Description
When your operations depend on high-current machinery and robust power distribution, you need a circuit breaker that can handle the load. The 250AMP 3-Pole YEM3Z Moulded Case Circuit Breaker (MCCB) is engineered precisely for these demanding environments. As a cornerstone of the esteemed YEM3Z series, this 250A MCCB delivers unwavering protection for three-phase systems, making it the premier choice for industrial plants, large commercial complexes, and substantial generator applications.
Power systems rated for 250 amps are significant investments, and protecting them is paramount. This YEM3Z MCCB acts as a vigilant guardian, continuously monitoring the circuit for signs of overloads and short circuits. An overload, where the current slightly exceeds the rated capacity for an extended period, can cause wires to overheat, insulation to melt, and create a serious fire risk. A short circuit, a sudden and massive surge of current, can cause explosive damage to equipment. This MCCB is designed to intelligently detect and instantly react to both threats, disconnecting the power in milliseconds to prevent damage and ensure safety.
Key Features & Benefits:
- High-Current Capacity: With a 250A rating, this MCCB is perfectly suited for main distribution boards, sub-main circuits, and protecting large motors, HVAC systems, and other heavy-duty equipment that define modern industry.
- Reliable Dual-Trip Mechanism: The advanced thermal-magnetic trip unit offers two layers of defence. The thermal protection provides an inverse time-delay response, tolerating harmless inrush currents from motors while tripping on sustained overloads. The magnetic protection offers instantaneous tripping on high-level fault currents, safeguarding against the most dangerous electrical events.
- Built for Extreme Conditions: The YEM3Z MCCB is encased in a robust, high-dielectric strength, and flame-retardant moulded housing. This rugged construction ensures reliable operation in challenging industrial settings with vibrations, temperature fluctuations, and dust.
- Superior Breaking Capacity: This breaker is not just rated for 250A of continuous current; it’s also designed with a high breaking capacity (kA rating) to safely interrupt massive fault currents without failure. This ensures the protection of your entire electrical system and the safety of your personnel.
- Simplified Installation and Operation: Designed with the installer in mind, the YEM3Z MCCB features easily accessible terminals and a compact form factor for its power class, facilitating a smooth fit into switchboards and panels. The clear on/off/trip indication and front-panel test button make it easy to operate and maintain.
- Internationally Certified Quality: Meeting the strict requirements of IEC 60947-2, this MCCB stands as a testament to quality manufacturing and engineering excellence. This certification ensures it performs reliably and safely, giving you confidence in your circuit protection strategy.
The 250AMP 3-Pole YEM3Z MCCB is the definitive solution for protecting high-power three-phase circuits. It provides the strength, intelligence, and reliability needed to manage significant electrical loads safely. Whether you’re safeguarding a manufacturing line, a commercial building’s power backbone, or a large-scale generator, this circuit breaker delivers the performance you can trust. Upgrade your system’s safety and reliability by investing in the proven power of the YEM3Z series.
