Wöhner 31274 AMBUS Panel DIN rail-mounted 3P/N fuse holder for 10 × 38 mm cylindrical fuse links, rated at 32 A and 690 V AC with an integrated neutral on the left-hand side.
£25.86
The Wöhner 31274 is a professional DIN rail-mounted fuse holder for 10 × 38 mm cylindrical fuse links, designed for three-phase electrical circuits requiring an integrated neutral connection. Its 3P/N configuration combines three fused poles with a neutral positioned on the left-hand side, helping panel builders create compact and organised protection assemblies.
Rated at 32 A and 690 V AC, the Wöhner 31274 is suitable for industrial control panels, electrical distribution boards, machine-building applications and factory automation systems. The holder accepts IEC cylindrical fuse links and supports gG fuse-link operating classes for dependable general-purpose cable and circuit protection.
The compact 54 mm-wide design mounts directly onto a standard mounting rail and incorporates cage-clamp terminals with a conductor capacity from 1.5 to 10 mm². An integrated label holder, IP20 protection and halogen-free construction make the Wöhner 31274 a practical and reliable choice for professional electrical installations.
The Wöhner 31274 enables three 10 × 38 mm fuse links to be installed alongside an integrated neutral connection within a compact 54 mm assembly. This configuration is particularly suitable for three-phase systems where the phase conductors require individual fuse protection and a dedicated neutral terminal is needed within the same device.
Its mounting-rail design supports fast installation in control cabinets, whilst the cage-clamp terminals provide secure conductor connections. The broad clamping range accommodates common industrial conductor sizes, helping simplify panel design and component selection.
The fuse holder is approved for gG cylindrical fuse links and can provide a conditional short-circuit rating of up to 100 kA when installed with the specified fuse ratings and system voltages. Aluminium conductors must not be connected to this product.
