Bussmann TVSS-10 – Frequently Asked Questions
1) What system voltage is the Bussmann TVSS-10 surge suppressor rated for?
600 Vac. That covers typical 480V and 600V commercial and industrial distribution circuits where transient voltage clamping is required. On lower-voltage systems you would normally specify a device matched to that service instead, for example the Square D Surgelogic unit rated 208Y/120V 3-phase 4-wire.
2) Can the Bussmann TVSS-10 be used on a circuit with high available fault current?
Yes. The TVSS-10 carries a 200,000A RMS symmetrical interrupt rating, so it is usable where the available short circuit current at the equipment is high, as is common on large commercial and industrial service entrances. Confirm the rating against the fault current calculated for your equipment location.
3) Can an Eaton BRNSURGE10 be used instead of a Bussmann TVSS-10?
They are not interchangeable. The Bussmann TVSS-10 is a tubular surge protection limiter with a melamine tube body, nickel-plated brass endcaps, and printed circuit board tabs for direct board mounting into a surge protection assembly. The Eaton BRNSURGE10 is a two-pole 10kA surge protective device in the BR Series, built to mount into a load center as a breaker-style device. If you are protecting a panel at the breaker position, the BR Series device is the form factor that fits; the TVSS-10 is the component that goes inside a surge suppression circuit.
4) For three-phase 208Y/120V service entrance protection, is the Bussmann TVSS-10 the right choice?
No. The Bussmann TVSS-10 is rated 600 Vac as a single surge protection limiter element with a 200,000A RMS symmetrical interrupt rating and tubular end connections. For three-phase service protection, the Square D Surgelogic surge protective device is configured for 208Y/120V three-phase four-wire systems at 500kA, which matches a service entrance or distribution panel application. Use the Surgelogic unit for the panel and the TVSS-10 where a discrete limiter is called for in an assembly.
5) Will the TVSS-10 physically fit inside a crowded enclosure or on a populated board?
Its body measures 1.54 x 0.46 x 0.46 in, so it takes up very little room in a panel, enclosure, or PCB-mounted assembly. The PCB tabs let it sit flat against the board rather than needing separate mounting hardware.
6) What part number do I order for the Bussmann 600V tube-style surge suppressor?
Order by Bussmann MPN TVSS-10. That is the single model, so there is no finish, pole, or voltage option to select on it.
7) How does the Bussmann TVSS-10 differ from a Square D Surgelogic panel SPD?
Two different levels of protection. The Surgelogic EMD25 is a 500kA, 208Y/120V 3-phase 4-wire assembly that mounts to a panel and protects the whole distribution board. The TVSS-10 is a small 600 Vac suppression limiter with tubular ends and PCB tabs that sits inside an assembly or on a circuit board. If you are specifying service-entrance or branch-panel protection, the Surgelogic style is the right category; if you are replacing a suppression element in existing equipment, the TVSS-10 is.
8) Which of these surge devices goes in the panel and which goes on a circuit board?
The Bussmann TVSS-10 is the board-level part: it measures 1.54 x 0.46 x 0.46 in and uses printed circuit board tabs with tubular end x tubular end connections for direct mounting. The Eaton BRNSURGE10 and Eaton BRPSURGE are both BR-type surge protective devices built to install in a load center, and the Square D Surgelogic unit is a panel-mounted three-phase device. If a drawing calls for a surge limiter inside an assembly, that is the TVSS-10; if it calls for panel protection, it is one of the others.
9) Is the 10 in Bussmann TVSS-10 the same 10kA rating as the Eaton BRNSURGE10?
They describe different things. The 10 in the Bussmann TVSS-10 corresponds to its amp rating, consistent with the model designation, and the device carries a 600 Vac rating with a 200,000A RMS symmetrical interrupt rating. The 10kA in the Eaton BRNSURGE10 is the surge current rating of that two-pole BR Series panel device. Do not read the two numbers as equivalent when matching a spec.
10) What is the Bussmann TVSS-10 made of, and will it hold up in an industrial environment?
The body is a melamine tube with nickel-plated brass endcaps. Melamine is a hard thermoset insulating body, and the nickel plating on the brass caps resists corrosion at the contact surfaces, which matters in plant and switchgear environments where humidity and contaminants are a factor.
11) Where does a device like the Bussmann TVSS-10 typically get installed on a job?
It goes into transient voltage suppression circuitry: panelboards and power distribution equipment, printed circuit board assemblies that need surge protection, and industrial or commercial power systems. Electricians most often use it as the replaceable suppression element inside an existing surge protection assembly rather than as a standalone panel accessory.
