CPP1115/02
The super-compact DC contactors of the CPP series are the smallest Schaltbau switching devices in the power class up to 200 amps and suitable for nominal voltages up to 1,500 volts. The single-pole switching devices are available as NO or NC contactors.
They are used in main and auxiliary converters of railway vehicles, but also in converters and inverters in the field of renewable energies or, more generally, in industrial environments.
Features
Small dimensions – great performance! All air gaps in the contact area are generously dimensioned. The rated insulation voltage is 3,600 volts for OV2 and 3,000 volts for OV3.
The contactor’s arc chamber is made of plastic. This is efficient and saves weight.
The CPP can switch on currents of up to 2,000 amps in the make contactor version. In the version as a break contactor, up to 850 amps. High contact forces and optimised silver contacts favour the excellent breaking capacity.
The CPP series can permanently carry currents of up to 200 amps in the NO contactor version. In the version as a NC contactor, currents of 120 amps can be carried. Connection cross-section: NO contactor 120 mm², NC contactor 35 mm², maximum ambient temperature: 70 °C. The values are achieved through high contact forces.
For 100 milliseconds, the normally open contact can carry a maximum current of 2,000 amps. The short-circuit current carrying capacity of the NC contact is 1,800 amps. This time is sufficient to trigger the short-circuit protection and prevent welding of the main contacts. The short-time current carrying capacity is supported by high contact forces and optimised silver contacts.
Two S870 series auxiliary switches are optionally available for extensive diagnostics and switching condition monitoring. The switches have robust silver or gold contacts.
