2210-S221-P1T1-H0-8A Application Field And Working Principle

Circuit breakers are extremely important components in the electrical wiring of a variety of establishments. Different types of circuit breakers offer a range of features and protections. The 2210-S221-P1T1-H0-8A circuit breaker is a specific type of device used to protect against short circuits, overloads, and ground faults in residential and other light commercial wiring systems. This article takes a closer look at the application field and working principle of the 2210-S221-P1T1-H0-8A circuit breaker.

Application Field of the 2210-S221-P1T1-H0-8A Circuit Breaker

The 2210-S221-P1T1-H0-8A circuit breaker is designed for either a conduit or a branch line circuit. It is ideal for use in residential and light commercial applications such as houses, schools, laboratories, and other light commercial wiring systems. This type of circuit breaker is manufactured in accordance with the UL and CSA listing standards, meaning it is approved for use in the U.S. and Canada. The 2210-S221-P1T1-H0-8A circuit breaker is a single-pole breaker suitable for applications where one hot wire is required.

The 2210-S221-P1T1-H0-8A circuit breaker is a single-pole, thermal magnetic, semiconductor-tripped circuit breaker. It is rated current of 8A, and is designed for residential circuits supplying 120/240V 60Hz AC. Its direct-acting trip unit functions in both overload and short circuit conditions, and its currents up to 30,000A are interruptible. The breaker can also be used in multiple circuits with a maximum of six breakers in any one circuit. This allows for the breaker to be installed in any of the following positions within a circuit: At the origin of the circuit, in the middle of the circuit, or at the end of the circuit.

Working Principle of the 2210-S221-P1T1-H0-8A Circuit Breaker

In order to maximize protection, the 2210-S221-P1T1-H0-8A circuit breaker is designed with two separate protective mechanisms. The first of the two is the direct acting trip unit, which is activated whenever the instantaneous current reaches a preset value, and interrupts the circuit. The second mechanism is the thermal magnetic function, which is activated when the long-term current reaches a preset value, and also interrupts the circuit. This dual-protective design allows the circuit breaker to be highly effective in a wide variety of conditions ranging from overloads to short circuits.

When an overload or a short circuit occurs, the direct acting trip unit is activated and the circuit is interrupted. The device’s thermal magnetic function is triggered if the overload or short circuit lasts for more than five seconds. Once the trip unit has been activated, the breaker will not reset until the fault has been cleared. The breaker will then be ready to be powered on again when the circuit is OK.

In order to ensure the efficiency and reliability of the breaker, the 2210-S221-P1T1-H0-8A comes with a UL listed time-delay feature. This feature allows for the breaker to detect an overload or a short circuit, yet not immediately react. The time delay feature helps to prevent false trips, as it allows consumers the time to rectify the fault without the breaker resetting. In addition, the thermal magnetic unit also ensures that the breaker does not reset immediately after a fault has been cleared. This feature, combined with the UL time delay feature, ensures that the breaker will stay in an open position even if the overload or short circuit has been cleared.

Conclusion

In conclusion, the 2210-S221-P1T1-H0-8A circuit breaker is a single-pole, thermal magnetic, semiconductor-tripped circuit breaker designed for either a conduit or branch line circuit. It is ideal for use in residential and light commercial wiring systems. This type of circuit breaker features a UL listed time delay feature, and is a highly efficient and reliable device due to its two-separate protection mechanisms. The device is UL and CSA listed, meaning it is approved for use in the U.S. and Canada.
