Circuit breakers provide a critical protective function in the electrical distribution system by responding to faults (i.e., short circuits) and other events that could cause safety or damage issues. The device serves to open or close the circuit in order to prevent the further flow of electricity and protect components, systems, and property. The code 483-G111-K1M1-D1S1Z-1A circuit breaker is a molded case circuit breaker, also known as a MCCB. It is designed to prevent large currents from damaging downstream equipment during short-circuit events and any other abnormally high current conditions.
Molded Case Circuit Breakers (MCCBs) are electrical safety devices that interrupt power distribution and prevent electrical overloads and short circuits. They also help to reduce the risk of fires and the possibility of electrocution. In the event of an electrical fault, MCCBs are designed to open rapidly, protecting people, property, and equipment from electrical faults. With their high breaking capacity and trip characteristics, MCCBs provide high-level protection for downstream components, and are therefore an important tool in the electrical safety strategy of any building or industrial facility.
The 483-G111-K1M1-D1S1Z-1A MCCB is part of a full range of UL, CSA, and IEC MCCBs, designed for use in commercial, industrial, and institutional applications. This MCCB provides controlling and protection functions for circuits in three-phase systems up to 600 volts. It is equipped with a thermal-magnetic trip mechanism and offers a range of adjustable trip settings for overload protection of downstream loads. The contact system is built to meet IEC, VDE, and UL requirements, with high-frequency silver contacts for reliability and long life.
The thermal-magnetic trip mechanism of the 483-G111-K1M1-D1S1Z-1A MCCB works by sensing both the current and the temperature of the circuit. This combination of sensing mechanisms enables the MCCB to respond quickly to short-circuit currents, while still allowing the user to set an adjustable current value for overload protection. The thermal sensing element will detect changes in temperature, and if the current limit is exceeded, the MCCB will open and break the electrical circuit.
In addition to protecting against short-circuit faults, the thermal-magnetic trip mechanism also helps to protect against overloads. The MCCB is capable of detecting a variety of overload states, such as overvoltage, undervoltage, asymmetrical load, and other instances of excessive current. Once an overload situation occurs, the MCCB can open the circuit and reduce the potential for damage to the downstream components.
Aside from the thermal-magnetic trip mechanism, the 483-G111-K1M1-D1S1Z-1A MCCB also offers many additional features. These include a padlockable handle, a slow-make feature to reduce inrush currents, padlockable OFF and TEST positions to put the MCCB in a “safe” position, and a neutral terminal for multi-wire applications. Additionally, the MCCB is rated for use in high-ambient temperatures up to 105°C.
The 483-G111-K1M1-D1S1Z-1A MCCB is a reliable and versatile molded case circuit breaker that is designed to provide protection for circuits and downstream components against short-circuits and overloads. It is a simple and effective device that offers reliable protection for a wide variety of applications and provides high-level safety for personnel in the event of an electrical fault.
