Low-Voltage Systems
Fused Switch-Disconnectors
Safe breaking and easy replacement with fused switch-disconnectors
Reliability in low-voltage distribution depends on safely breaking on-load currents and on fast protection against overload and short circuit. The fused switch-disconnectors we supply comply with TS EN 60947-3 / IEC 60947-3 and have passed all type tests in accredited laboratories.

Why Powals?
Operational Continuity
On a fault only the faulty part is isolated; the rest of the plant keeps running.
Space-Saving in Panels
Integrated-CT vertical and compact horizontal types free up mounting space.
Fast Protection
The NH fuse reacts to short circuits far faster than thermal-magnetic breakers.
Reference Standards
Certificates and test reports belong to the supplied products and their manufacturers; shared with the quotation file.
Frequently Asked Questions
What is a fused switch-disconnector used for?+
A fused switch-disconnector provides both load switching and fuse-based short-circuit protection in LV circuits, enabling safe isolation.
