Description
When you reach the upper echelons of power distribution, you require a circuit breaker of unparalleled strength and sophistication. The 800AMP 3-Pole YEM3Z Moulded Case Circuit Breaker (MCCB) is that device. A true juggernaut of electrical protection, this MCCB is engineered to safeguard the main power arteries of large industrial plants, major commercial buildings, and utility-grade generator sets. Its massive 800A capacity makes it the cornerstone of any serious high-current, three-phase electrical system.
Managing 800 amps of current is a task that leaves zero margin for error. A fault at this level is not a minor inconvenience; it’s a potentially catastrophic event that can lead to explosive equipment damage, extensive fires, and life-threatening safety risks. The YEM3Z 800A MCCB is designed to stand as a formidable barrier against such events. It provides constant, vigilant protection against both sustained overloads and instantaneous short circuits, automatically cutting power in the blink of an eye to contain faults before they can escalate.
Key Features & Benefits:
- Immense 800A Power Rating: This MCCB is purpose-built for the most demanding applications, serving as the main incoming breaker for entire facilities or protecting the largest individual loads, such as industrial furnaces, chillers, or heavy-duty motors.
- Fully Adjustable Electronic Trip Unit: At this power level, precision is key. This MCCB is typically equipped with an advanced electronic trip unit offering a wide range of adjustable settings: long-time (overload), short-time, and instantaneous (short circuit) protection. This allows for meticulous system coordination and selectivity, ensuring maximum operational continuity.
- Exceptional Fault Interruption (High kA Rating): The 800A YEM3Z boasts an extremely high breaking capacity, enabling it to safely interrupt the massive energy released during a major short circuit. This capability is crucial for protecting the entire electrical infrastructure from the violent forces of high-current faults.
- Built for Maximum Reliability: Encased in a high-strength, arc-resistant thermoset material, this MCCB is designed for supreme durability. Its robust mechanical structure and high-quality internal components guarantee a long service life with consistent, reliable performance.
- Advanced Features for Modern Power Systems: Beyond basic protection, this breaker often includes communication capabilities (e.g., Modbus) for integration with modern Power Management Systems. This allows for remote monitoring of current, status, and trip history, facilitating proactive maintenance and energy management.
- Designed for Ease of Use and Safety: Despite its size, the 800A YEM3Z is designed for straightforward installation and maintenance. It features clear status indicators, a test function to verify the trip mechanism, and is compatible with a range of accessories like motor operators for remote control.
- Certified to the Highest International Standards (IEC 60947-2): Rigorous testing and certification to global standards provide ultimate confidence in its safety and performance. This is a product engineered to meet the demands of professionals who require the best.
The 800AMP 3-Pole YEM3Z MCCB is the ultimate solution for protecting your most significant electrical assets. It combines raw power-handling capability with intelligent, highly customizable protection. When your operations depend on a reliable and safe high-current power supply, this breaker delivers the performance and peace of mind you need.
