Electric differential switch of 40A 300 mA, high immunization type "F", 2 poles, to protect people from isolation or derivation problems in electrical installations or elements. For use in domestic, tertiary and industrial sectors.
Tripping occurs when there are residual sinusoidal alternating currents as well as type A currents, in addition to residual currents with multiple frequencies, as a result of non-linear and distorted loads, such as those produced by frequency inverters (frequency converters). Type F differential switches are capable of detecting multiple frequencies up to 1kHz.
The sensing, evaluating, and tripping functions for these switches are not voltage dependent. Tripping is not affected by low value DC residual currents up to 10mA. The type F residual current circuit breaker has a delayed trip feature to avoid unwanted trips. Another feature is the high immunity against current waveforms of 8/20us (up to 3 kA). This switch is installed like any differential switch. Complies with EN 61008 and EN 62423 standards.
These differentials are electromagnetic in operation, which prevents the safety function from being lost in the event of voltage variations. Only with the bypass in the active phase does the differential trip occur. Being electromechanical in operation, it provides a wide operating voltage range (230/400 VAC), which implies a high degree of immunity to input voltage variations, and likewise, the safety function is not lost in the event of failure. of power in the neutral.
