Box with fuses 6Ya.004U2

Fuses are installed in block covers, therefore, any attempt to get to them, you will definitely open or remove them and, thereby, break the supply voltage circuit. PPVR ARS series allows breaking the circuit at rated current, as it is equipped with arc chutes. PPVR ARS series is a combined device: fuse + load switch + disconnector, having small dimensions, installed directly on the current - carrying bus, which makes it possible, in comparison with the use of circuit breakers, to significantly reduce the dimensions of the cabinet (shield), as well as reducing the consumption of materials and components (cable, contact holders, etc. ).

When performing any work in the load circuits, PPVR of the APC series provides a visible power failure, that is, it meets the requirements of regulatory documents on electrical safety rules when working on electrical installations.
