Mersen D02 gG Fuse Link 25A 400VAC/250VDC

The Mersen D02 gG fuse link is a precision-engineered electrical protection device designed to safeguard circuits with a 25A rating. This component is specifically built to handle both alternating current up to 400VAC and direct current up to 250VDC, making it a versatile solution for diverse electrical environments. By interrupting the circuit during overcurrent or short-circuit events, it prevents damage to sensitive equipment and reduces the risk of electrical fires in both industrial and residential power distribution systems.

Advantages

This fuse link offers exceptional reliability and consistent performance under standard operating conditions. Its gG characteristic ensures full-range protection, meaning it can safely clear both low-level overloads and high-level short-circuit currents. The robust construction of the D02 size fuse guarantees long-term durability and operational stability, providing peace of mind for critical electrical infrastructure. Its standardized design allows for seamless integration into existing fuse bases and distribution panels, ensuring quick and efficient maintenance.

Suitable for

• Residential electrical distribution boards
• Industrial control panels and automation systems
• Protection of lighting and heating circuits
• General power distribution networks

When it may not be suitable

This fuse is not intended for use in circuits exceeding its 25A current rating, as this could lead to nuisance tripping or failure to protect the circuit correctly. It is also not suitable for high-voltage applications beyond the specified 400VAC or 250VDC limits.

Key specifications

• Rated current: 25A
• Rated voltage: 400VAC / 250VDC
• Fuse size: D02
• Characteristic: gG (full-range protection)

How to use

The fuse link should be installed into a compatible D02 fuse base or holder by a qualified professional. Ensure that the power supply is disconnected before attempting to insert or replace the fuse to prevent accidental contact with live parts. Once the fuse is securely seated in the base, the circuit can be re-energized. If the fuse blows, it must be replaced with an identical unit to maintain the safety integrity of the electrical system.

What to consider before purchase

• Verify that the 25A rating matches your circuit requirements
• Ensure compatibility with D02 size fuse bases
• Check that the voltage rating meets your system specifications

Usage recommendations

Always replace a blown fuse with one of the exact same type and rating. Never attempt to bypass or repair a fuse, as this compromises the safety of the entire electrical installation.
