Description
The Littelfuse KRDB424 Delay-On-Break relay is used in HVAC system applications and has dimensions of 2 x 2 inches. It has a microcontroller-based timing circuit that enables a time delay from 1 to 100 minutes at 120 VAC to control the equipment accurately. This relay is specifically useful in controlling the operations of the compressor and eliminating short cycling in HVAC systems, increasing energy conservation and product durability. It is shock and humidity-resistant, and the SPDT output contacts are isolated to handle different types of loads. The advantages are increased dependability, less stress on the parts, and increased safety in a variety of Tough conditions.
