Four-pole fixed front-terminal design simplifies wiring and reduces assembly errors, delivering clean panel density and reliable mechanical alignment. This configuration minimizes field wiring mistakes, speeds panel assembly, and enhances serviceability during maintenance. It is well suited for main distribution boards, motor control centers, and transformer feeders where space is tight and reliability matters. Thermomagnetic release (TMD) provides fast, selective tripping for overloads and short circuits, limiting fault energy and protecting downstream equipment. In practice, users see reduced nuisance trips and improved uptime in demanding production environments. This feature supports motor starters, conveyors, and processing lines where precise protection is essential. Rated at 32 A with 690 V AC and 750 V DC capabilities, the device balances protection with efficiency for mixed-load panels. The robust ratings reduce stocking variety and simplify design decisions for engineers. It pairs with MCCs, switchgear, and distribution boards in modern plant layouts. Ics up to 200 kA and Icu up to 200 kA under IEC conditions provide a wide fault-current margin. This ensures fast interruption without compromising system reliability, even in sites with high short-circuit potential. It supports transformer-fed feeders and large motor circuits common in heavy manufacturing. RoHS and REACH declarations, together with CE conformity and GL certification, streamline regulatory compliance and supplier auditing. Documentation supports environmental responsibility and data traceability across multinational projects. Front-terminal wiring and compatibility with the SACE Tmax T4 family simplify installation, retrofits, and future expansion. The fixed-front design minimizes rework and offers predictable mounting, while standard packaging and EAN support efficient logistics. This makes it a practical choice for panel builders and systems integrators. Physical footprint and weight provide predictable space planning for compact switching gear with 140 mm width, 205 mm height, 103.5 mm depth, and 3.05 kg weight.
