LV433334 Schneider Electric Molded Case Circuit Breakers (MCCB)

Out if stock but available for backorder.

Schneider Electric LV433334 is a Moulded Case Circuit Breaker (MCCB) within the NSX100HB2 sub-range, designed for lug connection and equipped with three poles. It features protection functions including long-time protection (L), short-time protection with fixed time delay (S0), and instantaneous protection (I), alongside phase unbalance or phase loss detection. The rated current is 25A, with a rated insulation voltage (Ui) of 800 V. Protection settings are adjustable for L from 0.5 to 1 x In and for S0 from 5 to 13 x Ir, while I is fixed at 425A with specific trip conditions for phase unbalance; a >30% unbalance triggers a time delay of 0.7s during starting and 4s during normal operation. The rated impulse voltage (Uimp) stands at 8 kV, with a frame current rating of 100 AF. Mechanical durability is noted at 20,000 operations without load, and electrical durability at 10,000 operations (690Vac; In/2) and 5,000 operations (690Vac; In) with load. The rated voltage for phase-to-phase connections is 690 V. All three poles are protected, utilizing a Micrologic 2.2M (LI) interchangeable electronic trip unit, and it falls under utilisation category A.
