MeTEK7 Series Moulded Case Circuit Breaker

Description

The MeTEK7 series molded case circuit breaker is a high-performance, multi-functional and easy-to-operate electrical protection device. It features dual core protection functions (power distribution protection and motor protection), with a breaking capacity ranging from 25kA to 70kA and a rated current range of 16A to 800A. Suitable for most industrial and civil application scenarios, it adapts to various installation environments and methods, serving as an ideal power distribution solution that balances reliability and flexibility.

Features

• Comprehensive Protection & Strong Adaptability: Supports power distribution protection and motor protection. With service short-circuit breaking current (Ics) equal to ultimate short-circuit breaking current (Icu), it delivers reliable short-circuit protection performance.
• Flexible Configuration & Rich Options: Offers multiple types of trip units (electronic with complex functions, thermal-magnetic, and electromagnetic) paired with a variety of accessories to meet functional requirements of different scenarios.
• Excellent Environmental Resistance: Operating temperature ranges from -35℃ to +70℃ (24-hour average not exceeding 35℃), and storage temperature from -40℃ to +75℃. Adapts to an altitude of ≤2000m (derating applicable for high altitudes) with Pollution Degree 3. Relative humidity shall not exceed 50% at 40℃ and can reach up to 90% at 20℃ (condensation prevention measures required).
• Standardized Installation & Wide Compatibility: Installation category for the main circuit is Category Ⅲ (power distribution and control level), and Category Ⅱ (load level) for auxiliary and control circuits. Supports vertical installation (inclination ≤±22.5°) or horizontal installation. Must be installed away from explosive hazards, corrosive gases, conductive dust, and exposure to rain and snow.
• Low Maintenance & High Stability: Designed to meet the frequent operation needs of industrial scenarios, it boasts stable mechanical and electrical performance, reducing long-term maintenance costs.
