Circuit breakers are protective devices used to limit electrical faults. With various types of circuit breaker designs, one particular circuit breaker, the JTMP-2-1RLS4-39244-2, has its own application field and working principle.

This 2-pole miniature circuit breaker has a modular design and features a fault current limiting shunt trip, with adjustable settings for overload, short-circuit, and ground-fault protection. It can protect both AC and DC circuits under normal and faulted conditions, however, since it can only handle one single fault type at a time, it is not the best solution for multiple simultaneous fault conditions.

The JTMP-2-1RLS4-39244-2 circuit breaker is primarily used in residential, commercial, and industrial applications. It is especially useful in installations where the circuit breaker enclosure must remain visible or easily accessible, such as in outdoor circuit breakers, where limited space is available. It is also very cost-efficient and has a lifespan of up to 10 years.

The working principle of the JTMP-2-1RLS4-39244-2 circuit breaker is based on the use of an electromagnetically-operated armature. When a fault occurs, the armature is pulled down, causing the breaker contacts to move apart, which in turn interrupts the power flow and trips the circuit breaker. The fault current can be eliminated by resetting the breaker to its “closed” position.

The JTMP-2-1RLS4-39244-2 circuit breaker offers many benefits, not the least of which are an adjustable overload setting, a high level of safety, and an overall cost savings. With adjustable overload settings, a user can lower the sensitivity of the breaker in order to avoid nuisance tripping. It also provides a level of safety and assurance in that if a fault does occur, the breaker will automatically trip off and shut down the circuit, avoiding further damage or injury. Lastly, the overall cost savings of using this specific circuit breaker are greatly beneficial, as it provides superior albeit cost-efficient protection.
