FuseBox 100A Fused Switch with Type 2 SPD & 63A, 80A, 100A Fuses | SF0100T2

100A Fused Switch with Integrated Type 2 Surge Protection

The FuseBox SF0100T2 is a 100A 1P+N fused switch with integrated Type 2 Surge Protection Device (SPD), providing isolation, fuse protection and surge protection within one robust metal enclosure.

Supplied complete with 63A, 80A and 100A gG cylindrical fuses, the SF0100T2 gives installers the flexibility to select the appropriate fuse rating for the installation. FuseBox specifies a maximum load of 100A / AC21, with the unit incorporating a Type 2 SPD as standard.

The steel enclosure, generous cable capacity, integrated surge protection and padlock facility make this an excellent solution for appropriately designed domestic and commercial electrical distribution installations.

FuseBox's current documentation confirms that the SF0100T2 includes the Type 2 SPD plus all three 63A, 80A and 100A gG fuses.

Fused Switching up to 100A

The SF0100T2 combines a 100A rated switch with a dedicated fuse holder, allowing the outgoing supply to receive overcurrent protection using the appropriate supplied fuse.

FuseBox supplies three fuse ratings with the unit:

• 63A
• 80A
• 100A

All three are 22 x 58mm cylindrical gG fuses, with gG being a general-purpose fuse classification suitable for conductor protection.

This gives installers greater flexibility when configuring the unit according to the requirements of the installation.

Integrated Type 2 Surge Protection Device

Unlike the standard SF0100 fused switch, the SF0100T2 incorporates a Type 2 SPD.

The integrated surge protection device helps protect the electrical installation and connected equipment against transient overvoltages, providing surge protection alongside the unit's switching and fuse protection functions.

This combined design can provide a neat and convenient solution where a fused switch and Type 2 surge protection are required at the same point in the installation.

100A / AC21 Maximum Load

FuseBox specifies the SF0100T2 with a maximum load of 100A / AC21 and a 1P+N configuration.

The fuse rating should be selected according to the electrical installation requirements, with 63A, 80A and 100A options supplied with the unit.

Robust Steel Enclosure

The SF0100T2 is housed within a durable steel enclosure, providing a professional and robust solution for electrical distribution applications.

The enclosure measures 314mm high x 236mm wide x 88mm deep according to FuseBox's current installation leaflet.

Flexible Cable Entry

For convenient installation, the enclosure provides 1 x 20mm and 1 x 32mm knockout at both the top and bottom.

This gives installers flexibility when routing incoming and outgoing cables while helping maintain a neat installation. FuseBox recommends the use of appropriate glands to maintain the enclosure's protection and fire-containment properties.

Generous Terminal Capacity

Designed to accommodate substantial supply conductors, the SF0100T2 provides generous connection capacity.

The main switch and fuse holder both accept conductors up to 35mm², while the earth terminals accommodate up to 16mm². FuseBox specifies recommended tightening torques of 2.5Nm for the main switch, 4.0Nm for the fuse holder and 2.5Nm for the earth terminals.

Padlock Facility

The enclosure incorporates a padlock facility, providing an additional option for securing the switch where isolation procedures require it.
