Circuit breakers are safety devices used in electrical systems to prevent a fault from causing a power outage or other catastrophic event. The CB1921-10 is a type of circuit breaker specifically designed for medium voltage applications. It provides wide-ranging protection against electrical faults and is often used in industrial and power grid applications.

The CB1921-10 is an industry standard, three-pole circuit breaker rated at 10kV. It is designed to respond quickly and efficiently to electrical faults, interrupting the faulty current within a few milliseconds. This helps to protect the system and power grid from damage or disruption due to overloads and short circuits.

The CB1921-10 is equipped with a range of features to improve protection and reduce downtime. These include adjustable trip settings and a manual reset button, allowing users to quickly reset the circuit breaker in the event of an outage. The breaker also offers the option of arc-flash protection, which helps reduce the risk of fire and electrocution in the event of a fault. The breaker also has mechanical interlocks to guard against double-tripping.

The CB1921-10 is designed for use in medium voltage applications that involve both alternating current (AC) and direct current (DC) power. The breaker is capable of operating at a range of different voltages and is suitable for applications up to 10kV. The breaker is also designed to tolerate signals of different frequencies and can operate at up to 60Hz.

The CB1921-10 utilizes a magnetic field-operated contactor. This device has a contact set that is opened and closed by a magnetic field. When an electrical fault occurs, the contact set rapidly separates, thereby cutting off the flow of current and preventing damage to the system. The CB1921-10 is capable of interrupting up to 10kA of fault current, making it suitable for a wide range of applications.

The CB1921-10 offers several other features to improve its performance and operational efficiency. It is equipped with a vibration sensor that allows it to detect any loose connections in the system. This helps improve system reliability and protects against damage from intermittent faults. The breaker is also capable of monitoring the health of the device itself, improving its diagnostics and self-maintenance capabilities.

The CB1921-10 is designed for use in medium voltage applications such as power distribution and industrial systems. It is highly reliable and offers a range of features to protect the system from electrical faults and overloads. The magnetic field-operated contactor ensures fast and reliable interruption of the faulty current, while the other features improve system reliability and reduce the risk of downtime. The CB1921-10 is a reliable and versatile circuit breaker that is suitable for a wide range of applications.
