The NEXE 3P 63A MCB is rated with a 6kA breaking capacity, meaning it can safely interrupt fault currents up to 6,000 Amps without causing damage to the electrical system or the MCB itself. This is critical for ensuring the protection of your circuits during high fault conditions.
This MCB is a 3-pole circuit breaker, designed for use in three-phase AC systems. It provides protection for all three phases, ensuring that the electrical system remains safe even when dealing with complex multi-phase loads.
Overload Protection: Protects circuits from excessive current due to extended overloads.
Short Circuit Protection: Instantly trips to disconnect the circuit in the event of a short circuit, preventing damage to cables and equipment.
FEATURES:
It features a Type C characteristic, making it ideal for inductive loads such as motors and transformers. This characteristic allows it to tolerate short-term inrush currents without tripping, making it well-suited for industrial and commercial applications.
The MCB is designed to fit into a standard DIN rail (4 modules), making it easy to install in electrical panels and switchboards, saving space while providing reliable protection.
The MCB is designed to operate in a wide ambient temperature range of -25°C to +70°C, making it suitable for use in both cold and hot environments.
The NEXE 3P MCB is rated IP20, meaning it is protected against solid objects larger than 12mm (such as fingers or tools), making it safe for use in environments where human contact is possible.
