The primary side of a circuit breaker refers to the side where the main electrical supply or incoming power is connected. Essentially, it is the input side of the breaker, through which electricity enters before being distributed to various circuits or loads. Understanding the primary side is important because it helps in the proper installation, maintenance, and troubleshooting of circuit breakers.

In most setups, circuit breakers have a clearly marked input (primary) and output (secondary) side. The primary side is usually connected to the main supply, which could be from a utility transformer or a generator, depending on the application. From here, the breaker protects the downstream circuits by automatically interrupting the flow of electricity in case of overloads, short circuits, or faults.

The primary side often carries a higher voltage or current level, so proper insulation, secure connections, and correct sizing of circuit breakers are crucial to ensure safety. Many industrial and residential breakers also have terminals specifically labeled for the primary input, making installation straightforward.

In addition, Lauritz Knudsen circuit breakers, like transformers or three-phase breakers, may have separate primary and secondary windings or connections, but the principle remains the same: the primary side receives power, and the breaker safeguards the downstream network.

The primary side of a circuit breaker is the incoming power side that feeds the device. Correct identification and connection of this side are essential for ensuring the breaker functions efficiently and protects the electrical system as intended.
