FAQs

LG3500S02 uses an L-frame design and Series C J-Frame configuration, with a compact 5.48 in footprint per side. It supports standard MCCB mounting in compatible panels and enables straightforward retrofits with a three-pole configuration. For best results, verify panel cavity clearance, bus bar alignment, and rear shunt wiring clearances before installation to ensure reliable operation.
The breaker is rated 500 A and 600 Vac with a fixed thermal, fixed magnetic trip type (T186). It features a three-pole design and a reverse protection function. This combination provides precise overcurrent protection, fast fault interruption, and protection against reverse power flow, which is critical in generator and transfer-switch applications.
Yes. The unit’s engine-generator class with a rear shunt release (12-24 Vac/dc) and left pigtail supports remote tripping and integration with generator start/stop logic. Its UL Listed, IEC Rated, and CSA Certified credentials help meet industry and regional requirements while delivering reliable protection during generator start-up, load transfer, and fault conditions.
LG3500S02 carries UL Listed, IEC Rated, CSA Certified, and UL 489 compliance. These certifications validate safety, performance, and interoperability with global electrical codes. For manufacturers and integrators, this reduces certification risk, eases cross-border procurement, and supports audits and quality programs in regulated environments.
The MCCB comes with comprehensive datasheets and time-current curves, aiding accurate protection coordination and life-cycle planning. Benefits include reduced downtime from reliable fault interruption, lower calibration and maintenance needs due to fixed thermal/magnetic trips, and streamlined procurement through certified compliance and standardized series C components that fit existing infrastructure.
