The 02391.25MXP series fuses from Bussmann Cooper have a variety of applications, including automotive, commercial, marine and industrial uses. They are particularly used where quick reaction to a fault current is essential, such as on power protection systems.

The 02391.25MXP fuses are designed to protect equipment from circuit overloads and short-circuits, which can occur due to incorrect wiring or mechanical failure. When an overload or short circuit occurs, the 02391.25MXP fuse will open, breaking the circuit and isolating the power. In order to provide protection against high levels of current, the 02391.25MXP has a time-lag construction that delays the reaction time of the fuse.

The 02391.25MXP fuse has an industrial-grade construction that can include a body made of either metal or plastic, with metal end-caps that contain the terminal clips. The fuse uses a copper alloy element to provide the current heating needed to open the fuse. This element is ignited by an internal lead that helps to create an electric arc when the fuse opens.

The 02391.25MXP is designed with a slow-response curve, meaning it has a greater tolerance for short-term overloads. For example, if an appliance is started up, the initial inrush of current may trigger an overload, but the 02391.25MXP has the capacity to limit this current inrush and so avoid a nuisance trip. This slow-response feature ensures that the 02391.25MXP is well suited for protecting power sensitive controllers and automation systems that are typically used in industrial environments.

The 02391.25MXP fuses are also designed with a reverse-current feature. This feature prevents current from flowing in the opposite direction, which can occur in systems with power-factor correction. This helps to ensure the integrity and reliability of the circuit. In addition, the 02391.25MXP is designed for low power loss, which helps to save energy and reduce operating costs.

The 02391.25MXP series is tested and certified for use by the International Electrotechnical Commission, ensuring that it meets all relevant safety standards in its application field. In addition, the 02391.25MXP fuses are UL listed, meaning that they are also recognized by Underwriters Laboratories Inc.
