A circuit breaker is a device designed to prevent circuits from overloading and causing fires or damages. The 1140-G151-P7M1-0.05A circuit breaker is an example of such a device which is commonly used in residential, commercial and industrial applications.

The 1140-G151-P7M1-0.05A circuit breaker is designed to protect electrical circuits from overloads, short circuits and other potential hazards using a thermal-magnetic trip unit. It is a three-pole device with ratings of 600V AC and trip currents of 5A. This circuit breaker is UL 489 rated and carries UL, CSA and VDE certifications.

The working principle of 1140-A15-P7MI-O.O5A circuit breaker is based on the combination of two different mechanisms: thermal and magnetic. The thermal mechanism uses a bimetal strip that expands when heated to interrupt an electrical circuit. When the current is too high, the bimetal expands and triggers the tripping mechanism. The magnetic mechanism consists of a solenoid coil which acts like an electromagnet when powered by electric current. This electromagnet is connected to a plunger, so when the current becomes too high, the plunger moves and releases the operating latch that triggers the tripping mechanism.

The 1140-G151-P7M1-0.05A circuit breaker can be used in applications such as residential and commercial buildings, subpanels, motor control centers, and industrial transfer switches. These breakers can be used in both indoor and outdoor areas as they are designed to be robust and weather resistant. Additionally, they come with a wide range of accessories such as external trip indicators, switch positions, and shunt trips for various applications.

The 1140-G151-P7M1-0.05A circuit breaker is a reliable and effective solution for protecting electrical circuits from overloading and short circuiting. It features a thermal-magnetic trip unit that can quickly and accurately sense how much current is passing through the circuit and trip if the current is too high. It is also robust, weather resistant, and comes with a range of accessories for various applications.
