Power contactor CF

motorelectromagneticAC

Schaltbau’s new, highly modular CF series begins with a compact 3-pole AC power contactor for loads up to 600 A and 3000 V for inverter-fed alternating current drives with higher frequencies. One special feature are the newly developed switching chambers. These can be universally configured as NO, NC or in combination as a change-over. An efficient electronic economy circuit reduces power consumption as well as heat loss and saves costs. CF contactors can be adapted in many ways. The high variance makes the devices interesting for use in many different applications. The innovative switchgear is equally ideal for new projects and modernisation. They can successfully replace cam contactors that have proven themselves over many years. DC variants will follow. Features - Compact dimensions – high performance range: 3,000 V AC / 3x 600 A, frequencies up to 400 Hz - Innovative application-dependent arc chamber design – configurable as NO, NC or changeover contact - High thermal continuous current 300 A or 600 A through parallel connection of two main contacts each and a high rated short-time withstand current up to 4,000 A - 4 auxiliary switches for diagnosis and switching status monitoring - Low energy consumption and low heating thanks to sophisticated coil saving circuit
