What does relay protection time delay mean
The Time Delay is the intentional, adjustable time lag introduced between the relay picking up (current exceeding ) and the issuance of a trip signal to the circuit breaker (CB). Commonly used in HVAC systems and motor control, it enhances safety, prevents equipment damage, and ensures proper sequencing of electrical processes. Instead, it waits for a pre-determined amount of time before switching its contacts. The delay can be set anywhere from milliseconds to hours, depending on the relay design.
