H01H51/00 - CPC Classification

Classification description:

Electromagnetic relays

Sub-classes:

H01H51/005 » {Inversing contactors } 18
H01H51/01 » Relays in which the armature is maintained in one position by a permanent magnet and freed by energisation of a coil producing an opposing magnetic field 48
H01H51/02 » Non-polarised relays 0
H01H51/22 » Polarised relays 26
H01H51/27 » Relays with armature having two stable magnetic states and operated by change from one state to the other 33
H01H51/28 » Relays having both armature and contacts within a sealed casing outside which the operating coil is located, e.g. contact carried by a magnetic leaf spring or reed 9
H01H51/29 » Relays having armature, contacts, and operating coil within a sealed casing 42
H01H51/30 » specially adapted for actuation by alternating current 10
H01H51/34 » Self-interrupters, i.e. with periodic or other repetitive opening and closing of contacts 3
