An all-round portfolio of protection devices for industrial applications, infrastructure and buildings. These offer protection in the event of overload and short-circuit, and against electric shocks in the event of direct and indirect contact. Thus people as well as plants and high-value devices are protected. Financial losses caused by the failure of systems and devices are prevented.
Flexibly Applicable and Communication-Capable 3WL air circuit breakers offer a very flexible applicability and integrated communication capability. They optimally meet the increased requirements placed upon air circuit breakers particularly with regard to the operation and monitoring of network processes in connection with electronic control systems. The quality of this range sets new standards worldwide. With only three sizes, the 3WL air circuit breakers cover a power range from 630 A to 6300 A. Featuring a 3- or 4-pole design, they are suitable for applications up to 1000 V. All models are characterized by identical design – in fixed-mounted as well as with drawable version – identical operation and identical comprehensive accessories. The particularity: In the upper performance range, the 3WL is the world’s smallest circuit breaker of its class. • Conforms to IEC 60947-2 • Rated current - 630A to 6300A • Accurate protection through microprocessor based trip unit • Unique ready-to-close interlock for maximum safety • Mechanical contact erosion indicator • Fully rated upto 55oC • Neutral 100% rated • Integrated online test facility • Unique Cubicle Bus technology • Data communication and power management options
