Relay-based circuit protection employs a fundamental set of principles designed to safeguard electrical systems from damage caused by fault conditions. These relays function as intelligent switching devices, monitoring current levels and rapidly interrupting the circuit whenever a threshold is exceeded. This timely action prevents malfunctions that could result in loss of functionality, equipment degradation, or even fire hazards.

Key principles underlying relay-based protection include:

• Current Detection: Relays are equipped with sensing elements that continuously monitor the current flowing through the circuit.
• {Trip Point Setting|Threshold Determination|: A critical threshold known as the trip point is set to trigger the relay's operation when current exceeds this predetermined value.
• Rapid Response: Upon detection of an overcurrent, relays must respond swiftly to interrupt the circuit and prevent further damage.
• {Selective Coordination|Circuit Isolation|: In complex systems with multiple circuits, relays are often designed to coordinate their operation, ensuring that only the affected circuits are isolated.
