Circuit breakers are designed to protect electrical circuits from short-circuits and overloads. The 285-111-30758-1 circuit breaker is a three-pole miniature circuit breaker with thermal-magnetic trip units. The trip unit is UL listed and CSA certified for use in circuits up to 250Vac.

The 285-111-30758-1 circuit breaker features a short-circuit rating of 10kA at 250Vac with a breaking capacity of 35kA at 250Vac. This circuit breaker also has a ground fault current interruption ability at 10kA for use as a ground fault interrupt device. The 285-111-30758-1 circuit breaker features a neutral-, ground- and line-to-ground trip point adjustment range of 50-500mA. The adjustable settings are designed to help ensure the circuit breaker will trip at the correct point for the given application.

This circuit breaker is suitable for use in residential, commercial, and industrial applications. It is commonly used as a disconnect switch in AC-powered motor controllers and motor starters. It is also used as a service entrance and main disconnect switch. Additionally, the 285-111-30758-1 circuit breaker can be used as a branch circuit breaker in lighting and power systems.

The 285-111-30758-1 circuit breaker operates using a combination of thermal and magnetic principles. The trip unit is designed to detect excessive temperature and current within the circuit. The thermal element is designed to trip the circuit breaker when an excessive build up of heat is detected. The magnetic element is designed to trip the circuit breaker when an excessive current is detected. The trip unit is designed to operate reliably and safely under normal and fault conditions, protecting people and equipment from harm.

In the event of a short-circuit, the magnetic trip element will sense and trip the circuit breaker. The thermal element will then activate and trip the circuit breaker to prevent the circuit from being overloaded and permanently damaged. The 285-111-30758-1 circuit breaker also features a neutral-ground fault interrupter. In the event of a neutral-ground fault, the interrupter will sense and trip the circuit breaker, preventing electrical shock.

The 285-111-30758-1 circuit breaker is designed to provide reliable and safe circuit protection for a variety of applications. The adjustable trip point settings let users adjust the trip points for optimal protection under varying operating conditions. The combination of thermal and magnetic trip elements helps to ensure the circuit breaker will trip at the correct point for the given application. In the event of a short-circuit or overload, the 285-111-30758-1 will trip to prevent permanent damage to the circuit.
