1658-G21-00-P10-D01-30A

# Introduction The 1658-G21-00-P10-D01-30A is a circuit breaker switch, which is designed for the protection and control of electrical circuits in industrial and residential applications. This circuit breaker is designed for general purpose and space saving. This device is rated for 15A (14KW) and 10A (7.2KW) for end-of-line and starter conditions. The working principle behind the 1658-G21-00-P10-D01-30A is simple. When a short or overload condition occurs, the breaker contacts open, isolating and thereby protecting the circuit from further damage. When the overload or short condition subsides, the contacts can easily be reset to their initial state to restore power to the circuit. # Application FieldThe 1658-G21-00-P10-D01-30A is suitable for general-purpose and space-saving applications in industrial and residential environments. This device is rated for 15A (14KW) and 10A (7.2KW) for end-of-line and starter conditions, respectively. The switch is also suitable for power distribution, control circuits, motor control, generator protection, and lighting control applications. Additionally, the circuit breaker switches may be used in applications requiring a higher short circuit breaking capacity. The switch is most often used in applications where protection against short-circuits, overcurrent, and overloads is required. It can be applied to AC and DC devices, such as air-conditioners, fans, air compressors, washing machines, motors, etc. # Installation RequirementsThe circuit breaker should be installed in accordance with national wiring regulations. It should be mounted to a mounting panel or to a surface area with a minimum of 10 in-lbs. of torque. The circuit breaker must be securely fastened to the panel to ensure vibration and shock will not interfere with the operation. For added protection, an insulation cover should be used to prevent foreign objects from entering the circuit breaker switch.Additionally, it is recommended that the circuit breaker be installed in a dry and well-ventilated location in order to facilitate adequate cooling and prolong the life of the circuit breaker. # Working PrincipleThe 1658-G21-00-P10-D01-30A employs a thermal-magnetic trip mechanism to provide protection against overloads and short circuits. The mechanism works by sensing the current flowing through the circuit breaker switch, and then activates the tripping mechanism to open the circuit breaker contacts when a set current is exceeded. When a short or overload condition is present, the trip mechanism operates to interrupt the current flow and then releases the breaker contacts to the “open” position. This function will provide protection to the circuit and should be reset manually by pressing the reset button. The 1658-G21-00-P10-D01-30A also features an adjustable trip current setting. This setting can be adjusted to provide more flexibility in the operation of the circuit breaker and to ensure that the circuit breaker will trip at the correct current for the application. The current setting can be adjusted by turning a dial located on the face of the breaker. Refer to the manufacturer’s instructions for details on how to set the current setting. # ConclusionThe 1658-G21-00-P10-D01-30A circuit breaker switch is designed for general-purpose and space-saving applications in industrial and residential environments. It is rated for 15A (14KW) and 10A (7.2KW) for end-of-line and starter conditions, respectively. The working principle of the switch involves a thermal-magnetic trip mechanism, which senses the current flowing through the circuit breaker switch, and then activates the tripping mechanism to open the circuit breaker contacts when a set current is exceeded. The device should be appropriately installed according to the wiring regulations and is recommended to be installed where adequate cooling can be ensured.
