Bussmann TPHCS TPH Series High-Current Switch, 250A-800A

The Bussmann TPHCS TPH Series High-Current Switch is engineered by Eaton Bussmann as a Metric-configured high-current switch built for demanding DC power distribution work. This TPH series switch is available in 250A and 800A amp ratings, giving electrical professionals flexibility to match the switch to the load requirements of a given installation. Rated 80 Vdc, the switch terminates with a 1-1/4 In male quick-connect terminal for streamlined field wiring and carries a 100 kA short-circuit current rating (SCCR) for robust fault-current withstand in high-current circuits. As part of the widely specified Eaton Bussmann TPH series, this high-current switch is intended for professional electrical installations where dependable DC switching performance is required.

Key Features

  • Amp Rating: Available in 250A and 800A ratings, covering a broad range of high-current switching applications within the TPH series.
  • Voltage Rating: Rated 80 Vdc, suited to demanding DC power switching duty.
  • Quick-Connect Terminal: 1-1/4 In male quick-connect terminal simplifies installation and reduces field wiring time compared to bolted lug connections.
  • Metric Configuration: Metric-configured design for compatibility within the Eaton Bussmann TPH series lineup of high-current switches.
  • Short-Circuit Current Rating: 100 kA SCCR supports robust fault protection and helps maintain system coordination in high-current circuits.
  • TPH Series Design: Part of the Eaton Bussmann TPH series of high-current switches, built for heavy-duty industrial and commercial electrical systems.
  • High-Current Switching: Purpose-built as a high-current switch rather than a general-purpose disconnect, supporting sustained high-amperage DC loads.

Bussmann TPHCS250-M – Frequently Asked Questions

1) What amp ratings does the Bussmann TPHCS high-current switch come in?
Two: 250A and 800A. Order the 250 amp version as TPHCS250-M and the 800 amp as TPHCS800-M. There is no intermediate rating in between, so size to the actual continuous load of the circuit and pick the one above it.
2) How do the cables land on the Bussmann TPHCS switch, lugs or quick-connect?
Quick-connect. The TPHCS terminates with a 1-1/4 inch male quick-connect terminal rather than a bolted lug, so your cable ends need matching 1-1/4 inch female quick-connect terminals. If your existing feeders are lugged and bolted, plan on re-terminating.
3) What is the short-circuit current rating on the Bussmann TPH series switch?
100 kA SCCR. That matters when you are documenting the assembly's rating: the switch itself will not be the limiting component in most industrial DC panels, so the available fault current at the point of installation still has to be verified against the whole assembly.
4) Is the TPHCS a service disconnect or a load switch?
It is built as a high-current switch for sustained high-amperage DC loads, not as a general-purpose disconnect. Use it inside power distribution, switchgear, and motor control or power conversion assemblies where the switching duty is the point. If you need a listed service disconnecting means, specify a device sold for that role.
5) What does the -M suffix on TPHCS250-M mean?
It denotes the Metric configuration of the TPH switch. Both orderable versions, TPHCS250-M and TPHCS800-M, are the Metric build, so if your drawing calls out a non-metric TPH configuration, that is a different part number.
6) Will an 80 Vdc rated switch work on a 48 volt DC battery system?
Yes. 80 Vdc is the maximum rating, so nominal 48 V and 24 V DC systems sit inside it. Check the system's maximum charging or open-circuit voltage, not just the nominal, and keep it at or under 80 Vdc.
