Design with blowout magnets and large extinguishing chamber for a particularly high breaking capacity.
C360 – AC and bi-directional DC contactors up to 1,500 volts for railway applications
Compact single-pole NO contactors for AC and DC (bidirectional) up to 1,500 volts rated insulation voltage. Making current up to 2,500 amps; conventional thermal current up to 500 amps; short-time current up to 3,000 amps
The bi-directional DC contactors of the C360 series switch high powers in a small space. With a making capacity of up to 2,500 amps, the compact switchgear is suitable for applications with high inrush current or high capacities.
All versions can continuously conduct up to 500 amps. In the event of a short circuit, 3,000 amps, can even flow for one second without the contacts welding. The contactor therefore maintains its full function in order to disconnect high power ranges if necessary up to 500 amps and up to 1,500 volts – irrespective of the current direction. The full bidirectionality is important for many applications in railway vehicles. Many design variants are also available, matched to a wide range of applications, e.g. as the main contactor in traction and auxiliary converters of battery and hybrid vehicles or as an isolating contactor in battery circuits with high currents.
Features
Compact dimensions – high rated insulation voltage Ui up to 1,500 volts
Small dimensions – big performance! Nevertheless, all the air gaps in the contact area have been generously dimensioned. The rated insulation voltage is 1,500 volts. The arc chamber of the C360 is made of plastic. This is efficient and saves weight.
Making capacity Icm up to 2,500 A, bistable design available
The C360 can switch on a current of up to 2,500 A (monostable design in a horizontal installation position; L/R = 0 ms).
A PWM controller regulates the coil current and ensures low-bounce switch-on as well as a low and constant holding power. High contact forces and solid silver contacts benefit the making capacity.High conventional thermal current Ith up to 500 A
All versions of the C360 can continuously carry up to 500 A. (Cross-section of the connections: 185 mm2, maximum ambient temperature: 85°C; terminal heating: +65 kelvin). The value is reached through very high contact forces.
High short-time current-carrying capacity Icw up to 3,000 A (1 s)
The C360 can carry a current of up to 3,000 A for one second without the contacts welding. This is enough time for the short circuit fuse to trip. The short-time withstand current rating is based on high contact forces and optimised silver contacts.
Full bidirectionality – reliable disconnection of high performances
All versions of the C360 can reliably disconnect high currents and voltages, irrespective of the current direction.
These properties are achieved in the A and K versions through the special arrangement of blowout magnets and arcing chambers, high contact forces and generously dimensioned clearances in the contact aera.
Use as the main contactor in traction and auxiliary converters of battery and hybrid vehicles or as an disconnector in battery circuits with high currents
Traction contactor for battery or hybrid vehicles:
- Main contactor in combination with a precharging contactor in the traction converter of locomotives, railcars and trams
- Main contactor in combination with a precharging contactor in the auxiliary converter of locomotives, railcars and trams
- Disconnecting contactor for battery-powered functions in locomotives and multiple units
- Contactor for battery-powered functions in passenger coaches
- Deep discharge protection for batteries in emergency power supplies
Auxiliary switch with mirror contact function
Series C360 contactors are equipped with auxiliary contacts with mirror contact function. The mirror contact function complies with the standard DIN EN 60947-4-1 Annex F.
The mirror contact function means that the NC contact of the auxiliary contact must not be closed at the same time as the NO main contact.
By selecting this option you finish the configuration.
