The Signal-Cam Controller NU 1 is used as a signal and annunciation switch in HV systems. This rugged switching device has cam discs made of insulation material that can be set at 10° intervals. The Signal-Cam Controllers are designed to permit series assembly, which can be operated simultaneously.The DC Contact is used for signalling and annunciation applications. The snap-action mechanism prevents slow contact opening when the plunger is operated slowly. Quenching of the arc that occurs with DC is supported by two-capacity permanent magnets.These are arranged so that the polarity can be ignored when connecting +/- cabling. However, the polarity of the quenching magnets must be noted when installing the contacts to prevent the magnets adversely affecting each other. Contacts in four different colours are available for polarity identification of the magnets when fitted.The contact may only be installed on non-magnetisable materials with screw, etc. made of non-ferrous metal.The self-cleaning silver contacts are designed for low switching frequency, low currents and voltages. Gold coated contacts can be supplied (approx 0,2μ), less than 42 Volt required. The screw connection M3.5 at the side is suitable for 2 conductors max. 2,5 mm². The plug-in connection at the top 4.8 x 0.8 mm DIN 46247.Several contacts can be plugged on the top of each other and operated jointly. The plug-Tips terminals are then only accessible on the top unit. The contacts can be provided with shock protection to DIN VDE 0106 Part 100.
