MCB FTCQP 1 Pole 20A TPN MCB 50Hz Electrical Circuit Breaker

Brevis descriptio:

1. Applicatio: Pro tuendis funes et instrumentis contra oneris ac brevibus circuitionibus.

2. Regulae generales pro eligendo MCB.

a. Technica notitia reticuli in puncto considerato: Systemata terrestris, brevis circuitus currentis in puncto institutionis ruptor ambitus, qui semper minor esse debet quam capacitas huius fabricae fracturae, voltage retis normali.

b. Sunt notae 3 curvae operationis magneticae: curva B(3-5 In) tutelae ac imperium circuitus contra longitudinis rationum rudentes in TN et IT.

c. curvae (5-10 In) circuitus tutelae ac potestates contra onera et breves circuitus; munimenta resistentia et inductiva onera incursus humiliores.

Dcurve (10-20 In) circuitus tutelae ac moderatio contra onera et breves circuitus; munimentum gyrorum qui onera magna accurrentium currentium suppeditant in circumitu claudendi (LV/LV transformatores, lampades naufragii).
