NBSe BF62 Series Residual Current Circuit Breaker, rcd switch
NBSL1-100 series residual current circuit breakers are applied to the lines with AC 50/60Hz,rated voltage of230V(1P+N) or 400V(3P+N),and rated current of 100A.In case of electric shock or electric leakage current exceeds the specified value, the residual current circuit breaker can switch off the fault circuit in a very short time, protecting the safety of person and electric equipment.
Can be used in the industrial, commercial, high-rise buildings, civil residences and other places.
· Phase (line) and Neutral both wires connected through RCD.
· It trips the circuit when there is earth fault current.
· The amount of current flows through the phase (line) should return through neutral .
· It detects by RCD. any mismatch between two currents flowing through phase and neutral detect by -RCD and trip the circuit within 30Miliseconed.
· If a house has an earth system connected to an earth rod and not the main incoming cable, then it must have all circuits protected by an RCD (because u mite not be able to get enough fault current to trip a MCB)
· RCDs are an extremely effective form of shock protection
The most widely used are 30 mA (milliamp) and 100 mA devices. A current flow of 30 mA (or 0.03 amps) is sufficiently small that it makes it very difficult to receive a dangerous shock. Even 100 mA is a relatively small figure when compared to the current that may flow in an earth fault without such protection (hundred of amps)
A 300/500 mA RCCB may be used where only fire protection is required. eg., on lighting circuits, where the risk of electric shock is small.
APPLICATION
A residual-current device (RCD), or residual-current circuit breaker (RCCB), is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock.
· Line voltage independent RCCB for fault or additional protection with additional digital features
· System Monitoring: Preventive information / warning before the RCD trips in case of leakage currents: Integrated auxiliary contact(s), Local Indication
· New level of accuracy - Reduced unwanted tripping
· Local status indication of residual current through 3 LEDs
· No monthly test required
· Comprehensive range of accessories
· Real contact position indicator
· Fault current tripping indicator
· Automatic re-setting possible
· Transparent designation plate

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.
