The single-pole AC and DC contactors of the C160 and C162 series are universally configurable. Cam switch elements (NO) are used as main contacts; depending on the type of current and the level of voltage, with our without permanent-magnetic blowout and arcing chambers. Auxiliary switch blocks with up to 6 auxiliary contacts are available for control or locking tasks.
Schaltbau cam contactors are compact and extremely reliable. They are used in transport technology and numerous industrial applications.
The universally configurable contactors C160 and C162 are designed for switching loads frequently. The switching elements can be replaced easily.
During switch off, an electric arc is ignited between the opening contacts. The current flows on through the ionised air. Permanent magnets drive the ionised air out of the contact zone into the arcing chamber. Here, the electric arc is extended and cooled until it goes out.
For DC voltages of up to 40 volts, a cam switch element with a permanent-magnetic blowout mechanism is to be selected. At voltages of over 40 volts, an electric arc chamber should also be used. At voltages of over 400 volts, the switching element S307 G/N with arcing chamber LK-S307 DC must be used.
The cam contactors C160 and C162 can be used in all DC applications up to 1,000 volts in which the load does not have to be switched off in both directions:
The switch state of the main contacts can be reported to higher-level control systems and devices through auxiliary contacts.
Break contacts, make contacts or combinations of these are available with the cam-operated switching elements of the S007 series. For safety-related tasks, S800 or S826-series snap-action switches can be chosen: Changeover contacts with double-break contact and mechanical positive opening operation .
The auxiliary switch blocks are installed ex-factory. Quantity and contact type are to be specified during the order.
