Eaton E2R320WS29 Specialty MCCB - 3P 2000A 600V
Part Number: E2R320WS29
Quick Summary
The Eaton E2R320WS29 is a specialty molded case circuit breaker designed for mining electrical protection. Maintenance teams often wrestle with bulky MCCBs that slow trips and complicate wiring in harsh underground and surface environments; this unit delivers robust protection with a compact footprint. While the data sheet lists Certifications as Not Applicable, mining installations typically require UL/CSA/CE compliance per regional codes, so verify local requirements. By combining a 3-pole 2000 A 600 V rating with a 110–240 VAC shunt trip, this breaker supports high-current equipment while reducing downtime and maintenance complexity. It also complements broader Eaton E2 protection strategies for scalable, reliable mine-site protection and predictable maintenance planning.

Feature: 3-pole 2000 A 600 V thermal-magnetic BKR protection. Benefit: Enables dependable interruption of high-current faults in large mining equipment, reducing arc flash risk and equipment damage. Application: Suitable for conveyors, crushers, and mobile mining equipment where high fault currents are common. Feature: 110-240 VAC shunt trip. Benefit: Allows remote or automatic tripping for enhanced safety and faster fault response, improving operator protection during remote operations. Application: Remote shutdowns and safety interlocks in underground and surface mining lines. Feature: LSI 4000-18000. Benefit: Provides a wide range of load shedding and trip characteristics to match dynamic mining loads, minimizing nuisance trips and optimizing uptime. Application: Spin-down conveyors and milling stations with variable inrush. Feature: 3P configuration with 20 in length, 18 in height, 19 in width and 125 lb weight. Benefit: Predictable footprint simplifies cabinet planning and replacement in retrofit projects. Application: Equipment enclosures and control panels with strict space constraints. Feature: Not Applicable certifications noted in data. Benefit: Emphasizes the need to confirm regional regulatory approvals locally; supports tailored compliance planning rather than assuming universal listings. Application: Regional mining deployments where local UL/CSA/CE requirements govern installation. Feature: Compatibility with Eaton E2 family offerings. Benefit: Reduces spare-part diversity and streamlines procurement for multi-site mining projects. Application: Large-scale mine electrification programs seeking standardized protection hardware.

FAQs
Plan for a three-pole mounting arrangement with a 20 x 19 x 18 inch footprint and a 125 lb weight. Ensure adequate enclosure space, ventilation, and clearance for wiring and heat dissipation. Use proper mounting hardware and verify panel compatibility with Eaton E2 family MCCBs to simplify retrofit and spare parts stocking.
The shunt trip accepts 110-240 VAC and enables remote or automatic tripping when a control signal is applied. Wire the coil to an appropriate control circuit or safety system to enable rapid fault isolation, improve operator safety, and support interlocks with other protective devices in the mining system.
The data for this model lists Certifications as Not Applicable. In practice, verify UL/CSA/CE or regional approvals with Eaton and local authorities before installation. Compliance should be confirmed per your project’s jurisdiction, as mining sites often require specific listings for electrical protection equipment.
Expect a footprint around 20 in by 18 in by 19 in with a weight of about 125 lb. Plan panel cutouts, mounting rails, and cable management accordingly. Ensure the enclosure can tolerate mining environment conditions and that the wiring clearances meet NEC/IEC guidelines for service access and heat dissipation.
The high current rating and robust thermal-magnetic protection reduce nuisance trips and potential equipment damage, lowering downtime. Remote trip capability enhances safety and reduces operational risk. Although maintenance frequency depends on duty cycle, standardized Eaton components simplify spare parts management and service expertise across multiple mine sites.
