FAQs
The LGS3250FAG is ideal for industrial control panels and distribution boards that require robust protection for feeders up to 250 A. Its three-pole LG-frame design with line and load terminals and metric mounting facilitates straightforward integration in new builds or retrofit projects. Its 50/60 Hz compatibility makes it suitable for global facilities and varying electrical standards.
The T185 trip type provides fixed thermal protection with an adjustable magnetic trip, enabling precise coordination with downstream devices and upstream protection. This reduces nuisance trips during motor startup and transient faults while maintaining selectivity across multiple devices in a panel. It is particularly beneficial for motor feeders and mixed-load applications in automation retrofits.
Yes, the LGS3250FAG supports higher voltage applications. It provides 85 kAIC at 240 Vac, 50 kAIC at 480 Vac, and 25 kAIC at 600 Vac. This range supports equipment protected at different voltages within a single installation, improving protection for critical loads and enabling safer, more reliable distribution in mixed-voltage environments.
This MCCB is UL Listed, CSA Certified, and CE Marked, with HACR rating noted in catalog references. These certifications verify safety, electrical performance, and regulatory compliance across North America and international markets. The combination supports global procurement, reduces compliance risk, and streamlines panel approvals for multinational projects.
Investing in the LGS3250FAG yields ROI through improved reliability, reduced downtime, and easier maintenance. The 250 A rating, precise T185 trip coordination, and high interrupt ratings protect costly downstream equipment.
