Product Features

- 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.

This is a demonstration on how I connected two UPS’s together to double the output power capability and make a 3000 Watt sinewave inverter. There are some considerations in doing this which I do not cover in the video, and attempting this is a good way to destroy two UPS’s/Inverters so think things through and be careful!

I used Smart UPS 1500 RM2U units, but this general information applies to all APC Smart UPS models and I believe it can be made to work with any APC Smart UPS product of this vintage.

Although no special precautions are needed to do what is shown in the video, this setup is capable of producing a voltage level more dangerous than that of a typical 240V electrical outlet and is potentially lethal. Please only attempt this if you are familiar with basic electrical safety or have experience working with dangerous voltage levels.
