The Fluke 28II Ex Intrinsically Safe digital multimeter is designed to prevent the accidental detonation of explosive atmospheres.

Using the correct replacement fuse block is essential to the safety of that design. The Fluke 440 mA fuse assembly is specifically designed to be used in the 28II.

Used in the following Fluke Digital Multimeters

Fluke 28 II Ex Intrinsically Safe True RMS Digital Multimeter

The post Fluke 440 mA fuse assembly for Fluke 28 II Ex Intrinsically Safe Multimeter appeared first on rapid-tech.

This is a high-energy fuse is designed to keep the energy generated by an electrical short within the fuse enclosure. This protects the user from electric shock and burns. The Fluke 315 mA 1000 V fuse is designed to limit the amount of oxygen available for combustion and the length of time the energy is applied.

This 1000 V fuse is sand-filled to absorb the shock energy created by the current overload. The and will also help absorb the high temperatures (up to 10,000 °F) generated. The energy will melt the sand and turn it to glass, helping smother a potential fireball by cutting off the available oxygen, further protecting the user.

When an electrical short occurs while making a current measurement, the user relies upon the high-energy fuse in the test tool for protection. The Fluke 440 mA, 1000 V fuse is designed to keep the energy generated within the fuse enclosure, protecting the user from electric shock and burns.

This fuse limits the length of time energy is applied and the amount of oxygen available for combustion.

The Fluke 440 mA 1000 V high-energy fuse is sand-filled which helps absorb the shock energy created by the current overload. It also controls the potential high temperatures generated (up to 10,000 °F).

The energy created from an electrical short will melt the sand, turning it to glass. This helps smother a potential fireball by quickly cutting off the available oxygen, further protecting the user.

This high-energy fuse is designed to protect a user from electric shock and burns. It does this by keeping the energy generated by an electrical short within the fuse enclosure.

The fuse is built to limit the length of time the energy is applied and the amount of oxygen available for combustion.

The fuse is filled with sand to stop an electrical short. The sand will not only help absorb the shock energy created by the current overload, but also help with the high temperatures generated (up to 10,000 °F).

The energy will melt the sand and turn it to glass, helping smother a potential fireball by cutting off the available oxygen, further protecting the user.
