Description
A 150Amp circuit breaker like the CB5-150A is a protective electrical device designed to interrupt current flow in a circuit when it exceeds 150 amps, preventing overloads, short circuits, or damage to wiring and equipment. It’s commonly used in automotive, marine, RV, or heavy-duty vehicle applications, such as buses and trucks, where high-amperage DC systems (typically 12V to 48V) need reliable protection for accessories like winches, inverters, audio systems, or auxiliary power circuits.
