NSX100-160-250 Electric Compact New Original Schneider Circuit Breaker

Schneider Electric provides switching devices capable of closing, carrying, and interrupting current under normal circuit conditions, and capable of closing, carrying, and interrupting current under abnormal circuit conditions (including short-circuit conditions) within a specified time. They primarily provide comprehensive solutions, a full range of products and components, and attentive service to customers worldwide.

Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers according to their application range. The distinction between high and low voltage is somewhat blurred; generally, those above 3kV are considered high-voltage electrical appliances. Low-voltage circuit breakers, also known as automatic switches or commonly referred to as "air switches," are electrical appliances that combine manual switching functions with automatic protection against undervoltage, overload, and short-circuit faults. They can be used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. When serious overloads, short circuits, or undervoltage faults occur, they automatically disconnect the circuit, functioning similarly to a combination of a fuse switch and over/under-voltage relays. Furthermore, they generally do not require component replacement after interrupting fault currents and have gained widespread application.

Schneider Electric's common molded case circuit breakers include the NSX, CVS, EZD, and NSC series. For the Schneider Electric NSX series, 100/160/250 refers to its frame current, and F/N/H represents its breaking capacity, which is 36/50/70kA respectively.
