Three-pole fixed design with front terminals and a TMF release delivers compact protection in control panels. This combination reduces wiring errors and speeds up installation, since conductors can be brought in from the front and tested without removing interior components. It is well-suited for panel builders upgrading legacy gear or stocking standardized MCCBs for critical loads in manufacturing and process facilities. Electrical durability of 1500 cycles and mechanical durability of 8500 operations translate into longer service life in high-switching environments. Operators benefit from predictable performance during peak loads and automated sequences. The robust TMF release provides reliable tripping under overload and short-circuit events, helping prevent equipment damage and unplanned downtime in plant-wide protection schemes. Rated current of 70 A and a rated insulation voltage of 690 V position this MCCB for medium-power circuits in distribution boards. With a rated operational voltage of 550 V AC and 250 V DC, it supports diverse loads, while short-circuit ratings up to 50 kA (Ics) and 100 kA (Icu) at 240 V AC define strong fault-clearing capabilities for transformer-fed customers. Documentation and compliance are streamlined by the included wiring diagram FORMULA A1/A2, the Data Sheet 1SDC210032D0204, and the CE Declaration of Conformity. The RoHS and REACH declarations, plus TSCA compliance, support audits and regulatory reporting. Order code US/Canada AAN070TW and EAN 8015644006389 simplify procurement, while the 1-piece packaging aids stocking and shipping. Front-terminal connection and 3P TMF design offer straightforward installation in SACE Formula environments and enable easy retrofits in existing switchgear. The product is compatible with ABB's SACE Formula family and benefits from standard wiring diagrams and manuals, reducing training needs for installers. With compact dimensions (76.2 mm width, 130 mm height, 60 mm depth) and lightweight packaging, on-site handling is efficient.
