Eaton MDL1-1/4 Time-delay Fuse 1.25A 250V Small Dim

Product Description

The EATON MDL1-1/4 is a small-dimension, time-delay fuse rated for 250 volts and 1.25 amps. MDL-series fuses are designed for low-amperage motor and appliance protection circuits where a brief inrush current must be tolerated without nuisance blowing. The small dimension form factor fits compact fuse holders and blocks commonly found in control panels, HVAC equipment, and light commercial electrical enclosures. Licensed electricians and HVAC technicians install this type of fuse during routine maintenance, troubleshooting, or control board replacement service.

This fuse is suited for residential and light commercial applications where a 250-volt, sub-2-amp overcurrent protection device is required in a small-dimension holder. Typical install scenarios include low-voltage transformer secondary protection, control circuit branch protection in furnaces, air handlers, and packaged units, and general appliance service panels requiring MDL-style fusing.

Key Features

• Time-delay design tolerates motor inrush current without nuisance blowing
• Small dimension body fits compact MDL-style fuse holders and blocks
• 1.25 amp rating for low-amperage control and appliance circuits
• 250 volt rating suitable for standard single-phase branch circuits

Compatibility

Designed as a direct replacement for MDL-series small-dimension fuse holders rated for 250 volts and up to 1.25 amps in residential and light commercial electrical and HVAC control applications.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with applicable NEC requirements. Always de-energize the circuit and verify zero voltage with a meter before removing or installing the fuse. Confirm the fuse holder is rated for the MDL small-dimension body before inserting. Never substitute a fuse with a higher amperage rating to work around a repeated overcurrent condition.
