St32 1P Series RCCB Residual Current Circuit Breaker
Product Over View:
1. Provide protection against earth fault/leakage current and
function of isolation
2. High short-circuit current withstand capacity
3. Applicable to terminal and pin/fork type busbar connection
4. Equipped with finger protected connection terminals
5. Automatically disconnect the circuit when earth fault/leakage
current occurs and exceeds the rated sensitivity
6. Independent of power supply and line voltage, and free from
external interference, voltage fluctuation.
General
1. Application:For protecting cables and equipments against
overload and short circuit.
2. General rules for choosing MCB.
Technical data of the network at the point considered
The earthing systems,short-circuit current at the circuit breaker
installation point,which must always be less than the breaking
capacity of this device,network normal voltage.
There are 3 curvve characteristics for magnetic operation:
B curve (3-5In) protection and control of the circuits against
length cables in TN and IT systems.
C curve (5-10In) protection and control of the circuits against
overloads and short-circuits; protection for resistive and
inductive loads with low inrush current.
D curve (10-14In) protection and control of the circuits against
overloads and short-circuits; protection for circuits which supply
loads with high inrush current at the circuit closing (LV/LV
transformers,breakdown lamps.)
