Out if stock but available for backorder.

Schneider Electric LV433591 is a Moulded Case Circuit Breaker (MCCB) within the NSX250HB2 sub-range, designed for lug connection and equipped with three poles. It features comprehensive protection functions including L (Long-time protection), S0 (Short-time protection with fixed time delay), I (Instantaneous protection), and G (Ground fault protection), alongside additional protections for phase unbalance or phase loss, locked rotor, under-load (under-current), and long start scenarios. The rated current is 220A with a rated insulation voltage (Ui) of 800V. Protection settings are adjustable, with L protection ranging from 0.5 to 1 x In, S0 protection from 5 to 13 x Ir, I protection fixed at 3300A, and G protection from 0.4 to 1 x In with specific time delays for various conditions. The rated impulse voltage (Uimp) stands at 8 kV, with a trip current rating of 220 AT and a frame current rating of 250 AF. It boasts a mechanical durability of 20,000 operations at no load and an electrical durability of up to 10,000 operations at 690Vac with half load, and 5,000 operations at full load. The rated voltage for phase-to-phase connections is 690 V. The trip unit type is a Micrologic 6.2E-M (LSIG) Interchangeable Electronic, offering measurement functions for current, voltage, power, energy, demand, THD, and more, within the utilisation category A.
