The SU3C40AC is an intelligent three-phase automatic circuit breaker used to help protect equipment against overcurrents and short circuits or to shut off a circuit in the event of an emergency. The SU3C40AC is available in both NEMA and UL50/60 ratings, with protection ratings up to 600V and 100A. Additionally, the circuit breaker has an integrated relay, allowing for easy detection and communication of circuit status.

The SU3C40AC is well-suited for a variety of applications, particularly in solar and photovoltaic (PV) systems, light commercial applications, and industrial equipment. The device is also designed for use in sensitive equipment, such as medical instruments, where damage due to excessive current flow or short circuits must be avoided. The integrated relay also makes the SU3C40AC useful in remote monitoring applications, where the device can be used to provide status and alarm information.

The SU3C40AC is a three-phase automatic circuit breaker that is able to detect an overcurrent or short circuit on any of the three phases in a system. Once a fault is detected, the breaker trips, cutting off power to the device being protected. The circuit breaker can be manually reset after the fault is resolved. The adjustable trip current, temperature compensation, and adjustable times delay on trip, as well as the integrated relay, make the SU3C40AC ideal for many applications where a flexible and reliable circuit breaker is needed.

The SU3C40AC works by sensing the voltage and current levels in each phase and then tripping the breaker if the current becomes too high, or a short circuit is detected. The breaker uses a combination of an integrated relay and temperature-compensated trip settings to detect and trip on faults. The adjustable trip current settings allow the SU3C40AC to be adjusted to meet the specific requirements of the application. Additionally, the integrated relay can be used to transmit circuit status to an alarm panel or a remote monitoring system.

In addition to the features already mentioned, the SU3C40AC also includes a built-in low energy consumption mode, allowing for improved energy efficiency in applications with sensitive power requirements. The device is also designed to help reduce the risks of dangerous arc faults in industrial, commercial, and residential applications, as well as providing safe, reliable service in mission critical applications.

In conclusion, the SU3C40AC is an intelligent three-phase automatic circuit breaker that is well suited for a variety of applications. Its adjustable trip current, temperature compensation, and adjustable times delay on trip, as well as the integrated relay, make it an ideal choice for solar and photovoltaic (PV) systems, light commercial applications, industrial equipment, and mission-critical applications. Additionally, the integrated relay and low energy consumption mode make it suitable for remote monitoring applications and for energy-sensitive environments.
