NBSe BFL Series Residual Current Circuit Breaker Electromagnetic Type RCD

Product Specification

NBSe BFL Series 2P 100A Residual Current Circuit Breaker,rcd protected circuits

1. APPLICATION

BFL series 2-pole differential protection switch, electromagnetic, for protection of people against insulation / derivation problems in electrical installations or elements. For use in domestic, tertiary and industrial sectors.
Made of fire resistant plastic material and high impact capacity.
Class of use "AC" and "A" (Immunized), and can be used in any installation and are especially recommended in the case of presence of distorted intensities due to the presence of harmonics and voltage peaks, that is why it is recommended, apart from the usual applications, their use in machinery and industrial electrical panels.
This type of differential is of electromagnetic operation, without auxiliary power supply, which allows not to lose the safety function in case of voltage supply variations or loss of the neutral conductor, only with the derivation in the active phase the differential shot. Being electromechanical, it provides a wide range of operating voltage (typical between 6 and 415V), which implies a high degree of immunity to variations in the input voltage, and likewise, the safety function is not lost before the power failure in the neutral.
