Powerpact B-Frame Circuit Breaker accessory, LV429426, offers proven performance, flexibility, and reliability. A time delay unit for the MN eliminates the risk of nuisance tripping due to a transient voltage dip lasting less than 200 ms for fixed delay units and up to 3 seconds for adjustable units. For shorter micro-outages, a system of capacitors provides temporary supply to the MN at V > 0.7 Vn to ensure not tripping. PowerPact B-frame ratings and types. Available in 1, 2, 3, and 4-pole unit mount construction & 1, 2, and 3-pole I-Line™ construction. Cost-effective fixed thermal-magnetic trip units from 15-125A up to 600Y/347 Vac. Interrupting ratings include D-18 kA, G-35 kA, and J-65 kA at 480 Vac. Unique I-Line construction mounts into Square D™ panelboards and switchboards. Designed to the same 1.5″ per pole widths as the legacy F-frame, simplifying substitution without blank fillers. Unit mount (aka, lug-lug) construction is 30% smaller in size with 25% more capacity than the legacy unit-mount F-frame design EverLink atented technology. EverLink lug connectors reduce the loosening of cables over time using a spring tension design. EverLink lugs are rated for bare use with fine-stranded conductors up to Class K. EverLink lugs are also available with unique integrated control wire terminals.
