How can the electronics in SwitChek connect safely to a power system?
Firstly, SwitChek is designed to withstand Cat III 500V installations in accordance with IEC 61010 . This means that it is suitable to withstand overvoltages sometimes experienced on 500V switchboards. The method for achieving this performance is by the use of sufficient creepage and clearance distances as well as using componentry certified to provide this level of protection. Secondly, should an internal fault develop within SwitChek, the SwitChek Interface incorporates 1A, High Rupturing Capacity (HRC) fuses rated for installations up to 50kA fault levels. This means that the fuses will interrupt power to the fault prior to severe SwitChek damage. Thirdly, SwitChek is contained in a double insulated, fire retardant, polycarbonate dust proof and water proof (IP66) enclosure. It is mechanically robust.
