PN-2 100A safety lock

nbsp;The scope of safety locks is very wide and stretches from an electrical wiring in houses, high-rise construction, production shops and the power supplying organizations to production of the equipment, distributive and industrial electroinstallations.
Safety locks differ from other protective devices in the high settlement disconnecting ability at the minimum volume. For ensuring these high parameters, beginning from conditional current of melting, the minimum inadmissible current of an overload and finishing the maximum current of short circuit, at production the large number of indicators of quality is taken into account. 
PN-2 100A safety locks with a non-demountable fusible insert are intended for protection of electric equipment of plants and electric networks of three-phase alternating current of 380 V with a frequency of 50 and 60 Hz and chains of a direct current with a rated voltage of 220 V at overloads and short circuits.
