Number of poles According to the
1. Single-pole (1P, 1P). It is locat in the circuit and protects one wire and one phase. Such machines are chosen for lighting and separately connect equipment.
According to theSingle-pole circuit breaker Schneider Electric (picture with link to catalog))
2. Two-pole (2P, 2P). Us to completely disconnect the electrical wiring network from voltage. It is us as an input when, during a short circuit or lebanon email list 484456 contact leads network failure,
all electrical wiring is de-energiz at the same time. This allows for timely repairs and circuit upgrades to be carri out absolutely safely. Two-pole circuit breakers are us in cases where a separate switch is requir for a single-phase electrical appliance, such as a water heater, boiler, or machine tool.
Connect the circuit breaker
To the requir device using 4 wires: two wires – power (one is connect to the network, the second supplies power via a jumper).

3. Three-pole circuit breakers (3P, 3P) are mainly us to protect a three-phase 3- or 4-wire network. Connection type: star (middle wire without protection,
and phase wires to the poles), or triangle (without central wire).

4. Four-pole circuit breakers (4P, 4P) are us to protect 3-, 4-phase electrical networks, connect according to the principle of “star with a neutral point brought out”. It is us as an input switch for a three-phase four-wire network. It is possible to philippines numbers connect eight wires to the body of the circuit breaker,
three of which are phase wires of the electrical network (+ one neutral) and four are represent by outgoing wires (3 phase + 1 neutral).

They are divid into the following types: According to the
