Chint SHT-X1 shunt release

# Chint SHT-X1

The Chint SHT-X1 is a **shunt release** specifically designed for the NXB series circuit breakers. It is mainly used for remote control of circuit breaking and is widely applied in residential, commercial, and industrial scenarios. Below is its core information and usage recommendations:

 I. Product Functions and Technical Parameters

1. Core Functions  

The SHT-X1 needs to be used in conjunction with circuit breakers of the NXB-63, NXB-40, and other series. It realizes **remote breaking operations** through an external power supply—for example, triggering power cutoff in a fire alarm system or achieving automated management via an intelligent control system. Its operating characteristic is that it can reliably trip within the range of 70% to 110% of the rated control power supply voltage, ensuring stable operation even when the voltage fluctuates.

2. Voltage Compatibility  

It supports multiple voltage specifications:  

- **AC 230V/400V** (suitable for residential and commercial electricity use)  

- **AC/DC 24V/48V** (suitable for low-voltage control systems or industrial equipment).  

The rated insulation voltage is 500V, which can adapt to electrical environments in different scenarios.

3. Mechanical Performance  

- Mechanical durability: ≥ 4000 operating cycles, ensuring high stability during long-term use.  

- It adopts a standard TH35-7.5 mounting rail. For wiring, 1.0mm² copper wires (with a wire stripping length of 9mm) must be used to ensure reliable connection.

 4. Auxiliary Functions  

When the release is in the open state, terminals C2 and 12 are connected (the safety signal light is on); when it is in the closed state, terminals C2 and 14 are connected (the warning signal light is on), facilitating real-time monitoring of the circuit status.

 II. Application Scenarios and User Value

 1. Residential and Civil Scenarios  

- **Remote Control**: For instance, remotely cutting off the power supply of non-essential loads via a mobile APP or intelligent panel, improving electricity usage safety and convenience.  

- **Fire Linkage**: It links with the fire alarm system to automatically cut off the power supply in emergency situations, preventing the spread of electrical fires.

2. Commercial and Industrial Scenarios  

- **Automated Management**: It cooperates with intelligent distribution boxes to realize functions such as scheduled power cutoff and energy consumption monitoring, suitable for places like stores and offices.  

- **Emergency Response**: In factories or data centers, it can quickly break down faulty circuits through the central control system, reducing downtime.

3. Cost-Effectiveness Advantage  

The price on e-commerce platforms is approximately 29-30 RMB. It supports modular assembly with circuit breakers, requiring no additional modification to the distribution box, thus lowering the installation cost.

 III. Installation and Usage Precautions

 1. Correct Wiring  

- Wire strictly in accordance with the instruction manual, and avoid reversing the live wire and neutral wire; otherwise, the release may be burned out.  

- It is recommended that the wiring be operated by professional electricians to ensure that the wiring screws are tightened and poor contact is prevented.

2. Environmental Adaptability  

- **Temperature Range**: -5°C to +40°C (average ≤ +35°C), suitable for most indoor environments.  

- **Protection Class**: The supporting circuit breaker has an IP20 rating (dust-proof but not waterproof). It is recommended to install it in a dry environment to avoid direct contact with moisture or dust.  

- **Pollution Degree**: Degree 2 (suitable for general industrial environments). However, in areas with high humidity or haze, it is recommended to regularly inspect and clean the distribution box.

3. Maintenance and Testing  

- Regularly check whether the connection between the release and the circuit breaker is loose, and ensure that the mechanical movement is flexible.  

- Avoid using the short-circuit testing method to verify the function, so as not to damage the equipment.

IV. After-Sales Service  

- The product comes with a quality guarantee. In case of performance issues, you can contact the distributor via WhatsApp: 0086-13811255435. Users are required to keep the purchase certificate and product qualification certificate for the convenience of quickly handling after-sales issues.

V. Summary  

The Chint SHT-X1 is a cost-effective shunt release. With its flexible voltage compatibility, reliable mechanical performance, and convenient installation method, it has become an ideal choice for remote control of circuits in residential, commercial, and industrial fields. When used in areas such as Shijiazhuang, it is recommended to take into account the local climate conditions (e.g., high humidity or haze), regularly inspect the equipment status, and take additional protective measures (such as installing a moisture-proof box) if necessary to ensure long-term stable operation. Before purchasing, you can contact local distributors to obtain the latest product information and installation guidance.
