Lochinvar L100290102 Fuse 6.3 Amps

Product Description

The LOCHINVAR L100290102 is a 6.3-amp fuse designed to protect electrical circuits within LOCHINVAR heating and hot water systems. This fuse serves as an overcurrent protection device, interrupting the circuit when current exceeds the rated threshold and preventing damage to sensitive control components. It is a direct-fit replacement part installed by licensed HVAC technicians and plumbers during routine service or after an overcurrent event. At 6.3 amps, it provides protection suited to low-voltage or control-circuit applications typical in commercial and residential boilers and water heaters.

This fuse is used in LOCHINVAR heating equipment where circuit protection is required at the control board or internal wiring harness level. It is appropriate for residential and light commercial installations where LOCHINVAR boilers or water heaters are in service. Technicians typically replace this part as part of a diagnostic procedure following a tripped or blown fuse condition, or as a precautionary measure during a control board service call.

Key Features

• Rated at 6.3 amps for control-circuit overcurrent protection
• Direct OEM replacement for LOCHINVAR heating and water heating equipment

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber familiar with LOCHINVAR equipment. Always shut down the unit and disconnect power before replacing any fuse or control component. Confirm the root cause of the overcurrent condition before installing a replacement fuse to prevent repeat failure. Verify the replacement fuse amp rating matches the original specification before installation.
