| DNB1LD-63 Residual current action breaker |
 |
Application Range: |
DNB1LD-63 residual current action breaker (called as the creepage breaker) is applicable to the line with AC 50/60Hz, two pole 230V, four-pole rated voltage400V, and the current from rated current to 63A,when the physical body suffers from an electric shock or the creepage of the power grid exceeds the regulated value, the residual current action breaker will quickly cut off the power within a very short period and protect from the security of the physical body and power device, it can also be used for non-frequent transformation of the line and non-frequent start of the electromotor. It does not include the overload and short-circuit protection function.
This product is applicable to various sites such as industry, commerce,high-rise and civil house.
This product meets the lEC61008 and GB16916.1-1997 standard. |

Main specs and technical parameters: |
1. Main specification
1.1 Divided by the rated current In: 25A, 40A, 63A.
1.2 Divided by the rated residual action current: 0.03A, 0.1A, 0.3A.
1.3 Divided by pole count:
a. Two-pole residual current action breaker:
b. Four-pole residual current action breaker:
2. Technical parameters
2.1 Rated switch on and breaking capability: In=25A,40A£¬500A£»ln=63A£¬630A£»
2.2 Rated residual switch-on and breaking capability: I¡÷m£ºIn=25A,40A£¬500A£»In=63A£¬630A£»
2.3 Rated limit short circuit current: 6000A£»
2.4 Rated limit residual short circuit current l¡÷c£º6000A£»
2.5 Rated residual non-action current: l¡÷no£º0.5 I¡÷n£»
2.6 Breaking time of residual current action
2.7 Mechanical electric life: the residual current action breaker should be able to bear the cycle times regulated in the table 2.
2.8 The residual current action breaker can bear the peak current 200A impact current and peak voltage 2.5 2Un surge voltage and will not result in erroneous action.
2.9 Insulation impact-resistance voltage performance
a. Each pole is connected together and the bearable peak impact voltage between the pole and neutral pole is 6000V.
b. Each pole and neutral pole is connected together and the bearable peak impact voltage between the pole and metal rack is 8000V
Structure feature:
1. No assisted power is used, so it overtimes the disadvantages of the electronic products such as bad anti-interference, great influence from the power grid voltage fluctuation and non protection caused by the neutral line cut-off, so it broadens the residual current protection scope.
2. High rated limit short circuit current is up to 6kA.
3. Connection terminal with combined finger protection is highly secure.
4. The operation reliability does not change under the environmental pollution condition.
5. The shell body and part are made of the foreign imported high combustion-resistance, high-temperature-resisting and impact-resisting plastic.
6. Modular dimension and convenient installation
7. Dynamic test set makes the button flexible and reliable. |
