Description
The Littelfuse JLLS020 Fast-Acting Class T Power Fuse 20A, 600V is an electrical component in the HVAC systems to protect high-current circuits against short circuits and overloads. It can be installed in furnace, air handler, or rooftop unit control panels and is an interrupter that is activated in seconds and limits current when the safe current values are surpassed to prevent damage to transformers, motors and other delicate parts. This is because of its fast-acting nature. This is used in the system as a secure element that keeps the HVAC appliance in continuous and secure operation.
