Selling Policy 25-000 - Distribution and Control Products and Services
The 250 A amperage rating in a three-pole LG frame delivers robust protection for heavy loads, reducing unplanned downtime and avoiding costly equipment damage, which translates to higher line efficiency for manufacturing lines. With an 100 kAIC interrupt rating at 240 VAC, 65 kAIC at 480 VAC, and 35 kAIC at 600 VAC, your motors and feeders are safeguarded against fault currents across typical industrial distributions, enabling safer startup sequences and lower nuisance trips during short transients. The trip type T185 provides a precise balance between thermal and magnetic protection, allowing adjustable magnetic trip to tailor responses to motor inrush and inductive loads—improving uptime and extending panel life. Line and load terminals with metric mounting support fast, vibration-resistant installations in control panels, minimizing commissioning time for machine builders. The LG frame is HACR rated and compatible with Series G accessories, offering predictable coordination and simplified maintenance planning. CE Marked, UL Listed, and CSA Certified credentials reinforce compliance, while the 80% rating supports stable performance in variable supply conditions. This MCCB is well-suited for data centers, packaging lines, and machine control panels where reliability and safety are paramount.
