SWITCH DISCONNECTORS
l
A switch disconnector is defined in BSEN60947-3 as:
“
A switch which, in the open position, satisfies the isolating requirements specified for a disconnector”
IEC 60947–3 also defines a switch and a disconnector. In general terms the definitions cover a device that is capable of making, carrying and breaking normal
circuit currents, and may also be capable of carrying, for a specified time, abnormal loads such as short circuit currents. In the open position, the device will
provide isolation and it will indicate reliably the position of the contacts.
All Crabtree switch disconnectors rated in the following table comply with BSEN60947-3 and IEC 60947-3.
