Circuit Breakers

Circuit breakers are electrical devices designed to protect electrical circuits from being overloaded. They are used to guard against short circuits, overvoltage, and overcurrent. The current rating of a circuit breaker is typically dictated by its physical size and the amount of current it can safely handle before tripping. The size of a circuit breaker is also impacted by its voltage rating, as higher voltage requires a larger circuit breaker.

Circuit breakers come in two main types – thermal magnetic and AC only. Thermal magnetic breakers use a magnet to actuate the contacts that can interrupt a circuit at high current levels. AC only breakers, which are used in specific high-current applications, are specifically designed for alternating current (AC) and can interrupt a circuit at higher speeds than thermal magnetic circuit breakers.

9103003500 Application Field and Working Principle

The 9103003500 thermal-magnetic circuit breaker from Eaton is a UL 489-listed device used for residential, commercial and industrial applications. With an AC rating of 440 volts and a maximum current capacity of 6,000 amperes (Amp), it is suitable for applications requiring high current protection.

The 9103003500 operates using thermal-magnetic technology. This technology relies on two different processes to protect the circuit against overloads or short circuits. The first process is thermal, which uses a bimetallic strip to sense the current flow and generate heat. When a fault occurs, the heat created by the current flow causes the bimetallic strip to open the circuit. The second process is magnetic, which uses an electromagnetic field to actuate the contacts and open the circuit at higher current levels.

The 9103003500 is designed with an adjustable trip setting to provide flexibility in adjusting the breaker’s trip point, depending on the protective device needed. It also features a feather touch handle, which provides easily identifiable tactile feedback. Additionally, it is provided with a padlocking provision, which allows for additional security for the breaker’s operation.

Eaton’s 9103003500 thermal-magnetic circuit breaker provides reliable, localized protection for applications requiring high current protection. With its adjustable trip setting and padlocking provision, in addition to its ease of use, it is an ideal device for both industrial and commercial applications.
