Description
For serious power distribution and the protection of high-capacity industrial systems, you need a circuit breaker with formidable strength and intelligence. The 400AMP 3-Pole YEM3Z Moulded Case Circuit Breaker (MCCB) is engineered to meet this challenge. This powerhouse of the YEM3Z family is designed to protect three-phase systems carrying substantial electrical loads, making it an indispensable component for main switchboards, heavy industrial machinery, and large-scale power generator outputs.
At 400 amps, the energy flowing through your circuits is immense, and so are the risks. A fault in such a system can lead to devastating consequences, including equipment destruction, prolonged downtime, and severe safety hazards. The 400A YEM3Z MCCB serves as a critical line of defense, offering state-of-the-art protection against both overloads and short circuits. It acts as an automatic, vigilant sentry, ready to disconnect the power in a fraction of a second at the first sign of trouble, thereby preserving your assets and ensuring a safe working environment.
Key Features & Benefits:
- Extreme High-Current Protection: With its 400A rating, this MCCB is built to manage and protect the main power feeds for entire buildings, large motor control centers (MCCs), and the primary outputs of diesel generators. It provides the robust capacity needed for the most demanding electrical loads.
- Adjustable Thermal-Magnetic Trip Unit: This model often features adjustable trip settings, allowing electricians to fine-tune the protection parameters to match the specific requirements of the circuit. This customization ensures optimal protection, minimizing the risk of nuisance tripping while maximizing safety.
- Exceptional Breaking Capacity (kA Rating): A high continuous current rating needs to be backed by an equally high breaking capacity. This MCCB is designed to safely interrupt massive fault currents, preventing the explosive effects of a short circuit and ensuring the device itself remains functional and ready to protect again.
- Superior Durability and Reliability: Constructed with a high-strength, thermoset plastic moulded case, the YEM3Z is resistant to heat, impact, and electrical arcing. This industrial-grade build guarantees a long service life and reliable performance, even in the harshest operating conditions.
- Designed for Professional Use: The breaker includes features that simplify its integration and management, such as clear on/off/trip indicators, a front-panel test button for functional checks, and compatibility with various accessories like shunt trips and auxiliary contacts for remote monitoring and control.
- Compliance with Global Standards (IEC 60947-2): Manufactured and tested in accordance with stringent international standards, the YEM3Z series provides a globally recognized assurance of quality, safety, and performance. This certification means you are investing in a product trusted by professionals worldwide.
The 400AMP 3-Pole YEM3Z MCCB is more than a component; it’s a fundamental part of your facility’s safety and operational strategy. It delivers the heavy-duty performance required to protect significant capital investments and maintain productivity. When you need to safeguard high-current three-phase circuits from the unpredictable nature of electrical faults, trust the proven strength and reliability of the YEM3Z 400A MCCB. Secure your power, secure your business.
