circuit breakers WL vacuum 12-24KV

Product catalog summary
Overview
The document outlines the WL series medium voltage vacuum circuit breakers designed for indoor applications. These breakers utilize a separate pole technique, with each pole containing a vacuum interrupter encapsulated in resin, providing protection against impact, dust, and condensation.

Specifications
The circuit breakers are available in 12kV and 24kV versions, with rated normal currents of 630A, 800A, and 1250A. They adhere to IEC 62271-100 and CEI EN 62271-100 standards. The operating temperature range is from -20°C to +40°C.

Operating Mechanism
The breakers feature an energy-stored and free-release operating mechanism, enabling independent opening and closing operations. Remote control is facilitated by optional electrical accessories like a geared motor and shunt releases.

Applications
WL circuit breakers are ideal for medium voltage secondary distribution and MV/LV transformer substations in industrial and service sectors. They are suitable for unmanned substations without auxiliary power supply, thanks to an optional self-supplied microprocessor-based overcurrent release.

Testing and Compliance
The circuit breakers have passed type tests (heating, insulation, short-time current withstand, mechanical life) and individual tests (insulation, resistance measurement, mechanical and electrical operation) to ensure safety and reliability.

Accessories
Standard accessories include mechanical signaling devices, operation counters, and auxiliary contacts. Optional accessories include additional shunt releases, undervoltage releases, and mechanical overrides.

Diagrams and Notes
The document contains electric circuit diagrams for various components and operational states, along with notes on circuit supervision and power supply considerations for auxiliary circuits.
