Mini-Rupter^® Switches

Construction

1. Quick-make quick-break mechanism — factory installed; requires no adjustment. Its positive action contributes to Mini-Rupter’s ability to achieve fast circuit interruption and two-time duty-cycle fault-closing ratings.
2. Side barrier
3. Unified Cypoxy® insulated shaft positions blades in “fixtured” alignment. No clamp-on crank-and-connecting-link assemblies to portend alignment or simultaneity problems.
4. Multifinger, convex, silver-plated-copper jaw and hinge contacts, independently sprung and backed up with flat stainless-steel springs, providing equalized four-point pressure on the blades’ silver-clad contact surfaces.
5. Terminal pads
6. Multipurpose, one-piece, formed hard-drawn copper blades, with silver-plated-copper contact surfaces on both sides, are utilized for circuit closing, continuous current carrying, and circuit interrupting.
7. S&C’s unique arc compressor provides controlled circuit interruption without external arc or flame. No need for separate auxiliary blades.
