APL1-1911-3

APL1-1911-3 application field and working principleCircuit breakers are an essential safety device in any electrical system. They are designed to open an electrical circuit if too much current flows through it. This prevents potential overloading or short-circuiting which can lead to fires, explosions and other potentially dangerous situations. The APL1-1911-3 is an AC-DC circuit breaker which is designed for low voltage, high current applications.The APL1-1911-3 is a double pole breaker that features two trip mechanisms in a single enclosure. It is designed to trip within a single cycle of input voltage, making it an ideal choice for use in sensitive applications. The breaker has a rated voltage of 250V AC and can operate up to 125A continuous current. It is UL-approved and designed for use as a main-line device or branch-circuit over-current protection.The APL1-1911-3 utilizes a two-stage trip mechanism. The first stage is a bimetallic trip which trips the breaker when the input current reaches its rating. The bimetal snaps quickly when enough heat is generated within the device. The second stage is a thermal trip. This uses heat from the first stage to slowly open the contacts, providing a more gradual trip action and helping to reduce arcing and limit the amount of energy that is temporarily stored before the breaker trips.The APL1-1911-3 is suitable for use as a branch circuit breaker, main-line circuit breaker or as an over-current protection device. It can be used in a wide variety of applications, making it an ideal choice for commercial, residential, and industrial installations. This dependable and UL-listed breaker is sure to provide reliable protection and help keep your electrical system safe.
