Review ABB Lot Of 20double Pole Bolt on Breaker

The ABB THQB2120 is a 20 amp double pole bolt-on breaker designed for use in electrical distribution boards and panels. This breaker is manufactured by ABB, a global leader in power and automation technology, ensuring high-quality and reliability.

The THQB2120 is a double pole breaker, meaning it can handle two circuits simultaneously with separate trip units for each pole. This makes it an ideal solution for distributing power to multiple loads or circuits while ensuring circuit protection. Each pole has a current rating of 20 amps, allowing it to handle moderate electrical loads with ease.

The bolt-on design of the THQB2120 enables easy installation in busbar systems, with no additional mounting required. The breaker is secured in place by screws that bolt onto the busbar. This design not only simplifies installation but also ensures a robust and secure connection.

The THQB2120 features a tripping mechanism that automatically disconnects the circuit when the current flow exceeds the rated capacity. The breaker trips quickly and accurately, providing reliable circuit protection against overloads and short circuits. The breaker's trip units are independently adjustable, allowing for customized settings for each pole to suit specific application requirements.

The breaker's contacts are made of copper alloy, ensuring excellent conductivity and long-lasting performance. The contacts are also designed to minimize contact resistance, reducing energy loss and ensuring efficient power transfer.

The THQB2120 is designed with safety in mind, featuring a protective cover that shields the live parts from accidental contact. The breaker also complies with various safety standards, including IEC 60947-3-2, ensuring safety for installers and users.

The ABB THQB2120 is a versatile and reliable solution for distributing power and protecting circuits in electrical distribution boards and panels. Its easy installation, accurate tripping mechanism, and long-lasting performance make it an excellent choice for a wide range of applications.

3. May Require Additional Tools: While the bolt-on design is generally easy to install, some customers have reported that additional tools may be required for installation. This could add to the overall cost and time of the installation.

The ABB THQB2120 20A double pole bolt-on breaker is a high-quality option for those in need of a reliable and space-saving breaker for moderate electrical loads. While it may be on the pricier side, the double pole design and ABB brand name offer significant advantages.
