TMAX series - ABB moulded case circuit breakers
Tmax is ABB's molded case circuit breaker with a current of up to 630A. It exhibits excellent performance in a smaller size than similar products on the market. It can be flexibly equipped with electronic or thermal-magnetic trippers to meet various protection function requirements.
Features:
◆ Double insulation: Double insulation structure ensures the safety of the operator during normal operation of the device;
◆ Reliable operation: The operating handle accurately indicates the position of the circuit breaker's moving contact, ensuring safety and reliability;
◆Isolation performance: The circuit breaker can guarantee the isolation of the circuit in the disconnected position, in line with the IEC 60947-2 standard;
◆ Protection class: The following table lists the guaranteed protection class of the Tmax circuit breaker, in accordance with the IEC 60529 standard:
1) After correct installation;
2) During installation of electrical accessories;
3) Also suitable for front panel operating mechanism and linear rotary handle;
4) Applicable to T1-T6;
The protection grade of the fixed part is IP20. For example, the circuit breaker installed in the switch cabinet adopts an extended rotary handle operating mechanism and installs special accessories on the cabinet door, which can increase the protection grade to IP54 (RHE - IP54);
◆ Current limiting function: The arc extinguishing system used in Tmax circuit breakers enables high short-circuit currents to be cut off very quickly.
S200 series - ABB miniature circuit breakers
The S200 series is a miniature circuit breaker and residual current action product launched by ABB in response to market demand, which can meet the installation needs of equipment and customers and provide solutions for them, and is widely used in residential, commercial and industrial power distribution occasions.
Features:
◆ Complete series: B/C tripping characteristics, 80A and 100A, the number of poles is available from 1, 2, 3, 4, 1+NA to 3+NA;
◆ General accessories: can be equipped with various accessories of S200 series, which is convenient for stocking;
◆ Global certification: As a globally unified product series, it has mainstream certifications from various countries and regions;
◆ Safe and visible: The "CPI" indicator window on the front of the product, the position of the switch contact is clear at a glance, ensuring the safety of the installer and the user;
◆ Flexible and compact: Inheriting the unique "two-way cylindrical lift terminal" of the S200 series, it can also cooperate with the bottom-mounted auxiliary contacts to realize the ultimate compact solution in which the auxiliary contacts are only 17.5mm wide for single-pole 100A miniature circuit breakers;
◆ Expanding the spectrum: While fully replacing the original S280 80/100 series products, it further extends the scope of the S200 series, making it more efficient and flexible.
EMAX series - ABB frame circuit breakers
The Emax series of air circuit breakers can be divided into 6 models: X1, E1, E2, E3, E4 and E6, with frame currents up to 6300 A. Products E1 - E6, both fixed and withdrawable, have the same height and depth and can be assembled in compact switch cabinets.
Features:
◆ Extraordinary intelligence: The new generation of protection release is equipped with advanced electronic components, which can customize different control and protection schemes;
◆ The new release has many functions, is easy to use, and has important innovations. For example, it is equipped with a brand-new and intuitive operation interface. The user can completely control the entire system by simply pressing a few buttons;
◆ In addition, it has new protection functions and alarm functions, and can be connected to a laptop/notebook computer via Bluetooth technology;
◆ With the standard attachment system developed and manufactured for the new Emax circuit breakers, work becomes easier, more convenient, safer and faster.
