Product Description

NBS01632010 63A 2 POLE 100mA ELCB RCCB

 

1. APPLICATION

 

BF60 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.

Principle behind RCCB

RCCB works on the principle of Kirchhoff’s law, which states that the incoming current must be equal to the outgoing current in a circuit. RCCB thus compares the difference in current values between live and neutral wires. Ideally, the current flowing to the circuit from the live wire should be the same as that flowing through the neutral wire. In case of a fault, the current from the neutral wire is reduced, the differential between the two known as Residual Current. On spotting a Residual Current, the RCCB is triggered to trip off the circuit.

A test circuit included with the Residual Current device ensures that the reliability of RCCB is tested. When the test button is pushed, the current starts to flow through the test circuit. As it creates an imbalance on the neutral coil of the device, the RCCB trips and supply is disconnected thereby checking RCCB’s reliability.

 

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.
