BQ1B020

The Siemens BQ1B020 is a well-engineered molded case circuit breaker that provides essential overcurrent protection in electrical systems. Constructed as a single-pole unit, it is rated for a current of 20 Amps and can handle up to 120 Volts AC, making it suitable for a variety of user applications. The design ensures a robust interrupting capacity of 10 kA, which is crucial for safeguarding circuits against overloads and short circuits.

This circuit breaker features a Type B trip curve, making it appropriate for devices with inrush currents such as motors. It operates efficiently at a frequency of 60 Hz, ideal for standard electrical systems. The panelboard mounting allows for a straightforward installation process, while the compact dimensions of 1 inch in width, 3.5 inches in height, and 2.5 inches in depth facilitate its integration into tight spaces.

The unit includes load side lugs for terminal connections, with a specified torque of 2.8 Nm for securing the wires. Its operating temperature range spans from -40°C to +70°C, allowing it to function reliably in both cold and warm environments. It's designed to accommodate wire sizes of 14 AWG, enhancing flexibility during installation.

The trip mechanism of this breaker operates on a thermal-magnetic principle, combining both thermal and magnetic response to ensure prompt disconnect during fault conditions. A toggle switch handle provides a user-friendly interface for switching between ON, OFF, and TRIP positions, facilitating convenient operation and monitoring.
