Magnetic Trip Unit for MCB Miniature Circuit Breaker (3058006)
1. The core of the magnetic release is an electromagnet (composed of a coil and an iron core): when the short-circuit current passes through the coil, a strong electromagnetic force is generated, which attracts the iron core to move, and then pushes the mechanical mechanism of the circuit breaker, so that the moving and static contacts are quickly separated, and the circuit is cut off in a very short time (usually milliseconds), avoiding the continuous action of the short-circuit current, which may cause the line to overheat, the equipment to burn out, and even cause a fire. 2. Whenever a continuous overcurrent flows through the miniature circuit breaker (MCB), the bimetallic strip will heat up and bend and deform. The deformation of the bimetallic strip releases the mechanical latch. Since this mechanical latch is connected to the operating mechanism, it disconnects the miniature circuit breaker contacts, and the miniature circuit breaker (MCB) is disconnected, thereby cutting off the current in the circuit. To restart the current, the miniature circuit breaker (MCB) must be opened manually. This mechanism prevents faults caused by overcurrent or overload and short circuit.
During continuous testing in an 80°C high-temperature chamber, conventional trip units exhibited a 15% performance deviation due to magnetic attenuation. Our CeramMag™ ceramic composite magnet technology maintains an operating accuracy of ±2% within a temperature range of -55°C to 125°C, making it the preferred solution for applications such as metallurgy and deep-sea equipment.
