    - **Thermomagnetic Protection Function**: It integrates thermal overload protection and electromagnetic short-circuit protection functions. When the motor is overloaded, the thermal element will generate heat to make the bimetallic strip bend and push the tripping mechanism to act; when a short-circuit fault occurs, the electromagnetic trip will act quickly to cut off the circuit and protect the safety of the motor and the line.

    - **Undervoltage Tripping Function**: It is equipped with an undervoltage tripping module. When the power supply voltage is lower than a certain value, the circuit breaker will automatically disconnect to prevent the motor from running under undervoltage conditions and avoid the motor from being burned out due to excessive current.

    - **Shunt Tripping Function**: The shunt tripping module can be used to remotely control the disconnection of the circuit breaker, which is convenient for remote operation or cooperation with other automated control systems.CHINT-Circuit Breakers Price

    - **Isolation Function**: In line with IEC 60947-1§7-1-6 standard, it can provide reliable isolation when the circuit breaker is disconnected to ensure the safety of maintenance personnel.

    - **Phase Loss Protection Function**: It is sensitive to the phase loss fault in the three-phase circuit and can act in a timely manner when a phase loss occurs to protect the motor.

    - **Long Mechanical and Electrical Life**: The mechanical life can reach 100,000 times, and the electrical life under the AC-3 use category is 100,000 times at 440V, which can operate stably for a long time.Chint NXR series thermal overload relays price

- Supports Modbus RTU communication (through an expansion module).

- The environmental temperature compensation range is expanded to -25℃ to +60℃.

It is recommended that users confirm the model suffix when purchasing to obtain the latest functions. If technical documents are required, you can visit the [Schneider Electric official website] to download the CAD drawings, installation manuals and certification certificates of GV2PM32C. 

The installation dimensions and related parameters of Schneider GV2PM32C are as follows:

 I. Core Installation Dimensions

1. **Overall Dimensions**

   - **Height**: 89 mm (including the knob operation part)

   - **Width**: 44.5 mm (in line with the standard modular design, occupying a 45mm installation space)

   - **Depth**: 91 mm (including the protruding part of the terminal block)

   - **Weight**: 0.26 kg

   This dimensional design enables it to be compactly installed in standard power distribution cabinets, especially suitable for industrial control scenarios that require high-density layout.

2. **Rail Installation Parameters**

   - **Rail Type**: 35mm DIN standard rail (EN 50022)

   - **Installation Direction**: Supports vertical or horizontal installation. Vertical installation is recommended to ensure the heat dissipation effect.

   - **Adjacent Spacing**: When installed side by side with other modules, a gap of at least 5mm should be reserved to ensure ventilation.

   The rail clamping structure adopts a metal spring piece design, and it can withstand a mechanical impact of 0.5J after installation (in line with IEC 60068-2-27 standard).

 II. Wiring and Terminal Dimensions

1. **Wiring Capacity**

   - **Power Supply Terminal**: Supports solid wires of 1-6mm² or flexible wires of 1.5-6mm², with a tightening torque of 1.7N·m.

   - **Control Wire Terminal**: If auxiliary contacts (such as OF/SD modules) are added, an additional space of 2.5mm² for control wires needs to be reserved.

   The terminals adopt screw-type connections, with a cylindrical structure inside. The wiring operation can be simplified through the funnel-type wire inlet method.

2. **Mounting Hole Dimensions**

   - **Fixed Installation**: If screw fixation (not rail installation) is adopted, M4 screws should be used, and the spacing of the mounting holes is:

     - Horizontal direction: 70 mm

     - Vertical direction: 45 mm

   This hole position design is compatible with various installation methods and is suitable for non-standard cabinets or occasions that require redundant fixation.

III. Space Planning Suggestions

1. **Cabinet Space Reservation**

   - **Single Unit Installation**: It is recommended to reserve at least 100mm (width) × 100mm (height) × 100mm (depth) of space in the power distribution cabinet for easy wiring and maintenance.

   - **Multiple Units in Parallel**: For each additional circuit breaker, the width needs to be increased by 45mm, and the depth remains unchanged.

   Actual cases show that in the power distribution cabinet of a production line in an automobile factory, 30 GV2PM32C circuit breakers are installed in parallel, and the total width is only 1.35 meters, significantly saving space.

2. **Heat Dissipation Requirements**

   - **Ambient Temperature**: -20℃ to +60℃ (for the main body), -20℃ to +40℃ (inside the cabinet)

   - **Ventilation Design**: It is recommended to set louver windows at the top and bottom of the cabinet to ensure that the ventilation volume for every 10 circuit breakers is not less than 50CFM.

   If the installation environment temperature exceeds 40℃, the rated current needs to be adjusted at a ratio of reducing the capacity by 5% for every 10℃ increase.

 IV. Dimension Comparison and Model Selection Reference

From a comprehensive perspective of dimensions and performance, GV2PM32C achieves a balance between a compact design and breaking capacity, especially suitable for OEM equipment with limited space or renovation projects.

V. Installation Precautions

1. **Wiring Specifications**

   - The phase wires should be connected in the order of L1/L2/L3, and the neutral wire (N) does not pass through the circuit breaker.

   - The yellow-green double-color grounding wire should be connected to the dedicated grounding bar of the cabinet, and the wire diameter should not be less than 2.5mm².

   - It is recommended to use shielded twisted-pair wires for the control wires, and keep a distance of at least 150mm from the main circuit to avoid interference.

2. **Maintenance Space**

   - At least 50mm of rotation space should be reserved for the operation knob.

   - It is recommended to disconnect the upper-level power supply during maintenance and use insulated tools to remove the terminal screws.

   - The elasticity of the bimetallic strip and the sensitivity of the electromagnetic tripping mechanism should be checked annually, and Schneider Tesys T tools can be used for verification.

3. **Environmental Compatibility**

   - In a dusty environment, an IP55 protective housing (such as a dedicated explosion-proof box of the GV2 series) should be equipped.

   - In a humid environment, it is recommended to select a model with an anti-condensation coating (with the suffix -P).

   - When the altitude exceeds 2000 meters, the capacity needs to be reduced for use (reduce the capacity by 5% for every 1000 meters increase).
