CB181P-150

Circuit breakers are incredibly important pieces of machinery. They are used as an important part of electrical systems to protect individuals, buildings, and equipment from over-current or short-circuit events. It is important to understand what type of circuit breakers are available and how they work. The CB181P-150 circuit breaker is a type of low-voltage, miniature circuit breaker with a single pole configuration.

The CB181P-150 circuit breaker is known for its compact size, making it ideal for applications in limited space areas. This circuit breaker is UL 489 listed, meaning it can be used in a wide range of residential, commercial, and industrial environments. Additionally, it is certified for use according to CSA standards, making it suitable for use in Canada as well.

The CB181P-150 circuit breaker is designed for both AC and DC applications and is rated for a maximum current of 150A. It is designed with a cryolite trip unit and a double-break, single-phase contacts. The trip unit has an adjustable thermal-magnetic type long trip curve, allowing it to be easily modified to fit different applications. This trip unit can also be used in a motor control center to protect small to medium sized motors.

The CB181P-150 circuit breaker is suitable for use in branch circuits and motor control applications. It can also be used to backfeed a generator, as well as protect motors in three-phase, split-phase, and capacitor-start/run systems. Additionally, it can also be used in applications where undervoltage, instantaneous, and ground fault protection are required.

The working principle of the CB181P-150 circuit breaker is based on thermal-magnetic technology. It works by using an adjustable bimetallic element along with a magnetic trip unit to respond to over-current and short-circuit events. The bimetallic element is activated when an over-current or short-circuit event occurs, releasing a trip actuator that activates the contacts, thus disconnecting power from the circuit. The adjustable thermal-magnetic long trip curve setting can be adjusted to match the application and properly protect the circuit.

The CB181P-150 circuit breaker is designed specifically for applications where space or size is limited. Its compact size makes it suitable for branch circuits, motor control centers, motor control applications, and back-up generator feeds. Additionally, its adjustable thermal-magnetic trip unit provides reliable protection against over-current and short-circuit events. Combined with its safe and reliable operation, the CB181P-150 circuit breaker is an ideal choice for residential, commercial, and industrial applications.
