Please note size. Characteristics of Switch types Turn and Push The contacts are manually operated by turning and/or pushing. The turn- and push-function could be locked with a programmable push-pull interlock, so that e.g. turning just possible with pushed handle. DK-series Up to 48 contacts (4 each stage), up to 24 switch positions The A-series could be used, when you need switch programs up to 48 contacts or more than 12 switch positions. A-series Connection with terminal lugs With DHR-/DKR-series it's possible to get enclosed contact chambers instead to the standard-series CHR. This series includes patented lugs for easy handling of terminal lugs. CHR-/DHR-series 7,6 mm lower installation depth in opposite of Type CA4 Compared of Switch type CA4 a lower installation depth of 7,6 mm is possible. CA4N CA4N-1 Rated Thermal current from 350 to 2400 A Switches of the L-series are compact switches for higher currents up to 2400 A. They are applicated for connect or disconnect of resistiv, moderate inductive oder under no-load conditions. L-series DC-switch up to 1000 V / 20 A with snap on latching and knife contacts Operational power of 1000 V DC / 20 A combined with high short circiut protection can also be used for AC applications with low currents and voltages. Possible functions: 0 – 1, 1 – 2, 1 – 0 – 2, with max.12 contacts G20, G20S < Klicken Sie auf das Thema um dorthin zu gelangen. > < Back to the catalog directory >
