Insulated Case Circuit Breaker vs. Ordinary Circuit Breaker: Functions and Differences
Main Function:
Protects circuits and equipment from overload, short circuit, and other faults.
The insulated case provides additional safety against arcing and electric shock, suitable for high voltage and high current applications.
Features:
Strong breaking capacity, capable of quickly cutting off fault currents and limiting peak short-circuit currents.
Equipped with operating mechanisms, trip units, arc extinguishing systems, and other components for safe and reliable circuit interruption.
Ordinary Circuit Breaker
Main Function:
Also protects circuits and equipment from overload, short circuit, and other faults.
Compared to insulated case circuit breakers, they are more commonly used in low voltage and small to medium current applications.
Features:
Basic protection functions such as overload and short circuit protection.
Easy to operate, usually controlled manually or remotely via electrical signals.
Difference and Connection
Difference:
Insulated Case Circuit Breaker is primarily used in high voltage and high current scenarios, offering stronger breaking capacity and enhanced safety features.
Ordinary circuit breakers are suited for low voltage and small to medium current applications, known for their ease of operation and relatively lower cost.
Connection:
Both are crucial for protecting circuits and equipment, providing similar protective functions.
In specific circumstances, insulated case circuit breakers can substitute ordinary circuit breakers, contingent upon specific application requirements.
