Out if stock but available for backorder.

Schneider Electric LV429961 is a Moulded Case Circuit Breaker (MCCB) with embedded earth leakage protection, part of the NSX100B Vigi sub-range. This 4-pole device features lug connection type and offers thermal protection (overload), magnetic protection (short-circuit), and earth leakage protection (Vigi). It has a rated current of 80A, with a rated insulation voltage (Ui) of 800V. The protection settings are adjustable for over-current from 0.7 to 1.0 times the rated current (In) and have a fixed short-circuit pickup current of 640A. The rated impulse voltage (Uimp) is 8kV, and the residual current sensitivity is adjustable between 30mA and 10A. The trip current rating is 80 AT, with a frame current rating of 100 AF. Mechanical durability is rated at 50,000 operations at no load, and electrical durability is rated at 50,000 operations at 440Vac with half the rated current (In/2) and 30,000 operations at 440Vac with the rated current (In). The rated voltage (AC) phase-to-phase is 690V, with all four poles protected. The trip unit type is TMD Interchangeable Thermal-Magnetic, adjustable, and the time delay for tripping is adjustable between 0 and 800ms. It falls under utilisation category A.
