Technical selection summary
| Listing / reference model | T7S 1200A UL489 3P/4P PR331/P LSIG |
|---|---|
| Product type | Moulded case circuit breaker |
| Manufacturer AC-frequency reference | 50–60 Hz for the Tmax T7 catalogue family; confirm the complete standard and trip-unit configuration |
| UL-family voltage reference | The UL catalogue rates the T7 1000/1200 A family at 600 V AC; IEC 690 V data must not be applied to a UL unit |
| Electronic trip-unit reference | The PR23x/P and PR33x/P electronic protection families provide configurable protection settings; thresholds, delays and available functions depend on the exact release. Confirm the fitted trip-unit code |
| T7S 1000/1200 A fault-current reference | ABB data sheet 1SXP210009D0201 lists T7S at 65 kA / 240 V AC, 50 kA / 480 V AC and 25 kA / 600 V AC, 50–60 Hz. Select the complete UL/CSA code and voltage-specific rating |
| Separate H/L version reference | For the same 1000/1200 A data-sheet family, T7H is 100/65/50 kA and T7L is 150/100/65 kA at 240/480/600 V AC respectively. Each column belongs to its own S/H/L version; IEC 1250/1600 A selections require their separate data |
ABB Tmax T7 UL489 family reference. Match the full T7 code, rated voltage, frame and installed trip unit. LI, LSI and LSIG functions depend on the exact trip-unit configuration. Do not apply IEC 1250/1600 A entries to a UL 1200 A selection. These catalogue references do not authenticate a supplied unit or establish every current approval.
Typical applications
- Low-voltage distribution protection with a matched UL configuration.
- Switchboard procurement with exact frame, trip unit and voltage-specific fault ratings.
