Circuit breakers are a type of switch designed to interrupt the flow of electricity in response to an overcurrent caused by an increased load or a short circuit. The IEL112-28491-3-V is a circuit breaker which is designed to operate when current flow exceeds a certain level. This circuit breaker is typically used in residential and commercial applications to protect building wiring from an overload or potentially hazardous short circuit conditions.

The IEL112-28491-3-V circuit breaker utilizes a thermally-operated tripping mechanism, which is temperature sensitive. When the current drawn by the protected circuit increases, the temperature of the trip mechanism increases as well. When it reaches a predetermined level, it triggers the circuit breaker’s mechanism, which interrupts the current and breaks the connection. This is referred to as “thermal trip”, as it operates due to the heat generated from the increased current.

The application field for the IEL112-28491-3-V circuit breaker includes residential and commercial buildings, as well as industrial processes. It is rated at 20A and 240V (or 20A and 120V), making it suitable for most domestic and business applications such as interior circuit protection, which is the most common application. It is also used in some industrial processes to protect control circuits, motors, relays, and other devices from damage due to an overload or short circuit.

Overall, the primary purpose of the IEL112-28491-3-V circuit breaker is the protection of electrical systems from an overcurrent or short circuit condition. It has a wide range of uses and applications ranging from residential and commercial buildings to industrial systems. It operates through a mechanism which is temperature sensitive and uses a thermal trip, which interrupts the flow of electricity when it reaches a certain current level.
