Specifications: Type: Molded Case Circuit Breaker (MCCB) Number of Poles: 4P (4 poles) – Suitable for four-wire systems (3-phase + neutral) Current Rating: 320A Frame Size: 400M (denotes the frame size and protection characteristics for higher current systems) Rated Voltage: Typically 415V (for three-phase systems) Rated Frequency: 50/60 Hz Tripping Characteristics: Thermal-Magnetic Protection: Provides thermal protection for overload conditions and magnetic protection for short circuits. Adjustable Thermal Settings: Thermal protection can be adjusted to provide tailored overload protection depending on the specific application and load conditions. Magnetic Trip: Instantaneous disconnection when a short circuit occurs, minimizing the risk of damage to electrical components and reducing downtime. Breaking Capacity: Typically 36 kA at 415V (maximum fault current the breaker can safely interrupt) Protection Features: Overload Protection: Disconnects the circuit if the current exceeds the rated value for a prolonged period, safeguarding the circuit and connected equipment from overheating. Short-Circuit Protection: Disconnects the circuit instantly when a short circuit is detected, preventing further damage and protecting critical equipment. Manual Reset: The breaker can be manually reset after it trips due to an overload or short circuit, once the fault is cleared and it is safe to reconnect the circuit.
