Bussmann HHT – Frequently Asked Questions
1) Is the Littelfuse 155400 an equivalent swap for the Bussmann HHT fuseholder?
No. The Bussmann HHT is a fuseholder intended for mounting inside panelboards, switchboards, and industrial control cabinets, where the fuse sits at a fixed, accessible point in the equipment. The Littelfuse 155400 is an in-line fuseholder from the 155 series, built to hold an ATO blade fuse spliced into a wire run rather than mounted to a panel. Different mounting method and different fuse body, so one does not drop into the other's place.
2) What is the Bussmann HHT and what part number do I order it by?
The HHT is a Bussmann fuseholder, a component that retains a fuse and connects it into a circuit. It is ordered under the manufacturer part number HHT, which is also how panel builders and maintenance teams cross-reference it for replacement.
3) For a control panel build, does the Bussmann HHT or a 155 series in-line holder make more sense?
For an industrial control panel assembly, the Bussmann HHT fuseholder is the one specified for that work, since it is built to mount inside the cabinet and keep the fuse reachable for routine inspection and replacement. The Littelfuse 155400 is an in-line ATO holder in the 155 series, which carries the fuse in the harness instead of on the panel, so it is typically used in wiring runs rather than as a panel-mounted overcurrent point.
4) Can I order the Bussmann HHT to hold an ATO blade fuse?
The ATO blade fuse format is what the Littelfuse 155400 in-line holder is built around. The Bussmann HHT is ordered as a single model, HHT, and is a panel and equipment mounted fuseholder within the Bussmann circuit protection line, so confirm the fuse body you are protecting with before pairing it. If the circuit calls specifically for an ATO blade fuse in a wire run, the 155 series in-line holder is the matching part.
5) Is the Bussmann HHT suitable for a retrofit, or only new panel builds?
Both. The HHT is used for new construction and retrofit electrical work, as well as routine fuse replacement in existing panels, so it serves equally as a repair part and as a component in a new control panel assembly.
6) Can fuses be changed in an HHT holder without pulling the holder out of the panel?
The HHT is built for accessible fuse inspection and replacement in place, which is the point of using a holder rather than hard-mounted fuse clips: maintenance crews can check and swap the fuse during a service call instead of rebuilding the connection.
