3WL Air Circuit Breakers

Description

3WL Air Circuit Breakers

With the 3WL circuit breakers, just three sizes cover a performance range of 630 A to 6300 A. Available as a 3 or 4-pole version, they are suitable for use up to 1150 V. All models – whether fixed-mounted or withdrawable – are characterized by the same design, the same operation and the same comprehensive accessories. Special features: In the high-end performance range, the 3WL air circuit breakers are the smallest circuit breakers in their class worldwide.

Features

• Coordinated communication concept using the PROFIBUS DP or MODBUS, ranging from 16 A to 6300 A with 3VL molded case circuit breakers and 3WL air circuit breakers
• The high level of modularity of circuit breakers and accessories allows easy retrofitting of all communication components
• Significant additional benefits for the switchgear due to the possibility of linking up external input and output modules to the circuit breaker-internal CubicleBUS of the 3WL
• Innovative software products for parameterization, operation, monitoring, and diagnostics of circuit breakers, both locally or via PROFIBUS DP, MODBUS or Ethernet/Intranet/Internet
• Complete integration of the circuit breakers into the solutions of Totally Integrated Power and Totally Integrated Automation CubicleBUS of the 3WL air circuit breaker
• Innovative software products for parameterization, operation, monitoring, and diagnostics of circuit breakers, both locally or via PROFIBUS DP, MODBUS or Ethernet/Intranet/Internet
• Complete integration of the circuit breakers into the Totally Integrated Power and Totally Integrated Automation solutions

Application

• As incoming feeder, distribution, coupling and outgoing feeder circuit breakers in electrical installations
• For switching and protecting motors, capacitors, generators, transformers, busbars and cables.
• The AC devices are available as circuit breakers and non-automatic air circuit breakers. DC devices are available as non-automatic circuit breakers.
