ABSTRACT OF THE DISCLOSURE: A polarized electromagnetic relay with magnetic latching and sliding armature. The magnetic circuit comprises a tubular frame enclosed by two flanges, a permanent magnet with axial magnetization fitted between one of the flanges and a flux-diverter, and a cylindrical trip coil mounted on a bushing inside the frame. The other flange is fitted with a tubular sleeve made of ferromagnetic material coaxially surrounding a part of the moving armature with a uniform radial air gap interposed. The axial overlapping distance of the armature by the sleeve in the latched position of the relay is greater than the thickness of the flange and/or than that of the frame. The invention find its application in a trip release for electric circuit breaker.
