Z2UA12PD205U is a type of heavy-duty, quick-acting, one-to-three phase electromagnetic circuit breaker designed for industrial applications. It has been designed to provide reliable overcurrent, short and medium circuit protection. It is available with adjustable trip settings, allowing the user to customize the breaker to their particular application’s requirements.

The main application field of the Z2UA12PD205U is as circuit breaker in major power plants, since it is particularly suitable for this kind of application due to its construction materials, quality of construction, robustness and fastness of operations when an emergency situation occurs. It can be placed in AC and DC applications alike in three-phase or single-phase configurations, further giving the user a lot of flexibility when choosing the breaker. The Z2UA12PD205U is also very popular among industrial and commercial applications due to its low maintenance requirements.

The working principle of the Z2UA12PD205U is based on a solenoid coil connected to the circuit breaker. When an overcurrent condition is detected, the solenoid coil closes the temporary electrical contacts of the breaker, which in turn opens the electrical contacts permanently, hence breaking the circuit. The solenoid coil then de-energizes the circuit breaker. This mechanism ensures fast and quick operation while providing reliable short circuit protection.

The Z2UA12PD205U features a unique design which offers various benefits such as increased safety, protection from accidental tripping, and fast operation. A pre-closure relay is provided to ensure the solenoid coil is energized prior to full closing, thus preventing an accidental short circuit or arc flash. The solenoid coil is made from high-grade material to ensure reliable operations of the circuit breaker. The breaker also has a manual operating handle to open and close the circuit breaker in case of emergency.

In summary, the Z2UA12PD205U is an excellent choice for industrial and power applications due to its fast and reliable operation, adjustable trip settings, and its low maintenance requirements. Additionally, this breaker is especially tailored for three phase applications providing a peace of mind to the user.
