Why Choose the Mersen T300696 Industrial Fuse?
The Mersen T300696 is an industrial electrical fuse designed to provide dependable overcurrent and short-circuit protection within compatible power, control and automation equipment. Manufactured by Mersen, this component is intended for electrical installations where reliable fault interruption is essential for protecting valuable equipment and maintaining system availability.
When electrical current exceeds the fuse element's specified operating limits, the T300696 opens the affected circuit automatically. This action helps restrict the thermal, electrical and mechanical energy generated during a fault, reducing the risk of damage to conductors, switching devices, control components and surrounding electrical assemblies.
The Mersen T300696 is suitable for industrial maintenance, repair and OEM replacement applications where this exact manufacturer reference has been specified. Before installation, its rated current, rated voltage, utilisation category, breaking capacity, dimensions and terminal arrangement should be verified against the original component or approved equipment documentation.

Reliable Protection for Industrial Electrical Systems
Overcurrents and short circuits can expose industrial equipment to excessive heat, electrical stress and mechanical forces. A correctly selected fuse responds by opening the affected circuit and limiting the amount of fault energy that reaches downstream components.
Correct fuse selection is essential for safe and dependable operation. A replacement component must match the required current rating, voltage rating, breaking capacity, operating characteristic, physical dimensions and connection arrangement. The T300696 should only be installed where this exact reference or a formally approved equivalent has been specified.
Typical Applications
- Industrial electrical control panels.
- Power distribution and conversion equipment.
- Motor control and automation systems.
- Production machinery and processing equipment.
- OEM electrical assemblies.
- Replacement of an existing Mersen T300696 fuse.
