Why Choose the ABB T7V800 PR332/P-LSIRc 800A 4-Pole Circuit Breaker?
The ABB T7V800 PR332/P-LSIRc is a high-performance moulded case circuit breaker (MCCB) designed for dependable protection and switching in demanding low-voltage power distribution systems. As part of the proven ABB SACE Tmax T7 series, it combines an 800 A rated current with the advanced PR332/P electronic trip unit and residual-current protection.
The PR332/P-LSIRc electronic release provides long-time overload, short-time and instantaneous short-circuit protection together with residual-current protection. This comprehensive protection package helps safeguard conductors, equipment and installations against overloads, high fault currents and earth-leakage conditions while supporting adjustable protection coordination.
This version is a 4-pole fixed circuit breaker with front terminals and motor-operable configuration. The T7V performance level provides an ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC, making the breaker suitable for industrial switchboards and distribution systems with high prospective fault currents.

Advanced Circuit and Residual-Current Protection
Moulded case circuit breakers such as the ABB Tmax T7 protect low-voltage electrical installations against overloads and short circuits while providing reliable switching and isolation. Electronic trip technology enables protection thresholds to be adjusted to match installation requirements and support coordination between upstream and downstream protective devices.
The PR332/P-LSIRc release extends conventional overcurrent protection with integrated residual-current protection. This makes the T7V800 particularly suitable for installations where both high fault interruption capability and protection against earth-leakage currents are required.
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 residual-current protection.
- Installations with high prospective short-circuit currents.
