FAQs
This model uses fixed front terminals designed for front-access wiring, simplifying panel wiring and reducing installation time. Ensure proper torque per ABB guidelines, provide adequate clearance for 186 mm width and 205 mm height, and follow standard ABB mounting procedures to preserve protective coordination and maintain clear labeling in switchgear enclosures.
Key specs include 4 poles, rated current 320 A, rated operational voltage 690 V AC, rated insulation voltage 1000 V, and rated impulse withstand voltage 8 kV. It offers high short-circuit capabilities with Ics and Icu values suitable for industrial feeders, plus mechanical and electrical durability ratings appropriate for demanding environments.
Yes. As part of the SACE Tmax T family with E-LSIG release, it is designed for transformer and switchgear protection, offering reliable tripping and coordination. The 4P configuration with front terminals supports compact protection schemes in medium to large distribution panels commonly used in industrial plants.
The device carries EC CE conformity with a Declaration of Conformity and complies with IEC standards. It also provides RoHS compliance and CMRT reporting, supporting regulatory and sustainability requirements for procurement and supplier audits.
The MCCB’s durable construction (4P design, front terminals, robust release) and alignment with Tmax T parts reduce spare-parts variety and maintenance complexity. The high endurance ratings (electrical and mechanical) translate to lower downtime, predictable lifecycle costs, and easier stocking of compatible components across similar protection schemes.
