LZMN3-AE400 Industrial Molded Case Circuit Breaker

Advanced Electrical Protection

The LZMN3-AE400 is a robust molded case circuit breaker (MCCB) designed for the protection of electrical systems in industrial and commercial buildings. With a rated current of 400A, it is capable of protecting large-scale power distribution networks from short circuits and thermal overloads, ensuring the safety of both equipment and personnel.

Technical Specifications and Trip Units

This MCCB features an electronic trip unit that allows for precise adjustment of protection parameters. The "AE" designation indicates an adjustable electronic trip, allowing engineers to fine-tune the long-term and short-term delay settings to match the specific requirements of the connected load. This flexibility is crucial for preventing nuisance tripping during motor start-ups.

Safety and Performance Attributes

• High Breaking Capacity: Designed to safely interrupt high fault currents, preventing damage to downstream equipment.

• Compact Design: Despite its high current rating, the LZMN3-AE400 features a space-efficient footprint for installation in modern switchboards.

• Isolation Properties: Provides reliable electrical isolation for maintenance tasks, compliant with international safety standards.

Installation and Connectivity

The LZMN3-AE400 is designed for easy mounting and connection using standard busbars or cable lugs. It supports a wide range of accessories, including auxiliary contacts, shunt trips, and undervoltage releases, allowing it to be integrated into comprehensive building management or industrial control systems.
