Circuit breakers are safety devices used in electrical circuits to protect against overload and short circuit conditions. The 1428057-1 circuit breakers are a type of circuit breaker designed to enable the operation of electrical circuits in hazardous, high noise, and high current areas.

This circuit breaker is used as an effective accident prevention measure to protect personnel and equipment from electrical overcurrent and short-circuiting. It is a single-pole circuit breaker that features an internal shutter mechanism that prevents a dual-directional current flow (on/off) in the electrical circuit when a significant surge or overload occurs. It is designed to be used in general purpose AC circuits up to 400 volts, with a nominal current rating of up to 60 amperes.

This circuit breaker provides reliable protection from various forms of electrical overcurrents, such as: short-circuits, ground fault currents, or overvoltage surges. It also meets UL489, UL1077 and UL1042 requirements for short-circuit protection and has a high interruption capacity (mechanical, electrical and thermal) for reliable performance. An integral thermal magnetic trip device with adjustable long-delay trip characteristics is incorporated in the design of the circuit breaker to enable proper timing of circuit overcurrents.

The 1428057-1 circuit breaker has a wide range of application fields, such as: industrial plants, electrical control panels, pumps, etc. This circuit breaker is suitable for use in power plants, motor control centers, and as an emergency back-up circuit breaker in hazardous areas. It is also used to protect electrical components and equipment against over-current situations in factories and other industrial locations. This circuit breaker can be used in any location requiring electrical protection, including marine and aircraft applications.

The operating principle of the 1428057-1 circuit breaker is simple. When the current in the circuit exceeds the maximum allowable rating, the internal trip device will open the circuit and shut down the electrical system. This action helps prevent the possible damage and hazards associated with overcurrent situations. The trip device is adjustable and can be calibrated to trip at any desired current.

The 1428057-1 circuit breaker is a reliable, safe and easy-to-maintain device that provides reliable protection from various forms of electrical overcurrents. This type of circuit breaker is suitable for any location or application requiring reliable and secure electrical protection. It is also a cost effective solution for those who require a reliable and safe circuit breaker with a long service life.
