From the universally configurable series C152, C153 and C154 result 2, 3 and 4 pole contactors for AC and DC with cam switching elements of the S306 series for 160 or 200 A of continuous current.
The main contacts can be configured as make contacts, break contacts or as combinations of both. For arc quenching at high loads, electric arc chambers can be used; and for DC voltages over 400 volts, arcing chambers with permanent-magnetic blowout should be used.
The switch state of the main contacts can be reported to higher-level control systems and devices with up to 4 auxiliary contacts.

Features

Robust design, simple maintenance

The universally configurable contactors C152, C153 and C154 are designed for switching loads frequently. The switching elements can be replaced easily.

DC versions with blowout magnets and arcing chambers

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 switching 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.

Unidirectional DC applications of up to 1,000 V

The multi-pole cam contactors C152, C153 and C154 can be used in all DC applications up to 1,000 V in which the load does not have to be switched off in both directions:

  • Railway technology
  • DC drives of machinery
Economy resistor or optional electronic economy circuit

In order to protect the coil of the contactor from excessive heating, a resistor is connected in series with the coil after switch-on.

Optionally, an electronic economy circuit can be chosen. This supplies the required pick-up current for the activation. The current is then regulated down by the electronic economy circuit to the a significantly lower holding current. As a result, the coil becomes less hot and the control power is reduced considerably. The module is attached directly under the contactor.

Up to 4 auxiliary contacts in auxiliary switch blocks

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.
