1E11PT15.5 Application Field and Working Principle

The 1E11PT15.5 is a specialty fuse designed by the Midget Fuse Company for small electrical equipment within the aero, maritime and general industrial fields. It is especially designed for use in equipment used to control power distribution. In particular, this fuse is intended for specialized applications that require a high level of current switching capacity.

The 1E11PT15.5 fuse is a miniaturelimiting fuse designed to provide overcurrent protection and isolation. The fuse is rated for interrupting currents of up to 1,500 amp at 240 VAC RMS or DC. This fuse is capable of protecting against both normal circuit overloads and short-circuits without damaging equipment.

The 1E11PT15.5 fuse complies with UL 248-14 and CSA C22.2 No. 248.14 standards. The fuse features a 2.371 inch diameter body that fits removable panel mount adapters. It has a 250V AC interrupting rating which enables it to safety switches and controls.

Operation Principle

The working principle of the 1E11PT15.5 fuse is simple. When the current through the fuse exceeds the pre-set value, the fuse element will be heated due to the current passing through. As the fuse element heats up, it will expand and eventually reach a point where it will break down the connection between the fuse’s electrodes, preventing any further current passing through.

The 1E11PT15.5 fuse also features a built-in thermal trip mechanism. This feature allows the fuse to be reset once the current flowing through it has been decreased or reduced.

Applications

The 1E11PT15.5 fuse is designed for use in a variety of medium power applications. Some examples of the applications the fuse is designed for include:

• Switching and control of medium power circulation circuits
• Power distribution equipment found in office buildings and industrial sites
• Electrical automotive components, including speed regulators and wipers
• Safety and protective circuits for gas, air, and liquid lines
• Aviation, maritime and industrial-grade electric motors

Advantages

The 1E11PT15.5 fuse offers a number of advantages compared to other fuses. These include:

• The highest AC rating for a mini-limiting fuse in its class
• High switching capacity
• Meets all applicable UL and CSA standards
• Compact size
• Low temperature rise
• Easy installation and operation

Conclusion

The 1E11PT15.5 is a specialty fuse designed specifically for applications in power distribution equipment. The fuse meets all applicable UL and CSA standards and offers a high switching capacity while maintaining a compact size. This fuse is ideal for use in aviation, maritime, and industrial-grade equipment.
