AC Line Reactor, 3-Phase: 240V-600V, 2297 μH

Hubbell Acme Electric offers a three-phase line reactor designed to guard against voltage drops and surges while extending motor and solid-state component life. Rated across a broad voltage spectrum (240V to 600V), this unit emphasizes nuisance-tripping reduction and surge current suppression. With a 2297 μH inductance rating and a current capacity aligned with typical motor drives, it provides a balanced solution for mixed-load environments where reliability matters.
AC Line Reactor, 3-Phase: 240V-600V, 2757 μH

Also from Hubbell Acme Electric, this line reactor emphasizes higher inductance (2757 μH) for more aggressive filtering in systems with sensitive electronics or demanding drive profiles. Suitable for 3-phase equipment operating near the upper end of voltage ratings, the unit aims to minimize nuisance trips and protect motors from spike currents while promoting longer life of electronics and drives.
Allen-Bradley 3 Phase Line Reactor

This Allen-Bradley offering is positioned as an OEM-grade line reactor, commonly used in industrial control panels and motor drive applications. The listing notes that the item is used and in working condition, indicating a potential option for cost-conscious projects where replacement parts must meet functional requirements without new packaging. Engineers should verify compatibility with exact motor specifications and control schemes before integration.
3-Phase Reactor

From MTE, this 3-phase reactor presents a robust chassis with substantial weight, suggesting suitability for larger industrial drives and equipment where thermal management and mechanical durability are critical. With dimensions listed as 14 x 13 x 11 inches and a 58.83 lb weight, it targets applications demanding a solid, rugged solution capable of handling continuous duty in challenging environments.
RADWELL Verified Substitute 3-Phase Reactor

RADWELL markets this product as a verified substitute for a 3-phase line reactor used with TCI Trans Coil components. Marketed as a replacement option with compatibility in mind, it targets maintenance and retrofit scenarios where exact OEM compatibility is required but new parts are preferred for reliability and lead-time reasons. The listing emphasizes 480V operation and a 3% impedance rating with 16A current capacity.
MTE RL-08002 3-Phase Line Reactor

The MTE RL-08002 model highlights 3-phase operation across 50/60 Hz with a 600V rating and an 80-amp capacity. This configuration suits medium-to-large industrial drives, where reliable line-side protection and current shaping contribute to smoother motor starts and reduced electrical stress on drives and downstream components.
GBWIRUT 1321-3R18-B 3-Phase Line Reactor

The GBWIRUT listing covers a 3-phase line reactor with a 1.5 mH inductance, 18 A rating, and 690V maximum. It is presented as a replacement for Allen-Bradley OEM parts, indicating compatibility across common control environments. Prospective buyers should confirm the exact impedance, voltage, and form factor to ensure precise fitment in existing panels.
Buying Guide: Key Purchase Considerations
- Impedance and inductance: Line reactors come in a range of impedance values measured in percent and inductance in microhenries (μH) or millihenries (mH). The chosen reactor should align with the drive or motor impedance requirements to balance inrush control, motor starting torque, and overall system response.
- Voltage range and current rating: Verify that the reactor supports the system voltage (240V, 480V, 600V, etc.) and the continuous operating current. Undersizing can lead to overheating or insufficient protection; oversizing may add cost and size without proportional benefit.
- Application type: Consider whether the reactor is for motor drives, soft starters, VFDs, or general protection. Some models emphasize nuisance-tripping reduction, while others prioritize spike suppression or longevity for solid-state devices.
- Condition and source: OEM-grade new parts provide the latest specifications, while refurbished or “used” listings may offer cost savings but require careful verification of performance and reliability. For critical equipment, validated replacements from trusted brands are recommended.
- Physical footprint and compatibility: Check dimensions, mounting options, and terminal arrangements to ensure fit within electrical panels or enclosures without obstructing other components or compromising cooling.
- Certifications and standards: Look for CE markings or other regional compliance marks that match the installation location. Certifications can impact warranty, safety compliance, and maintenance planning.
- Lead time and availability: In retrofit projects, availability and delivery timelines can influence project schedules. Verified substitutes may offer quicker options if exact OEM parts are unavailable.
In selecting a 3-phase line reactor, engineers should compare inductance, impedance, voltage handling, and current capacity across candidates while accounting for the specific drive topology, motor type, and protection goals. For high-demand environments, prioritizing models with higher inductance and robust thermal design can yield improved drive smoothness and longer component life. Always validate electrical compatibility with the existing panel, wiring, and control strategy before finalizing procurement.
