Circuit breakers are an integral part of any electrical system. They are responsible for protecting the system’s components by breaking the circuit when the current reaches a predetermined level, thus preventing the build-up of excess current. The LEG66-39991-10-V is a type of circuit breaker that is suitable for applications with extremely high current levels. It is designed to provide superior protection from potential electrical arcs and overloads. The LEG66-39991-10-V is designed to meet the requirements of the UL 489 Standard for safety requirements for molded-case circuit breakers. It is suitable for standard trips up to a maximum of 220V AC. This model also offers a large number of optional trips ranging from 18V AC to 288V AC. The LEG66-39991-10-V employs a thermal-magnetic trip unit. This trip unit consists of two components: a heat element and a magnetic element. The heat element is an elongated piece of metal that has two electrical connections attached to it. When the current rises beyond a predetermined level, the heat element’s resistance begins to increase, thus creating a thermal imbalance. This imbalance then causes a movement in the core of the thermal-magnetic trip unit which ultimately causes an electrical arc to be formed. The second component, the magnetic element, is a coil of wire that wraps around the heat element. When a current is applied to the coil, it generates a magnetic field that interacts with the heat element. This interaction causes the core of the trip unit to move and this movement causes an electrical arc to be formed. The LEG66-39991-10-V is designed to provide superior protection in a range of high-current applications. It is capable of interrupting currents up to 10,000A and is suitable for use in hazardous environments such as industrial installations, power plants and marine applications. In addition, the LEG66-39991-10-V is also suitable for protection against overloads and short circuits as well as long delay time applications. The LEG66-39991-10-V also features excellent thermal and magnetic stability, as well as short circuit protection from currents up to 5000A. It is lightweight and compact, making it easy to install in tight spaces. The LEG66-39991-10-V also comes with a large range of accessories such as mounting plates, cable kits and reset handles. The LEG66-39991-10-V is a highly reliable and versatile circuit breaker that can provide superior protection for a wide range of high-current applications. It is designed to meet the requirements of UL 489 and is suitable for interrupting currents up to 10,000A. The LEG66-39991-10-V is also lightweight and compact and comes with a range of accessories for easy installation.
