If the connected load exceeds this amount for too long, the breaker will trip to prevent overheating and potential fire hazards. It's suitable for high-power devices like large air conditioners, industrial sockets, or heavy appliances.
The "1P" or single-pole designation means the breaker is meant to protect one live (phase) wire. This is standard in single-phase electrical systems, typically found in homes and small businesses. It interrupts only the live line and is usually paired with a neutral conductor.
A C-type tripping curve means the breaker will trip when the current reaches 5 to 10 times the rated current (in this case, between 315A and 630A). This is great for circuits with moderate inrush currents — like electric motors, fans, and fluorescent lights — where a brief surge happens when switching on but shouldn't cause a trip.
The MCB can safely disconnect a short-circuit current up to 6,000 amps. This is known as its "breaking capacity." It's a safety feature that ensures the breaker won’t be damaged or cause fire during extreme fault conditions, making it suitable for residential and light commercial use.
This breaker is rated for 230 volts alternating current, which is the standard voltage for single-phase power in many countries including India. It's designed to be used in circuits operating at this voltage level.
FEATURES:
This MCB combines thermal and magnetic protection. Thermal protection reacts to slow overloads (like plugging in too many devices), while magnetic protection reacts instantly to short circuits (such as a direct fault between live and neutral).
The breaker is designed to easily snap into place on a DIN rail, which is the standard mounting system used in distribution boards and electrical panels. This makes it easy to install or replace.
It offers basic finger-safe protection at the terminals, meaning you won’t accidentally touch live parts. This rating is suitable for indoor panels that are enclosed or inaccessible to the public.
The breaker is built to last, with mechanical durability up to 20,000 operations (manual switching on/off), and electrical durability for about 10,000 fault-handling trips. So it’s reliable for years of use under normal conditions.
