Circuit breakers are devices used to protect electrical circuits from overloads and short circuits. The 8340-F410-K4K1-ALH142-15A is a circuit breaker used to interrupt and close electrical conductors for protection against excessive current. It can also be used to prevent circuit overload and to provide short-circuit protection.

The 8340-F410-K4K1-ALH142-15A is a type of molded case circuit breaker (MCCB) and it is a single-pole magnetic circuit breaker device. It has trip settings and a range of current ratings so it can be used for various applications. It has a box- type construction with a control unit, trip unit, and bus mount terminal.

The 8340-F410-K4K1-ALH142-15A offers a broad range of features such as a compact design, adjustable short circuit protection, adjustable overload protection, electronic thermal memory, adjustable trip value, and energy absorption capability. It also features ground fault protection, adjustable trip characteristics, self-checking touch proof terminals, and adjustable long-term current settings. This circuit breaker is also UL-certified.

The 8340-F410-K4K1-ALH142-15A is used for various applications such as low-voltage power distribution systems, industrial and commercial systems, emergency systems, and electrical distribution systems. In addition to protecting against faulty wiring, this circuit breaker can also be used to protect against overloads, short circuits, ground faults, and current harmonics.

The working principle of the 8340-F410-K4K1-ALH142-15A is that it relies on a thermal-magnetic trip unit to sense and respond to overcurrent conditions. When an overcurrent is detected, the mechanical tripper will open and disconnect the current. This is done by heating the bi-metal strip in the trip unit, which causes the closing of the contact points. It is this disconnection that prevents the current from overloading the circuit and the device is then reset after the fault has been cleared.

In conclusion, the 8340-F410-K4K1-ALH142-15A is a type of circuit breaker used to protect electrical circuits from overloads and short circuits. It can be used in a variety of applications and has a range of current ratings. It works by relying on a thermal-magnetic trip unit to sense and respond to overcurrent conditions, thus preventing an overload. This circuit breaker offers a range of features such as adjustable short-circuit protection, adjustable overload protection, and adjustable trip values.
