Description

Installation and Testing:

Model meaning

MT-EZC- refers to the type. 100A-1600A refers to the maximum peak current range of the molded case circuit breaker. Molded case circuit breaker is the keyword (MCCB is the abbreviation), and AC stands for AC, which can be used as a modifier.

The MTEZC series molded case circuit breakers (MCCBs) are superior protection devices designed specifically for low-voltage power distribution systems, ideal for industrial, commercial, and infrastructure applications. The following is a comprehensive overview of this product series: Economical Solution: The EZC series is carefully designed to provide excellent cost-effectiveness, meeting the requirements of small to medium-sized power distribution projects, achieving the best balance between reliability and economy. Application Scenarios: Perfectly designed for power distribution protection, motor protection (with necessary trip units), building electrical frameworks, etc. Breaking Capacity: Offers standard breaking capacities (e.g., 36kA, 50kA, etc.), effectively meeting most low-voltage power distribution needs. Current Range: Framework current spans from 63A to 630A, supporting a variety of rated current selections.

Environmental conditions for use

3. Normal Operating and Installation Conditions

3.1 Ambient Air Temperature

The upper limit shall not exceed +40°C, the lower limit shall not fall below -5°C, and the 24-hour average value shall not exceed +35°C. Note: Operating conditions with a lower limit of -10°C or -25°C must be confirmed by the user.

Operating conditions exceeding the upper limit of +40°C or falling below -10°C or -25°C must be negotiated with the user. 3.2 The installation location must not exceed 2000m above sea level.

3.3 Atmospheric Conditions

The relative humidity must not exceed 50% at an ambient air temperature of +40°C. Higher relative humidity is permitted at lower temperatures. The maximum average relative humidity in wet months is 90%, and the average minimum temperature for that month is +25°C. Condensation on the product surface due to temperature fluctuations must be considered. If the temperature exceeds these limits, the user must consult with the user. 3.4 Protection Grade: IP30

3.5 Usage Category: Class B or Class A

3.6 Installation Category

Circuit breakers and undervoltage releases with a rated operating voltage of 660V (690V) or less, and the primary winding of the power transformer, are intended for installation category N; auxiliary circuits and control circuits are intended for installation category III.

3.7 Installation Conditions

Circuit breakers must be installed in accordance with the requirements of this manual. The vertical tilt of the circuit breaker must not exceed 5° (mining circuit breakers must not exceed 15°).
