NBSL1-100 Residual Current Circuit Breaker Type A, Rccb Circuit Breaker,Rcd A Type
1. APPLICATION
NBSL1-100 series residual current circuit breakers Is suitable for
the line of AC 50/60Hz, voltage 240V(2pole)/415V(4pole), rated
current up to 63A. When there is human electricity shock or if the
leakage current of the line exceeds the prescribed value, it will
cut off the power rapidly to protect human safety and prevent the
accident due to the current leakage. It can be used as infrequent
changeover of the line in normal situation. It is applicable to
industrial site, commercial site, tall building and civil house.
It complies with standard of IEC/EN61008.1 and GB16916.1.
Each phase of conductor at the circuit breaker passes through the
zero-sequence current transformer, and the secondary side of coil
connects with the electromagnetic tripper. Under normal condition,
the vector sum of each phase of current passing through
zero-sequence current transformer is zero. The flux of the
zero-sequence current transformer is zero. And the secondary output
voltage is zero and the circuit breaker doesn't zreo, and the
zero-sequence current transformer would produce the magnetic flux,
and the secondary side of coil would output the voltage. Once the
leak current increases to drive the output voltage at the secondary
side to grow to certain level, the electromagnetic release would
activate to drive the operation mechanism to act to break the
contact that connects the power, finally to realize the leak
protection.

Protection from Earth Leakage:
In order to achieve protection from earth leakage, 2 kinds of protection devices are used, based on 2 different concepts:
- Voltage sensing ELCBs
- Current sensing RCCBs
Voltage Sensing based Earth Leakage Circuit Breaker:
ELCB or Earth Leakage Circuit Breaker works on the principle of Voltage Sensing. ELCB is connected to the system such that one terminal is connected to the equipment for which the protection is required & the other terminal is connected to the earth. The voltage is measured between these 2 terminals which are observed as ‘0’ in an ideal case. However, in case of earth leakage, a voltage difference is created between these 2 terminals energizing the coil in the circuit breaker which in response trips the ELCB in case of earth leakage.
FAQ:
Q1: What's your product Range?
A.
- Shell Unti-fire. nylon pa66 or not unti-fire.
- Parts, Copper or iron
- Point Sliver point or Copper point
Q2: Are you a manufacturer?
A. Yes, we are only produce the circuit breaker over 20 years from
1999.
Q3: Do you have stock products to sell?
A. No,we work on OEM orders, The means, material, quantity,packing
solution,etc will depend on your requests.obviously, your logo can
be printed on the products.
Q4. what's the payment term?
A. We accept TT,30% deposit and 70% balance agaisnt copy of BL
Q5. how's the delivery time ?
A. usually it will take about 30 days for 30000pcs
Q6. tell me the standard of package?
A. Normally are cartons, color box or white box
Q7. what kind of material of circuit breaker?
A. we have two types, one copper coil with silver point and the
other is brass coil with copper point. It depends on your
requirement. In fact, those two have no difference if normal work
well. Only except the electrical life. Copper and silver is better
and also higer price.
Q8. We want to know month capacity.
A. 400,000pcs/month

A. Our products are popular in Western Europe, Middle-East, Afirca,
South Asia ,South Ameirca countries and area. Some of them are our
regular customers and some of them are developing. We hope you can
join us and make mutural benifit from our cooperation.
Q10. what kind of certificate you have ?
A. CE, CB,CCC,ISO9000.
Q11. Do you inspect the finished products
A. Yes.Each step of products will be inpected by QC department
before shipping.
Q12. How are you ship the finished products?
- By Sea
- By plane
- By counties,TNT, DHL,FEDEX,UPS.etc.
