RR Switchgear range of compact On Load Changeover Switches are manually front operated four pole switches which helps to save space in panel boards resulting in low costing of the same. These comprise two On Load Switch Disconnectors, which are coupled together and are mechanically interlocked with common ou going. These are used in low voltage distribution circuits and motor circuits and at places where continuity of supply is necessary for switching from the main supply to an alternate source of supply and vice versa. All On Load Changeover Switches are capable of making, carrying, and breaking currents under normal circuit conditions, which may include operating under overload conditions and also carrying currents under specified abnormal circuit conditions such as short circuits for a specified time. Range: Current range 40 Amp. to 3150 Amp. in nine frame sizes in Four Pole 415V AC 50 Hz. Conformity to Standard: Conforms to IEC-60947-1 & 3, IS/IEC-60947-3 Specification: Rated Operating Voltage [V] - 415 Rated Insulation Voltage [Ui] - 1000V Rated Frequency [Hz] - 50 Utilization Category - AC 23A [63A-320A], AC 22A [400A-3150A] Rated Impulse Withstand Voltage [Uimp] - 10 kVChangeover Switches
