Product Feature

- These circuit breakers are intended for the protection of circuits against overloads and short circuits in residential, commercial and industrial premises;

- It covers the rating range from 6 to 63A with a uniform breaking capacity of 6.5 kA throughout;

- 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 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;

-The sensitivity and reliability of the trip mechanism ensures perfect closure every time,thereby considerably improving the performance of these devices and extending their average lifetime;

- 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.

Finding out if you need to replace a breaker is easy if you follow these tips.

Step 1: Open the electrical box
Open the circuit breaker box and locate the switch that corresponds to the area you want to test.

Tip
Turn off or unplug the electric devices in the area to avoid a power surge.

Step 2: Test the switch
Determine whether the breaker is in the On or Off position. If it’s off, flip to the On position.

Tip
If the breaker trips after a few seconds, there may be a problem with the wiring.

Step 3: Connect the prongs
Touch one of the multimeter’s prongs to the terminal screw, and touch the other prong to the ground screw.

Step 4: Check the readout
Check the readout on the multimeter or look for an indicator light. If no voltage is indicated, then no power is reaching the breaker and it will need to be replaced.

Did You Know?
A volt is the measure of the unit of the force that sends electrons through a circuit.
