The DIVERSITECH fh1 is an in-line fuse holder designed to protect control circuits carrying up to 30 amps on both AC and DC systems. Each unit features a rigid plastic protective covering that shields the fuse from mechanical damage and incidental contact. Sold in a pack of 10, this fuse holder is a practical stock item for HVAC technicians, electricians, and plumbers who routinely fuse low-voltage and line-voltage control circuits during installation or service work. UL Listed construction confirms the unit meets recognized safety standards for electrical components.
The fh1 fuse holder is suited for residential and light commercial applications where control circuit protection is required. Common install scenarios include HVAC control wiring, transformer secondary circuits, condensate pump circuits, and similar low-current branch circuits. The pack-of-10 format supports service vehicles and shop stock, giving technicians multiple holders on hand for a range of jobs.
Designed as an OEM-style in-line fuse holder suitable for AC and DC control circuits up to 30 amps across residential and light commercial electrical and HVAC applications.
Installation should be performed by a qualified electrician or licensed HVAC technician in accordance with applicable NEC requirements. De-energize the circuit and verify zero voltage before installing or replacing the fuse holder. Ensure the fuse rating inserted into the holder does not exceed the circuit conductor ampacity or the 30-amp holder rating. Secure all wire connections firmly before restoring power.
