supply, tighten terminal screws, and use a multimeter to test the actual resistance value. Replace the resistor in time if the resistance exceeds the tolerance range.
4. Long-term Idle Storage Maintenance, Store products in a dry and ventilated warehouse. Power on and run for 30 minutes every 3 months to remove internal moisture and prevent insulation performance degradation.
We select 4 typical global customer cases with real pain points, solutions and measurable improvement data to show product performance in actual working conditions.

All RXLG series resistors pass 100% full factory inspection before delivery, including resistance test, high voltage withstand test and thermal imaging detection, to ensure qualified products.
A: No. IP20 grade only prevents large solid debris and has no waterproof and moisture-proof capability. For outdoor, damp or splash-prone environments, please choose customized IP54 or IP65 sealed resistors to avoid internal short circuit caused by water vapor.
A: There are four main reasons:
① The surrounding space is blocked, resulting in poor heat dissipation;
② Dust accumulates and clogs the aluminum heat dissipation grooves;
③ The actual instantaneous braking power exceeds the rated power of the resistor;
④ Loose terminals cause excessive contact resistance.
A: Yes. Series and parallel connection are supported. Our professional technical team can provide targeted series-parallel wiring solutions according to your required power and resistance parameters to realize combined high-power load.
A: We provide 12-month global warranty under correct installation and normal operating conditions. Meanwhile, we offer lifelong free technical guidance for parameter selection, installation and fault elimination.
A: Definitely. We can customize rated power, resistance value, tolerance, IP grade, terminal type, mounting size and shell color according to drawings or requirements. OEM and ODM services are fully available.
A: The normal operating ambient temperature ranges from -55℃ to +200℃, adapting to high-temperature workshops and low-temperature outdoor environments in different regions.
