Description：

The MTNSX series molded case circuit breakers (MCCBs) are high-performance electrical protection devices widely used in industrial, commercial, and infrastructure sectors. Their core features include:

1. High breaking capacity:

High breaking capacity ensures reliable protection of electrical systems under short-circuit or overload conditions.

2. Modular design:

Supports various functional modules (e.g., residual current protection, communication modules) to meet diverse needs.

3. Precise protection:

Equipped with thermal-magnetic or electronic trip units, providing precise overload, short-circuit, and ground fault protection.

4. Compact design:

Saves installation space and is suitable for high-density distribution cabinets.

5. Intelligent functions:

Supports communication interfaces (e.g., Micrologic) for remote monitoring and energy management.

6. High durability:

Utilizes high-quality materials and advanced technology to ensure long service life and stable performance.

Product testing

-Factory testing
● Mechanical operation testing
Content: Operate the circuit breaker multiple times to check whether the opening and closing are flexible and reliable.
● Insulation resistance test
Content. Use an insulation resistance tester to measure the insulation resistance between each pole of the circuit breaker and between the pole and the casing.
● Voltage withstand test
Content: Apply high voltage (usually twice the rated voltage+1000V) for 1 minute and check for breakdown.
● Temperature rise test
Content. Run at rated current and measure the temperature rise of wiring terminals and contacts.

-On site testing
● Power-on test
Content: Check if the circuit breaker can open and close normally after power on.
● Protection function test
Overload protection: Simulate overload and check if the circuit breaker trips within the specified time.
Short circuit protection: Simulate a short circuit and check if the circuit breaker trips instantly.

Installation method:

● Fied installation

Distribution box: installed inside the distribution box to ensure firmness.

● Vertical installation

Direction: Usually installed vertically, with the operating handle facing upwards

Avoid: inverted installation, unless permitted by the product.

● Connection

Power cord: Connect to the input terminal of the circuit breaker (marked as "L1", "L2", "L3")

Load line: Connect to the output terminal (marked as "T1","T2","T3")

Grounding wire: lf there is a grounding terminal, it must be firmly connected.

● Distance requirements

Spacing: Maintain sufficient distance from other devices for easy heat dissipation and maintenance.

Reference: Please refer to the product manual for specific spacing.

● Safety precautions

Power off operation: The power must be cut off during installation to prevent electric shock.

Protective equipment: Wear insulated gloves and goggles

Standard compliance: Strictly follow the electrical installation specifications for operation
