FAQs
LG3500S03 is designed for three-pole generator protection with line and load terminals included, simplifying wiring during retrofit or new installations. The TA602LD terminals support reliable connection to feeder cables, while the 12-24 Vac/dc shunt trip enables remote shutdown signals. Ensure appropriate enclosure space for its 7x11x13 inch footprint and verify compliance with UL, IEC, and CSA standards before commissioning.
LG3500S03 uses a T29 trip type with a 12-24 Vac/dc shunt trip option. The shunt trip allows remote tripping through a low-voltage signal, enhancing safety for generator startup/shutdown sequences and enabling automatic isolation during faults. Wired to a compatible control circuit, it reduces response time and improves personnel safety during maintenance or emergencies.
Yes. LG3500S03 is specified as a three-pole LG-frame MCCB with TA602LD terminals. It includes both line and load terminals, simplifying installation and reducing field wiring complexity. This compatibility supports quick integration into existing switchgear or control cabinets, while maintaining secure, code-compliant terminations for reliable operation.
LG3500S03 carries UL Listed, IEC Rated, and CSA Certified markings. These certifications indicate adherence to recognized safety and performance standards, supporting regulatory compliance, customer audits, and cross-border deployments. They provide confidence in safe operation under typical industrial conditions and facilitate procurement through established certification traceability.
The 500 A, three-pole LG-frame MCCB provides robust protection with precise trip coordination, reducing unplanned outages and delaying equipment wear. Line/load terminal inclusion streamlines installation, while the remote shunt trip option enables faster fault isolation. Collectively, these features contribute to reduced downtime, lower maintenance costs, and improved overall plant reliability.
