What is an Instantaneous Relay ?

Instantaneous Relay Definition

An instantaneous relay is defined as a relay that operates with no intentional delay when the current exceeds a set threshold.

No Intentional Delay

Instantaneous relays activate without any added delay, making them very fast in operation.

Inherent Delays

These relays still have minor delays due to electrical and mechanical factors, but they are not intentionally introduced.

Types of Instantaneous Relays

Examples include attracted armature relays, solenoid type relays, and balance beam relays.

Operation Mechanism

These relays rely on electromagnetic attraction to move a plunger or beam to close the relay contacts quickly.
