Fuse Holders and Systems

NH fuse-bases are available for delivery in single-pole and three-pole designs and can be closely mounted in parallel rows. Each three-pole base is upplied with two phase-partition walls. NH fuse-links plugon covers which clip onto the contact springs can also be supplied for these bases.
Plastic fuse-bases sizes 00 to 3 have a single-part plastic base while size 4 has a metal baseplate with 2 ceramic bases.
The stable silver-plated contact springs are made of electrolytic copper and formed from one piece. Separate springing is provided by highly resilient captive steel springs, making the contact invulnerable to high thermal stress. Size 4 NH fuse-bases are designed for size 4 fuse-links with 8 mm contact blades.
A microswitch (250VAC/10A, terminal size 6.3x0.8mm) can be used with NH fuse-links with striker, it operates when fuse melts or where there is no fuse-link.
Indirect touch protection fuse bases: no microswitch possible.

Rated impulse withstand voltage Uimp: 6kV / 8kV (sizes 00 / 0-4)

Fuse bases for HV fuse link for motor protection with diameter 45mm and lengths 192, 292, and 442mm.
The indicating device enables electrical actuating of the opening mechanism for a circuit or triggering of an indicator during the melting of a fuse equipped with a trip-indicator.
This very robust and original device means freedom for any mechanical system and offers the advantage of being able to incorporate a microswitch unit or units according to the equipment configuration.

Vibration withstand:
These semiconductor AC/DC ferrule fuse holders are tested with sine vibrations carried out at ambient, scanning each of the 3 main axes.
Spectrom: 1st segment (2 to 16 Hz) constant displacement x = 5 mm peak.
2nd segment (16 to 250 Hz) constant acceleration γ = 5 g peak.
Exponential scanning speed: 1 octave per minute.
Duration: 2 hours per axis
