High current capacity and front-terminal design enables compact, fault-tolerant installation with streamlined wiring and reduced panel depth, improving overall system reliability and ease of service in heavy industrial environments. This translates to faster commissioning and lower labor costs during panel upgrades in manufacturing lines and data centers. The fixed four-pole architecture provides robust phase protection, enabling precise coordination in power distribution, transformers, and motor control centers. The LSIG PR331/P release enhances operator safety with stored-energy isolation, reducing risk during maintenance and facilitating safer lockout/tagout procedures. With 690 V AC operation and 8 kV impulse withstand, the MCCB supports demanding drive and machine protection scenarios while maintaining stable trip performance across temperature and vibration. RoHS, REACH, CMRT, and CE declarations ensure regulatory compliance and supply-chain transparency for global projects, minimizing regulatory risk and enabling smoother audits. The Tmax T7 family compatibility simplifies retrofits and spare-part sourcing, delivering lower lifecycle costs and predictable maintenance planning for OEMs and end-users alike.

FAQs
Install the 4P MCCB in a compliant panel with fixed front terminals, ensuring correct clearance and access for wiring. Tighten terminations to manufacturer torque specifications, verify polarity, and use appropriate conduit entries. Confirm the PR331/P LSIG release is accessible for safe operation and follow local IEC and CE requirements during commissioning.
Rated current In is 1250 A, rated insulation voltage Ui is 1000 V, and rated impulse withstand voltage Uimp is 8 kV. It operates up to 690 V AC, with 4 poles and a PR331/P LSIG release for reliable protection and selective coordination in heavy-duty power circuits.
Yes. The 690 V AC rating, 4P configuration, and high breaking capacities (Icu/Ics) support motor protection, transformer feed, and distribution panel protection in challenging industrial environments. The front-terminal design also simplifies integration into existing gear and shortens retrofit timelines.
The device carries CE conformity, IEC standards, RoHS compliance, CMRT reporting, and TSCA declarations. These ensure regulatory alignment for global deployments and reduce audit risk, while supporting sustainable and compliant supply chains.
LSIG spring-loaded release with stored-energy mechanism enables safer, faster operation and reduced maintenance effort.
