- A breaking capacity of 12kA up to 32A and 10kA between 40 to 63A.
- Current-limiting scheme: in the event of a short circuit, are able to limit the let-through current to 60%-70% of the rated current.
- The trip mechanism ensures perfect closure every time,thereby considerably improving the performance of these devices and extending their average lifetime.
-The arc extinguishing system: allows the short-circuit currents of very high value to be interrupted extremely rapidly, the remarkable opening speed of contacts opening and the structure of the arcing chamber contribute to extinguishing the arc in the shortest possible time, ensuring reliable protection of short-circuit.
- The internal contact position allows an exact information of the circuit-breaker status: “green”,open contacts;“red”,closed contacts,independently of the toggle position.
- Sealing/locking sealable with 1 mm wire, to prevent unwanted tripping.
- The supply lines of the protected circuit can be connected to either the upper or lower terminals of the circuit-breakers(reversibility of connections).
- The double terminal of these circuit-breakers enables simultaneous connection of cables and busbars.

Mark Donovan of http://www.HomeAdditionPlus.com shows how to wire a switch outlet combo circuit such that the outlet is controlled by the switch. Wiring a combo switch outlet circuit is easy to do if you understand a few key features of the combo switch outlet. Make sure, however, to always turn power off at the main circuit panel before doing any electrical wiring.
