STM1-63 Device MCB Circuit Breaker White Plastic Texture High Working Reliability

STM1-63 Miniature Circuit Breaker​


STM1-63 series high breaking capacity mini circuit breaker is used in AC50/60Hz, rated voltage of 230V

3, 4 poles 400V, rated current to 63A for overload and short-circuit protection as well as for unfrequented switching under normal case.It is used extensively for industry, commercial and household.This product conform to IEC60898 standard.



General
1. Application:For protecting cables and equipments against overload and short circuit.
2. General rules for choosing MCB.

  1. 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.

  1. 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.)

FAQ
Q: If I'm interested in your DC MCB when I can receive your quotation and detail information after send the enquiry?
All your enquiry will be replied in 24hours.

Q: Your DC MCB seems perfect but what's the difference between you and other suppliers? Because I find some cheaper price from others!
Our DC MCB is special for Solar system all the parts in the MCB are high quality customized. Not all the MCB are DC MCB!

Q: Do you have a catalogue? Can you send me the catalogue to have a check of all your products?
Yes, We have product catalogue. Please contact us on line or send an Email to sending the catalogue.

Q: I need your price list of all your products, do you have a price list?
We do not have a price list of all of our products. Because we have so many items, and it is impossible to mark all of their price on a list. And the price are always changing because of the producing cost. If you want to check any price of our products, please feel free to contact us. We will send offer to you soon!
