NFSHLF19X25 is a basic type of non-fused self-healing load-break switch manufactured by Schneider Electric. It is mainly used in the LV electrical distribution systems for remote operation, reinstatement of supply, automatic transfer and maintenance services. It has been designed to meet the requirements as specified in the IEC 60947-2 standard.

The NFSHLF19X25 has two poles, with a rated current of 25A and a rated voltage AC400V. It has a disconnecting function both for short-circuit and overload protection, and a differential protection for motor protection against motor failure due to overload and short circuit. The NFSHLF19X25 also has a self-healing mechanism, which means that it can automatically repair any damage it\'s internal components while remaining in service, without the need for manual intervention.

The NFSHLF19X25 is mainly used in commercial, industrial and residential installations, such as distribution networks, lighting systems, air conditioning, energy production and telecommunication systems. It can also be used as a circuit breaker in emergency systems and power quality systems, and as a switch-disconnecting point in data centers.

The NFSHLF19X25 is based on a set of patented technologies that enable the self-healing mechanism, as well as its overload protection and fine-tuned differential protection. It utilizes a directional performance concept, which allows the device to identify and detect internal damage and quickly respond to the problems. This allows it to maintain efficient operations even under fault conditions, and quickly revert to normal operations once the fault is cleared.

The device is based on a combination of power electronics and semi-conductors, that are connected to an internal diagnostic processor, which in turn is connected to the communications, connections and outputs. The processor enables the device to monitor its current, and detect any anomalies or damage that it may have sustained. It is also able to keep a log of the current performance of the device, so that its behaviour can be evaluated for future maintenance and service.

The self-healing mechanism of the NFSHLF19X25 is based on a special insulation material, which is able to continuously adapt its own characteristics to suit the current requirements. This results in a superior insulation performance and a longer life of the switch. As a result of the self-healing characteristics, the NFSHLF19X25 is able to will maintain a reliable and high-performance service for many years, even under conditions of repeated external electrical disturbances.

In conclusion, the NFSHLF19X25 is a versatile load-break switch, which combines a very reliable self-healing mechanism with a high level of protection and versatile communication and control capabilities. This makes it an ideal solution for many electrical installations, both in commercial and residential applications.
