  • WiNmaster2 power circuit breakers are a new generation of air circuit breakers having modular construction to offer a truly global product platform meeting IEC, ANSI and UL standards.
  • A line of three and four pole devices ranging from 630 to 3200 amp in two basic frames with fault interruption ratings of up to 65kA.
  • A design offering a unique combination of high fault current withstands ratings, short fault interruption time and zone selectivity.
  • The device includes the new state-of-the-art MicroPro2 intelligent trip unit that enables the circuit breaker with the latest technology for system safety, reliability, measurement, relaying and communications using the Modbus, Profibus or device net protocol.
  • Breaking capacity up to 65kA; common accessories across the range; modular construction with most compact dimensions; high mechanical & electrical operating life; intelligent micropro releases with communication protocol (modbus / profibus) RS485.
  • Termination options - horizontal / vertical / front; breaker operating trucks for easy handling of breakers; interchangeable trip units for same thermal ratings; maximum of 6NO/6NC potential free contacts for customer wiring.
