Masterpact UR is designed to protect electrical systems with outstanding performance in terms of short circuit current limitation and fault detection speed. It contributes to safety and performance wherever high short-circuit current is involved.
The worldwide benchmark for high current circuit breakers for ultra-rapid protection
The Masterpact UR is a low voltage power breaker (based on the Thomson effect technology) with an ultra-rapid opening system on very high short-circuit levels. Its breaking performance makes it possible to limit the short-circuit current and the prospective energy, and consequently protect the electrical installation against the electrodynamic and thermal effects of short-circuit.
It is a key component in very high-power installations equipped with several sources connected in parallel, where the short-circuit current can reach very high levels and where continuity of service is a must. These power breakers provide outstanding performance in terms of speed of tripping, suitable for bus bar coupling onboard merchant vessels and off-shore platforms, and for loop networks in industry, cement plants, petrochemical industry, etc.
The range comes with a wide choice of standardized accessories. Its universal design allows most accessories to be used across the entire line. Masterpact UR provides peace of mind in terms of choice, installation, and operation.
Built from Schneider Electric’s highly reliable standard air circuit breaker, Masterpact UR was developed to allow much higher installed power with a LV design (no MV needed). It contributes to the reliability and continuity of service wherever high short-circuit current is involved, thanks to:
Integrated monitoring for energy efficiency
