ICHYTI 2 pole 63a ac mcb Working principle

◉ MCB is a type of building electrical terminal protection appliance, mainly composed of operating mechanisms, contacts, protection devices (including overcurrent releases, thermal releases, and undervoltage releases), and arc extinguishing systems. The operating mechanism can be manually or electrically closed, and after closing, the free release mechanism locks the main contact. The overcurrent release and thermal release are connected in series with the main circuit, while the undervoltage release is connected in parallel with the power supply.

◉ When a short circuit or severe overload occurs in the circuit, the coil of the overcurrent release generates a magnetic field, causing the armature to absorb and operate the free release mechanism, thereby causing the main contact to open. When the circuit is overloaded, the thermal component of the thermal release heats up, causing the bimetallic sheet to bend and pushing the free release mechanism to operate. When the circuit is under voltage, the armature of the undervoltage release releases, causing the free release mechanism to operate.
