Description
The MARS 33243 Thermal Time Delay Relay is a control component used to manage delayed switching of electrical circuits in heating and cooling equipment. It is applied in system configurations where staggered or timed activation is required to protect components and ensure proper startup sequencing. In HVAC systems this relay provide a controlled time delay before opening or closing a single-pole single-throw circuit based on thermal response. Installed within the control assembly, it supports motor protection, reduces inrush, and ensures coordinated timing between control signals and connected electrical loads.
