CHINT Button NP2-BD53

Detailed Introduction to CHINT Button NP2-BD53  

CHINT NP2-BD53 buttons are widely used in the industrial control field, providing reliable support for the control of relevant electrical circuits. The following is an introduction to it from multiple aspects:  

 Scope of Application  CHNT NL1E - 63A circuit breaker 

The NP2 series buttons are suitable for circuit environments with an alternating current (AC) frequency of 50Hz or 60Hz. The rated working voltage can reach up to 415V, and for direct current (DC) working voltage, the applicable upper limit is 250V. They are often used in industrial control circuits as control components for electromagnetic starters, contactors, relays, and other electrical circuits. For button types with indicator lights, they are also suitable for occasions requiring light signal indication, complying with the GB/T 14048.5 standard.  

 Meaning of Model  Chint NXBLE-40C6 residual current circuit breaker (RCCB)

- **NP2**: The model identifier for this series of buttons by CHINT.  

- **B**: Represents a metal head in the structural classification.  

- **D**: Indicates that the type code is a knob.  Chint NXR series thermal overload relays price

- **53**: The auxiliary specification code, where "5" may be related to specific attributes such as color or function (in the NP2 series, different numbers correspond to different color settings, etc.), and "3" indicates a configuration of two normally open contacts.  

 Performance Parameters  CHINT circuit breaker price

- **Rated Insulation Voltage (Ui)**: Reaches 600V, meaning the button can maintain good insulation performance in high-voltage environments, preventing circuit short circuits, leakage, and other issues to ensure safe use.  

- **Conventional Free Air Heating Current (Ith)**: 10A, reflecting the current value that the button can continuously pass through in a free air environment without performance degradation due to excessive heating.  

- **Mechanical Life**: The mechanical life of knob-type products is 300,000 cycles, indicating that the NP2-BD53 can still maintain stable mechanical performance under frequent operations, reducing failures caused by mechanical wear.  

- **Rated Impulse Withstand Voltage (Uimp)**: As high as 6kV, demonstrating the button’s strong capability to withstand instantaneous high-voltage surges and effectively protect itself and the controlled circuit equipment during abnormal situations such as voltage mutations.  

 Structural Design and Functional Features  

- **Modular Structural Design**: Facilitates flexible and free combination of buttons by users according to actual needs to adapt to different electrical control scenarios. For example, in complex control systems, button modules with different functions can be combined as required to build a complete control system.  

- **Contact Wiping Self-Cleaning Design**: The product’s contact wiping self-cleaning function can remove foreign matter and oxide layers from the contact surface during button operation, keeping the contact surface clean and ensuring reliable contact. This design greatly enhances the product’s adaptability to complex industrial environments and reduces poor contact issues caused by contact contamination.  

- **Silver Plating on Contact Surface**: By plating the contact surface with silver, the contact resistance is effectively reduced, the electrical conductivity is enhanced, and the contact reliability is further improved. This enables the NP2-BD53 to work stably under low-voltage and weak-current conditions, expanding its application range.  

 Appearance and Installation  

- **Appearance and Color**: The NP2-BD53 is black, a color design that meets the general requirements of industrial environments, being stable and dirt-resistant. The overall shape is a three-position reset knob, with simple and intuitive operation.  

- **Installation Details**: The button is panel-mounted and suitable for installation panels within a certain thickness range. For metal-head buttons, they are suitable for installation panels with a thickness of 1mm to 6mm; if they are plastic-head buttons (other models in the NP2 series may be involved), they are suitable for installation panels with a thickness of 1mm to 4mm. Taking a common Φ22 panel-mounted button as an example, its mounting hole diameter is Φ22.3 +0.4 0mm.

 Application Scenarios  

- **Industrial Automation Production Lines**: Used in various automated production equipment to control operations such as motor forward/reverse rotation and start/stop. For example, in automotive manufacturing production lines, the NP2-BD53 button can control the operating status of transportation equipment and processing equipment.  

- **Mechanical Equipment Control**: As key control components in the electrical control systems of machinery and equipment such as machine tools and cranes, they realize control of different equipment movements. Operators can easily achieve precise control of the equipment by rotating the knob.  

- **Power Distribution Systems**: Used in power distribution cabinets and panels to control circuit on/off, and can be used with indicator lights to facilitate operators in real-time understanding of circuit status.
