Rated Current (In): 25A
The circuit breaker is designed for a 25A current rating, making it suitable for moderate-sized electrical circuits. It effectively protects devices and wiring from overloads while ensuring the electrical system operates smoothly.
6kA Short-Circuit Breaking Capacity (Icn)
With a 6kA breaking capacity, the MCN325A can safely interrupt fault currents up to 6,000 Amps, preventing damage to the electrical system during fault conditions. This feature ensures that the breaker can handle high fault currents typically encountered in industrial and commercial setups.
C-Type Tripping Curve
The C-type tripping characteristic of the breaker means it can withstand brief surges in current (like those caused by motor startups) while providing reliable protection against sustained overloads and short circuits. It trips if the current exceeds 5 to 10 times the rated current (25A) for a short circuit.
Thermal and Magnetic Protection
Thermal Protection: The breaker offers thermal protection for overload situations. It trips if the current exceeds 1.13 to 1.45 times the rated current for a prolonged period, preventing overheating and potential damage to the wiring and connected devices.
Residential Installations:
Protects three-phase circuits supplying power to household appliances, HVAC systems, water heaters, and other electrical loads.
Commercial Installations:
Safeguards electrical systems in offices, retail spaces, restaurants, public buildings, and small commercial setups, providing reliable protection for lighting, air conditioning, and other equipment.
Industrial and Manufacturing Environments:
Ideal for motor circuits, machine control centers, conveyor systems, and industrial machinery, the breaker ensures the protection of valuable equipment against overloads and short circuits.
