IntroductionThe 4430.2238 is a circuit breaker designed to protect a residential or light commercial electrical system from short circuits, overloads, and ground faults. This breaker has a voltage rating of either 120/240 volts or 277/480 volts and is suitable for single-phase applications with a maximum of 200 amperes. The 4430.2238 is also approved by UL 489 and CSA C22.2 for use in a variety of applications, including motor branch circuits, lighting branch circuits, and non-motor-astable loads.Application FieldThe 4430.2238 is suitable for use in residential and light commercial applications. This circuit breaker provides protection against short circuits, overloads, and ground faults. These are all common potential hazards in electrical systems, and the 4430.2238 circuit breaker helps to protect against these issues.In addition to its primary use of providing protection against short circuits, overloads, and ground faults, the 4430.2238 can also be used as a manual shut-off switch. This is useful for disconnecting power from an electrical system, such as for maintenance or repairs. The 4430.2238 is also approved as a Lighting Contact Switch (LCSW) and comes with a switch position indicator to denote ON/OFF setting.Working PrincipleThe 4430.2238 circuit breaker works by monitoring the current running through the system. If the circuit breaker detects an overload, such as from a short circuit, it will shut off the circuit to protect it from further damage. The circuit breaker will also shut off the circuit when the current exceeds the predetermined current overload setting.The trip mechanism for the 4430.2238 is a thermal magnetic trip unit. This type of trip unit uses both heat and magnetism to detect an overload. When an overload occurs, the thermal magnetic trip unit will generate an electromagnet that will open the circuit. The thermal magnetic trip unit will also reset itself after the overload is cleared.ConclusionThe 4430.2238 is a circuit breaker that is used to protect electrical systems from short, overloads and ground faults. It has a voltage rating of either 120/240 or 277/480 volts and is suitable for single-phase applications. The 4430.2238 is also UL 489 and CSA C22.2 certified and can also be used as a manual shut-off switch. The trip mechanism for this circuit breaker is a thermal magnetic trip unit that uses both heat and magnetism to detect an overload and shut off the circuit.
