CF – Multipole AC power contactors for loads up to 600 A and 3,000 V
The Schaltbau CF series stands for multi-pole AC contactors with configurable switching chambers and a rated operating voltage of up to 3,000 volts for 300 amps or 600 amps with NO or NC switching chambers.
CFS3-15-181818000000N-AM-41
The CF series from Schaltbau is an extremely modular switchgear concept. Variants with 1 to 6 main contacts are available. If required, these can be individually configured as normally open or normally closed contacts. Mixed configurations are also possible. The contact system is suitable for DC with full bi-directionality and AC up to 400 Hz. This means that different requirements can be flexibly realised. The high switching functionality and reliability allow practical and economical use. The patented and exclusively permanent-magnetic arc-handling enables a compact design. This saves space and reduces weight. The combination of innovative technology, compactness and versatility makes the CF series particularly suitable for use in railway and industrial applications. Thanks to its unique modularity, the product family comprises a large number of different design variants, tailored to a wide range of applications.
Features
Newly developed, innovative switching chambers
- The switching chambers can be configured as normally open contacts, normally closed contacts or in combination as changeover contacts. A mixed configuration of normally open and normally closed contacts is also possible
- Main contact configuration: DC uni- or bi-directional, AC up to 400 Hz
- Effective arc handling – no critical current range and only minimal wear on the main contact system thanks to permanent magnetic blowout
- High making capacity, for normally open and normally closed contacts alike
- Monostable and bistable drives available. Bistable drives only require energy for the switching process. This reduces heat dissipation
- Modular, compact, low total cost of ownership (TCO)
Compact dimensions – high power range
- Minimum dimensions for length, width and height in this performance class. The shorter »S« versions have one drive, the longer »W« versions have two drives.
- 3,000 V AC / 400 A max., DC uni-/bi-directional, AC up to 400 Hz. The rated insulation voltage is 3,600 V max.
Application-dependent, innovative arc chamber design with ceramic, plastic or metal extinguishing elements
The modern arc chamber design is optimised for use in different applications. The efficient arc chamber inserts are available with ceramic, plastic or metal extinguishing elements:
- Ceramic: DC for high switching requirements
- Plastic: DC or AC for low switching requirements
- Metal: AC for high switching requirements
4 auxiliary switches for diagnosis and switching status monitoring
CF contactors are equipped with a maximum of 4 auxiliary contacts. The contact status is mapped via snap-action switches with positive opening. S870 series snap-action switches with a changeover contact, positive opening and silver or gold contacts are used. The auxiliary switches are also mirror contacts in accordance with IEC 60947-4-1, Annex F.
Low energy consumption and low heating thanks to sophisticated coil saving circuit
The pull-in behaviour is controlled by a PWM controller independent of the coil voltage and temperature applied. This ensures a safe and low-bounce switch-on. In holding mode the PWM controller regulates the coil current. This significantly reduces power consumption and heating. At the same time the reliability of the contactor is increased.
Easy maintenance
- Tool-free inspection of the main contacts
- Tool-free replacement of the arcing chamber inserts
- Simple replacement of individual switching chambers thanks to modularity
