The LHL26125 is a Square D LH-frame two-pole 125-ampere molded case circuit breaker manufactured by Schneider Electric as part of the Q4 Legacy circuit breaker product line. Built on a 400A frame with high interrupting capacity, this unit mount breaker is rated for 600 Vac / 250 Vdc. It delivers interrupting ratings of 65 kAIC at 240 Vac, 35 kAIC at 480 Vac, and 25 kAIC at 600 Vac, plus DC ratings of 50 kAIC at 125 Vdc and 50 kAIC at 250 Vdc. The thermal-magnetic trip unit provides LI (Long-Time and Instantaneous) protection with an adjustable magnetic instantaneous trip range of 625A to 1250A for precise overcurrent coordination. Designed for unit mounting with lugs (line and load), this two-pole breaker is ideal for single-phase and two-phase applications in switchboards, panelboards, and motor control centers. The LHL26125 accepts wire sizes of (1) 1 AWG-600 kcmil or (2) 1 AWG-250 kcmil Al/Cu, measures 11.0 x 4.0 x 5.84 in, and weighs approximately 20 lbs. Compliant with UL 489 and CSA C22.2 No. 5.1 standards, the LHL26125 provides dependable overcurrent protection for industrial, commercial, and institutional electrical systems. As a member of the Square D Q4 Legacy product family, this breaker offers long-term reliability and seamless integration with existing Square D electrical distribution infrastructure, making it an excellent choice for both new installations and replacement applications.
