IULDHK111-1-65-4.00-B-91

Circuit Breakers are one of the most essential and widely used safety devices in the electrical industry. They are typically used to switch electrical connections and to provide protection from overloads and short circuits. The IULDHK111-1-65-4.00-B-91 is a specific type of circuit breaker that is used in a wide range of applications, along with its own unique working principle.

The IULDHK111-1-65-4.00-B-91 is a fixed-mounted type of double leg circuit breaker with an interrupting rating of 65 kA (kilo-Amps). This type of circuit breaker can be used in a variety of applications including residential, commercial, and industrial spaces. It is UL (Underwriters Laboratories) listed and carries a CSA (Canadian Standards Association) listed rating. The size and design of the IULDHK111-1-65-4.00-B-91 is a combination of IUL 411-1, UL 489B, and HACR rated breakers.

The working principle of the IULDHK111-1-65-4.00-B-91 is a fairly simple one. When an overload or a short circuit occurs, the breaker ‘trips’ or turns off the power supply. This is done by a thermal-magnetic mechanism which consists of two parts; the thermal element and the magnetic element. The thermal element is a bimetallic strip that is heated by the current, and bends when the current increases past a certain level. This motion then triggers the magnetic element which pulls the trip shaft and cuts off the power supply.

The IULDHK111-1-65-4.00-B-91 is also equipped with a manual reset button which can be used to restore power after the breaker has tripped. This reset button can also be used to reset the breaker after an overload or short circuit has been removed. Additionally, this type of circuit breaker also has a visual indicator which provides an on/off indication of the breaker’s operation.

The IULDHK111-1-65-4.00-B-91 is a highly reliable and powerful double leg circuit breaker that is suitable for a wide range of applications. Its thermal-magnetic tripping mechanism ensures a rapid response time and it is also equipped with a manual reset button and visual indicator for added safety and convenience. This type of circuit breaker is UL and CSA listed and provides a safe and effective interruption of electrical power in both residential and commercial spaces.
