Description
The Mars 81138 is a 30-amp, 600-volt time delay fuse engineered to provide dependable overcurrent and short-circuit protection in HVAC and refrigeration electrical systems. Its time delay design allows temporary inrush currents — common during motor startups and compressor cycling — to pass without nuisance tripping, while still responding quickly to sustained overloads and fault conditions.
Key Features
- 30A amperage rating for robust circuit protection
- 600V voltage rating suitable for a wide range of HVAC applications
- Time delay action accommodates motor startup inrush currents
- Helps prevent nuisance tripping during normal equipment operation
- Designed for use in HVAC, refrigeration, and commercial electrical panels
- Compact fuse body fits standard fuse holders and disconnect blocks
Applications
- Air conditioning and refrigeration compressor circuits
- Fan motor and blower motor branch circuits
- Commercial and residential HVAC disconnect panels
- General-purpose motor branch circuit protection
Why Choose a Time Delay Fuse?
Time delay fuses are the preferred choice for motor-driven HVAC equipment because they tolerate the brief but high inrush current drawn when a motor starts, without sacrificing protection against genuine overloads or short circuits. This reduces unnecessary service calls and extends the life of your electrical components.
