Circuit Breakers

CA2-BO-46-640-121-D is a circuit breaker belonging to the CA2BM range of devices. It is made up of two distinct components; a UL-listed aM and a disconnection switch.

This two-piece arrangement gives it several advantages over a standard circuit breaker, such as the ability to break or make a circuit faster, as well as an increased safety factor when dealing with high-power electrical loads. The maximum rated current of the CA2-BO-46-640-121-D is 40A, and it can handle both AC and DC voltages. It fits into a standard D-frame enclosure.

Application Field

The CA2-BO-46-640-121-D is designed for motor protection applications. It is suitable for use in industrial automation, pump control, machine tool, and other applications.

It is particularly effective in applications where it is important to quickly activate or break an electrical circuit, such as in emergency shut-downs and overload protection. Additionally, it can be used to protect against power surges and short circuits.

Working Principle

The CA2-BO-46-640-121-D works by combining an aM and a disconnect switch in one device. The aM works to detect electrical overloads and open the circuit, while the disconnect switch is used to close the circuit and deenergize the motor.

When an overload is detected, the aM will open the circuit to disconnect the motor’s power supply and prevent it from overloading or short-circuiting. Once the overload is cleared, the disconnect switch will close the circuit and the motor can be re-energized.

Conclusion

The CA2-BO-46-640-121-D is an innovative circuit breaker designed to provide reliable protection for motor applications. By combining an aM and a disconnect switch in one device, it is able to quickly activate or break an electrical circuit, making it ideal for emergency shut-downs and overload protection.
