Amperite 115C3 Delay Relay is a vintage vacuum‑tube style thermal time‑delay relay from Amperite Co., part of the 115C series and designed for 115 V operation with an eight‑pin octal base. It provides a fixed 3‑second delay before the contacts change state and is rated to switch up to 3 A, making it suitable for timing and sequencing tasks in older industrial controls and instrumentation. Some listings identify this unit as new‑old‑stock (NOS), reflecting its status as a legacy component ideal for restoration projects or retro equipment that require a precise short delay.
