Mersen SHR – Frequently Asked Questions

1) What voltage and amperage is the Mersen SHR bayonet fuse holder rated for?
The Mersen SHR is rated 300 VAC and takes fuses in the 0 to 15 A range. That covers standard fluorescent ballast and lighting circuit loads. It's a single-pole holder, so you get one fuse per ballast or branch, not a two-pole assembly.
2) What size wire does the SHR fuse holder come with, and do I need to add leads?
Leads are already on it. The SHR ships with tin-plated insulated copper wire leads, 6 inches of 18 AWG, so you splice straight into the fixture or panel wiring with wire nuts or crimps. Nothing extra to order for the connection itself, though the fuse is separate.
3) Is the Mersen SHR fuse holder UL Listed or UL Recognized?
UL Recognized. That's a component recognition, meaning it's intended to be installed inside a larger assembly such as a lighting fixture or a control panel rather than used as a standalone listed device. Specify it as a component of the panel or fixture build, not as field-installed standalone equipment.
4) Can an ABB ReliaGear Pro-Stock panelboard be used in place of a Mersen SHR fuse holder?
No - they do different jobs. The Mersen SHR is a single-pole fuse holder rated 300 VAC with a 0-15 A ampere range, mounted to a panel by an integral clip and wired in line with a fluorescent lighting fixture or ballast to protect that one circuit. The ABB ReliaGear Pro-Stock is a distribution panelboard that houses and feeds multiple branch circuits. If your drawing calls for individual ballast fuse protection inside a lighting fixture or control panel, the SHR is the device; the panelboard is the enclosure upstream that distributes power to those circuits, and you would typically have both on the same job rather than one instead of the other.
5) How does the SHR mount, and can I install it in a lighting control panel?
It's a panel-mount holder with an integral mounting clip, so it drops into a panel wall or fixture channel and secures without separate hardware. That's the intended use: commercial and industrial lighting control panels, ballast circuits, and general electrical control panels.
6) Do I need a tool to change the fuse in a Mersen SHR holder?
No. The bayonet terminal design lets you push and twist the fuse carrier out by hand, so a maintenance tech can swap a blown fuse on a lighting circuit without a screwdriver or a fuse puller. That's the main reason it gets specified for retrofit and service work on fluorescent fixtures.
7) Does the Mersen SHR come with a fuse?
The SHR is the holder only. You order the fuse separately, sized within the 0 to 15 A range at 300 VAC. What ships with the holder are the copper alloy contacts, the mounting clip, and the 6 inch, 18 AWG insulated leads.
8) For a service upgrade that needs a 400A three-phase main lug, is the Mersen SHR the right part?
No. The Mersen SHR is a 300 VAC, 0-15 A single-pole bayonet fuse holder with tin-plated insulated copper leads in a 6 inch of 18 inch wiring range - it is a component-level device for fusing an individual lighting or ballast circuit. For a 400 A three-phase main lug service, the ABB MeterMod III 400A Three-Phase Main Lug Panelboard is the class of equipment that applies. The SHR can still appear downstream inside lighting control panels fed from that gear.
9) What is the SHR body and contact material, and will it hold up to ballast heat?
Body is thermoplastic and the contacts are copper alloy. The thermoplastic housing is what lets it sit in a fluorescent fixture or ballast compartment, and the copper alloy contact surface is what keeps the fuse interface conducting cleanly over repeated fuse changes.
