Why Choose the ABB T7V800 PR332/P-LSIG 800A 4-Pole Circuit Breaker?
The ABB T7V800 PR332/P-LSIG is a high-performance moulded case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage power distribution systems. As part of the proven ABB SACE Tmax T7 series, this breaker combines an 800 A rated current with the advanced PR332/P electronic trip unit and comprehensive LSIG protection.
The PR332/P-LSIG release provides long-time, short-time, instantaneous and earth-fault protection, allowing the breaker to protect circuits against overloads, short circuits and earth faults. Its adjustable protection settings support effective coordination and selectivity within industrial and commercial electrical distribution systems.
This model has a 4-pole fixed configuration with front terminals and a stored-energy operating mechanism. The T7V breaking-capacity version provides an ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC, making it suitable for installations with high prospective fault currents.

Advanced Protection for Power Distribution Systems
Moulded case circuit breakers such as the ABB Tmax T7 protect low-voltage electrical systems against potentially damaging overload and short-circuit conditions while providing reliable circuit switching and isolation. Electronic protection enables operating thresholds to be adjusted to suit the characteristics of the installation and improve coordination between protective devices.
The PR332/P-LSIG trip unit adds earth-fault protection to long-time, short-time and instantaneous protection functions. Combined with the T7V frame's high interruption capability, this provides comprehensive protection for demanding industrial power-distribution networks and switchboards.
Typical Applications
- Industrial low-voltage switchboards.
- Main and sub-main power distribution systems.
- Manufacturing and process facilities.
- Commercial and infrastructure electrical installations.
- Distribution systems requiring earth-fault protection.
- Installations with high prospective short-circuit currents.
