S&C Alduti-Rupter Switches: Safety and Efficiency in Circuit Interruption
S&C's Alduti-Rupter Switches are designed to provide safe, arc-free interruption in overhead distribution lines and outdoor substations. Their advanced technology enables reliable load-breaking, ensuring optimal performance in network protection and management.
Maximum Reliability, Minimal Maintenance
✅ Safe, arc-free interruption – Complete protection for medium-voltage networks.
✅ Load breaking up to 630A – Capable of handling active loads with maximum efficiency.
✅ Virtually maintenance-free – Engineered for long-lasting performance without constant intervention.
✅ High-reliability contacts – Ensure safe and precise operation in every maneuver.
✅ Total versatility – Available in three-pole, single-pole, vertical, or inverted horizontal mounting configurations.
Outdoor distribution substations
The economics of power distribution has led to the overloading of substation transformers, increasing the number of feeders and the load of existing feeders. The S&C Alduti-Rupter switch is an ideal disconnector for these demanding tasks. It can share load, and break lines or cables or even the entire load. Its no-external-arc interruption operation is essential for substations where close phase spacings rule out the use of arc-producing disconnects.
No-external-arc interruption
Each S&C Alduti-Rupter switch has its own built-in interrupter, so no add-ons are required. Operation is simple and straightforward. Interrupter contacts separate at high speed, guided by a mechanism inside the interrupter driven by the movement of the blade.
