Mersen 25A Rail Mount Fuse Holder for 31 mm, 2P-Pole, 400V ac

This rail-mount fuse holder provides a secure method for housing 31 mm fuses on a DIN35 mm rail in electrical installations. It is intended for use where a compact, two-pole protective device is required and where environmental vibration and a broad temperature range are considerations. The body is MADE from thermoplastic and it is designed for alternating current systems up to 400 V.

• 25 A rating delivers consistent current protection for circuits
• 400 V AC capability supports medium-voltage distribution systems
• Thermoplastic case reduces weight while insulating live parts
• Anti-vibration design maintains contact integrity in motion
• Operates from -40°C to 70°C for varied ambient conditions

• Suitable for rail-mounted distribution panels in industrial sites
• Ideal for rolling-stock electrical assemblies requiring vibration resistance
• Used with 31 mm fuses in control and protection circuits
• Appropriate for modular installations on DIN35 mm rails

It provides two poles, enabling simultaneous switching or protection of two conductors in a Compact footprint.

It is compliant with IEC 60947-3 and IEC 60269-2 and meets RoHS and REACH requirements.

The thermoplastic enclosure offers electrical insulation while accommodating continuous operation up to 70°C maximum.

Marine certificates are pending, so it should be specified accordingly until certification is issued.
