Front-terminal, four-pole design simplifies wiring and reduces installation time, lowering field labor costs while improving fault clearance speed in switchgear assemblies. In practice, Tmax T5 devices mount in compact panels without additional adapters, enhancing serviceability in multi-bay racks. High current and voltage ratings—IN 400 A, Ui 1000 V, Uimp 8 kV, Ue 690 V AC / 750 V DC—enable protection for transformers, MCCs, and distribution networks with wide operating ranges, reducing the risk of miscoordination during faults. The unit delivers a rated short-circuit capacity up to 200 kA and a 5 kA short-time withstand, translating to robust protection for critical loads and greater system availability. Durability is built in with 20000 mechanical cycles and 7000 electrical cycles, supporting longer service life and lower maintenance costs. The device meets CE, RoHS, REACH, CMRT and TSCA declarations, supporting global compliance and streamlined procurement. Front-terminal mounting also improves wiring clarity and reduces commissioning time in field installations, while compatibility with Tmax T5 applications ensures predictable performance in new builds and retrofit projects.
