H01H83/144 - CPC Classification

Classification description:

Protective switches, e.g. circuit-breaking switches, or protective relays operated by abnormal electrical conditions otherwise than solely by excess current operated by unbalance of two or more currents or voltages, e.g. for differential protection with differential transformer

Sub-classes:

H01H2083/146 » {Provisions for avoiding disadvantages of having asymetrical primaries, e.g. induction of a magnetic field even by zero difference current} 4
H01H2083/148 » {with primary windings formed of rigid copper conductors} 11
