MOLDED CASE CIRCUIT BREAKER(MTEZC)
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.

-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.
Shockproof 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
Requirement: Ensure a secure seal to prevent cracking of the box
Identification and labeling
Content:Product model, quantity, weight, manufacturer, transportation label (such as fragile, upward, moisture-proof, etc.)
Location: Clearly printed on the outside of the cardboard box.
Transport
Domestic transportation
If there is a designated freight forwarder in china, we willtransport the products to the designated location through road transportation or domestic express delivery after production is completed
International transport
When the quantity of goods is small and time is tight, and it needs to be transported to a designated location abroad, the three majorinternational express delivery companies are selected for transportation
DHL,FEDEX,UPS
Sea freight/air freight
When there is a large quantity of goods and time is not urgent, we choose sea freight. We will choose a suitable freight company, who wil arrange for trucks to pick up the goods and transport them to the designated por for warehousing. Finaly, they will transpored by sea to the customer's desianated port, and the customer needs to pick up the goods with a bill of lading.
