Mechanical thermostat EM series

electromechanicalSPDTpanel-mount

Overview
The EM series comprises panel-mounted thermostats available as temperature controllers (TR), monitors (TW), limiters (TB), safety monitors (STW) and safety limiters (STB). The STB version moves the monitored system to a safe state in case of malfunction. Devices operate mechanically/electro‑mechanically and can function without auxiliary power where specified.

Highlights

• Self-monitoring capability (e.g. on pressure drop)
• Operation without auxiliary energy (mechanical/electro-mechanical)
• Multiple single-pole snap-action switch combinations (1–4 poles)
