Why Choose the ABB T7L 1000 PR332/P LSIG 1000A Circuit Breaker?
The ABB 1SDA062815R1, designated T7L 1000 PR332/P LSIG In=1000A 4p F F, is a high-performance four-pole moulded-case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage power distribution systems. As part of the proven ABB Tmax T7 series, it combines a rated current of 1000 A with the advanced PR332/P LSIG electronic trip unit for comprehensive protection of high-current electrical installations.
The T7L version delivers high short-circuit interruption performance, with a rated ultimate short-circuit breaking capacity of 120 kA at 380–415 V AC. Its PR332/P LSIG electronic trip unit provides long-time, short-time, instantaneous and earth-fault protection, allowing protection characteristics to be adjusted for effective coordination and selectivity within complex distribution networks.
With its four-pole configuration, fixed installation and front terminals, the 1SDA062815R1 is particularly suitable for three-phase systems where switching and protection of the neutral conductor are required. The breaker supports a rated operational voltage of up to 690 V AC and is designed for installation in industrial switchboards, power distribution centres and major commercial or infrastructure electrical systems.

Advanced Four-Pole Protection for Power Distribution
Moulded-case circuit breakers such as the ABB Tmax T7 protect low-voltage electrical networks against overloads, short circuits and earth faults. The T7L 1000 combines a high 1000 A current rating with substantial short-circuit interruption capability, making it suitable for main distribution circuits and installations supplied by high-capacity transformers or other sources with significant prospective fault currents.
The PR332/P LSIG electronic trip unit provides adjustable protection characteristics for long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault conditions. Combined with the four-pole construction and configurable neutral protection, this enables effective protection coordination across sophisticated three-phase and neutral distribution systems.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power distribution systems.
- Manufacturing and process plants.
- Commercial buildings and infrastructure installations.
- Transformer secondary and feeder protection.
- Three-phase and neutral distribution networks.
- High fault-level electrical distribution systems.
