1278930000

Circuit breakers protect electrical infrastructure from damage caused by power spikes, overcurrent and excess voltage events. The 1278930000 circuit breaker is a type of current interruption device used to protect AC systems from overloads and short circuits. 1278930000 circuit breakers are most commonly used in industrial and commercial settings and feature adjustable trip mechanisms for fine-tuning overload protection, dual-action operation that allows for both testing and resetting of the circuit breaker and automatic re-closing of the circuit breaker if reset is successful.

The 1278930000 circuit breaker is designed to protect AC circuits from overloads and short circuits, as well as to detect any abnormalities in the system such as an overcurrent or an excessive voltage event. When an overload or short circuit occurs, the 1278930000 breaker trips and safely disconnects the circuit, preventing further damage to the electrical system. Once the fault has been identified and corrected, the breaker can be reset, the circuit re-energized and work can resume.

The 1278930000 breaker utilizes a thermal-magnetic cut-off, which means that when the current exceeds the predetermined limits, the breaker trips on its own without requiring input from a power source. The thermal-magnetic cut-off works by using a combination of a bimetallic strip and a magnetic trip coil, which are both sensitive to heat and electromagnetism. The bimetallic strip expands or contracts in response to heat, while the magnetic trip coil is sensitive to the increasing current, which in turn creates a magnetic field. This buildup of magnetic force causes the trip coil to break the connection and trip the circuit breaker. If a short circuit occurs, then the current should exceed the limits set by the trip coil, causing it to trip the circuit breaker.

The 1278930000 circuit breaker is highly reliable and versatile, making it particularly suitable for use in industrial and commercial settings. The adjustable trip mechanism allows the trip current to be set, allowing the protection of all types of devices ranging from light switches, fans and large industrial motors. Additionally, the use of dual-action operation allows the breaker to both test and reset the circuit, eliminating the need for manual resetting. Furthermore, the automatic reclosing feature allows the circuit breaker to close upon successful reset and reconnect the system, allowing work to resume without disruption.

The 1278930000 circuit breaker is an effective and reliable piece of electrical equipment, offering superior protection against power surges and overloads. With its adjustable trip mechanism and dual-action operation, it is the perfect choice for a wide range of applications and its automatic reconnect feature ensures uninterrupted power supply to the circuits. The 1278930000 circuit breaker is a must-have for any industrial or commercial application and is sure to provide years of reliable service.
