Industrial 305E-101-A-10-XX Electromechanical Timer

Industrial 305E-101-A-10-XX Electromechanical Timer is a Marsh Bellofram ATC 305E series motor‑driven analog reset timer designed for short, repeatable delays in 120 VAC control circuits. It operates from 120 VAC at 60 Hz and delivers a 6‑second timing interval in the 101 family, with timing controlled by a synchronous motor and an electrically operated clutch. The unit provides a load‑carrying contact rated around 10 A, making it suitable for switching common industrial loads in panel‑mounted control logic. Within the 305E family, configurations support either ON‑Delay or OFF‑Delay operation depending on model, allowing the timer to integrate into sequencing and interlock applications. This plug‑in timer features a compact, rugged construction for industrial environments and is used to introduce precise, short delays in automation circuits, such as relays, solenoids, or other line‑powered devices, where reliable timing and reset behavior are essential. The 101 variant focuses on a 0–6 second interval with analog reset capability, while other 305E models extend the available timing ranges, providing a flexible timing solution across multiple applications in control panels and automated equipment.
