Circuit Breakers Explained
Eaton Specification Sheet - LG3500WX04Y02
Feature: High amperage rating and broad voltage tolerance. Business Impact: The 500 A amperage rating and 600 Vac capacity tolerate industrial loads and fault events without nuisance trips, enabling reliable engine-generator protection across a wide range of genset outputs. Application: Suitable for engine-generator sets delivering up to 451 kVA at 600 Vac (and 181 kVA at 240 Vac generator ratings), making it ideal for medium to large power plants, data centers, and standby systems. Feature: Fixed thermal and magnetic trips (T186). Business Impact: Fixed trip technology provides fast, predictable fault clearance and consistent coordination with upstream protective devices, reducing arc flash risk, equipment wear, and downtime. Application: Essential for engines with high inrush and variable load profiles in manufacturing lines and critical facilities. Feature: Three-pole, L-frame, complete breaker design with line/load options. Business Impact: The three-pole configuration, compact L-frame, and optional line or load terminals simplify installation, improve wiring clarity, and enable easier retrofits in existing switchgear without major enclosure changes. Application: Ideal for engine-generator protection in compact enclosures and retrofit projects. Feature: Certifications and regulatory alignment. Business Impact: UL 489, CSA, and IEC 947-2 certification ensure code compliance, product traceability, and safer integration in diverse geographic regions. Application: Suitable for global deployment in facilities requiring strict electrical protection standards. Feature: Generator-specific functionality and rugged construction. Business Impact: Reverse feed capability and engine-generator class ratings help you manage standby and emergency power confidently, while the Series C complete breaker with L-frame supports durable performance under rugged industrial conditions. Application: Used in standby power systems and industrial facilities with generator-driven loads. Feature: Warranty and lifecycle considerations. Business Impact: A one-year warranty from purchase or 18 months from shipment reduces risk and supports predictable maintenance planning. Application: North American procurement programs seeking reliable post-sale support for critical power protection equipment.

FAQs
LG3500WX04Y02 is designed for standard engine-generator enclosures using a three-pole, L-frame molded case protection. It supports optional line or load terminals and fixed trips, simplifying installation in common switchgear footprints. When selecting a replacement, evaluate enclosure space, terminal configuration, and panel clearances to ensure a clean retrofit with minimal field wiring and downtime.
Key specs include a 500 A amperage rating, 600 Vac voltage rating, three-pole configuration, and a generator rating range up to 181 kVA at 240 Vac, 361 kVA at 480 Vac, and 451 kVA at 600 Vac. The T186 fixed trip provides thermal and magnetic protection, while the Series C frame and L-frame orientation optimize mounting stability and upstream coordination.
Yes, LG3500WX04Y02 provides reverse feed functionality as part of its protection features. This supports engine-generator configurations where power can be routed back toward the utility during transfer operations. Always confirm compatibility with your transfer scheme and wiring sequence to ensure safe energization control.
LG3500WX04Y02 carries UL 489, CSA Std C22.2 No. 5, and IEC 947-2 certifications, indicating compliance with North American and international electrical protection standards.
