Ma-line MA-ECNR25 Time Delay Fuse 250V 25A 10 Pack

Product Description

The MA-LINE MA-ECNR25 is a time delay fuse rated at 250 volts and 25 amps, sold in a 10-pack. Time delay fuses are designed to handle temporary inrush currents without nuisance tripping, making them a standard choice for motor loads, HVAC compressors, and other equipment that draws elevated current at startup. The time delay characteristic allows the circuit to survive brief overcurrent events while still providing reliable short-circuit protection. Licensed electricians and HVAC technicians routinely stock this style of fuse for service calls and panel work.

This fuse is suited for use in residential and light commercial applications where a 250-volt, 25-amp time delay fuse is specified. Common install scenarios include disconnect boxes, load centers, and equipment service panels on HVAC systems, refrigeration units, and motor-driven equipment. The 10-pack format makes it practical for technicians who replace fuses frequently and want to keep spares on hand in the service vehicle or shop.

Key Features

• 250-volt rating suitable for single-phase residential and light commercial circuits
• 25-amp ampacity with time delay characteristic for motor and compressor loads
• Time delay design reduces nuisance trips caused by startup inrush current
• Sold as a 10-pack for efficient restocking and field inventory
• Standard fuse format compatible with common fuse holders and disconnect blocks

Compatibility

Designed as an OEM-style replacement time delay fuse for use in 250-volt fuse holders, disconnect switches, and equipment panels requiring a 25-amp time delay fuse.

Installation Notes

Fuse replacement should be performed by a qualified electrician or licensed HVAC technician. Always de-energize and verify the circuit is dead using a calibrated meter before removing or installing fuses. Follow applicable NEC requirements for fuse sizing and disconnect access. Never replace a fuse with a higher ampacity rating than the circuit or equipment manufacturer specifies.
