Moulded case circuit breakers Ex9M

  • Ex9M moulded case power breakers are devices conforming to IEC/EN 60947-2. They are intended for varying applications in the sector of residential and office premises, commercial and administrative centres but also for highly demanding industrial applications. These circuit breakers are supplied with breaking capacities Ics=Icu ranging from 36 up to respectable 150 kA for all system sizes. Ex9M1 TM circuit breakers, system size 1, cover the range of nominal current from 16 to 125 A. At present, they are provided in the basic three-pole version. Four versions with varying breaking capacities are provided: Ex9M1S 36 kA, Ex9M1N 50 kA, Ex9M1H 100 kA and Ex9M1P 150 kA. They are provided with thermomagnetic releases with gradual regulation of reduced current Ir ranging from 0.8 to 1.0 In and with a firm short-circuit release Ii with value 10 x In. Beside the actual device, the basic scope of supply also includes fastening bolts and interphase barriers for potential connecting by non-isolated busbars. Ex9M2 TM circuit breakers, type size 2, are intended for applications with nominal currents ranging from 125 to 250 A. The basic scope of supply includes a 3-pole version. Also here, four versions with varying breaking capacities are provided: Ex9M2S 36 kA, Ex92N 50 kA, Ex9M2H 100 kA and Ex9M2P 150 kA. They are fitted with thermomagnetic releases with gradual regulation of reduced current Ir ranging from 0.8 to 1.0 In and with step-adjustable short-circuit release Ii ranging from 5 to 10 x In. The basic scope of supply includes the actual device as well as mounting bolts and interphase barriers. Ex9M3 TM circuit breakers, type size 3, are intended for applications with nominal currents ranging from 250 to 400 A. The basic scope of supply includes a 3-pole version. Also here, four versions with varying breaking capacities are provided: Ex9M3S 36 kA, Ex9M3N 50 kA, Ex9M3H 100 kA and Ex9M3P 150 kA. They are fitted with thermomagnetic releases with gradual regulation of reduced current Ir ranging from 0.8 to 1.0 In and with step-adjustable short-circuit release Ii ranging from 5 to 10 x In. The basic scope of supply includes the actual device as well as mounting bolts and interphase barriers.
