Out if stock but available for backorder.

Schneider Electric LV433476 is a Moulded Case Circuit Breaker (MCCB) within the NSX250R sub-range, designed for lug connection and equipped with three poles. It features thermal protection for overload scenarios and magnetic protection for short-circuit conditions. The rated current for this device is 250A, with a rated insulation voltage (Ui) of 800 V. Protection settings are adjustable, offering over-current protection from 0.7 to 1.0 times the rated current (In) and short-circuit pickup current settings adjustable between 5 to 10 times In. The rated impulse voltage (Uimp) stands at 8 kV, with a trip current rating and frame current rating both at 250 AT and 250 AF, respectively. This MCCB boasts a mechanical durability of 20,000 operations at no load and an electrical durability of 10,000 operations at 690Vac with half the rated current (In/2), and 5,000 operations at 690Vac with the rated current (In). It operates at a rated voltage (AC) for phase-to-phase connections of 690 V, protects three poles, and utilizes a TMD interchangeable thermal-magnetic trip unit that is adjustable. The utilisation category for this MCCB is A.
