Product Description
Product Description
MOLDED CASE CIRCUIT BREAKER(MTEZC)
100,160,250,400,630
The MTEZC series Molded Case Circuit Breaker (MCCB) is a protective device designed specifically for low-voltage distribution systems, suitable for industrial, commercial, and infrastructure fields. The following is the core description of this series of products:
Economic solution: The EZC series focuses on high cost-effectiveness, meeting the needs of small and medium-sized power distribution, while balancing reliability and cost-effectiveness.
Application scenarios: Suitable for power distribution protection, motor protection (with corresponding release required), building electrical systems, etc.
Breaking capacity: Provides standard breaking capacity (such as 36kA, 50kA, etc.), covering most low-voltage distribution scenarios.
Current range: The frame current covers 63A to 630A and supports multiple rated current options.

Detailed Photos
Product quality: The shell frame is made of flame-retardant and high-temperature resistant materials, and the dynamic and static contacts are made of purple copper and silver plated materials.
The dynamic and static contacts are made of silver alloy material, which has high conductivity and resistance to arc erosion.
All products undergo a series of tests before being sold, such as instantaneous testing, delayed testing, etc., to ensure that the appearance and functionality of the product are intact before being sold
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.
Packaging & Shipping
-Inner packagingShockproof material
Material: foam, bubble film, etc
Placement: Place evenly around the circuit breaker, at the top and bottom
-External packaging
carton
Material: High strength corrugated cardboard box
Carton sealing
Method: Seal with tape or strapping
