Load Break Switches
A load break switch makes and breaks load current but not fault current, which makes it the right device for sectionalising a feeder and creating a safe isolation point for maintenance.
A load break switch makes and breaks load current, but not fault current. That distinction matters: it is the right device for sectionalising a feeder and for creating a safe isolation point for maintenance, and it is the wrong device for interrupting a fault.
On a distribution network, load break switches let an operator split a feeder into sections, so a fault or a planned outage takes out one section rather than the whole run. That is the difference between a handful of customers off supply and a few thousand.
Typical applications
-
Feeder sectionalising
Splitting a long feeder so a fault or planned outage affects a smaller section of the network.
-
Maintenance isolation
Creating a visible, secure isolation point so work can proceed safely on a section of line.
-
Ring main configurations
Switching supply between alternative feed paths in a ring arrangement.
-
Load transfer
Moving load between feeders without interrupting supply to customers.
Specifications on request
Load break switch selection depends on network voltage, continuous current, the short-time withstand rating the network requires, and whether the switch is manually operated or motorised for remote control. Tell us what the switch needs to do and where it is going, and we will confirm the right unit, pricing and availability.
