FAQs
To install, verify the panel cutout matches the product net width of 101.6 mm, height of 130 mm, and depth of 60 mm. Use the front-terminal terminals for wiring, torque to the manufacturer's specifications, and ensure the device is mounted in the correct orientation. Confirm TMF release operation and test under no-load conditions before commissioning.
Key ratings include 90 A rated current, 690 V rated insulation voltage, 550 V AC / 250 V DC rated operational voltage, and a 6 kV rated impulse withstand voltage. Ics values depend on voltage tier (up to 50 kA at 240 V AC, 18 kA at 380 V AC, down to 2.5–5 kA at higher DC/AC variants).
Yes. The 4P moulded case design with TMF release, high Ics/Icu ratings, and front-terminal access make it suitable for transformer protection and generator accessory panels. Ensure the specific voltage and current levels match your transformer or generator protection scheme, and reference the wiring diagram FORMULA A1-A2 for correct wiring practices.
The device carries IEC standards, CE conformity, RoHS compliance, and CMRT/TSCA declarations. This simplifies cross-border procurement, supports regulatory audits, and reduces compliance risk in global supply chains. Documentation like the EAN, order code AAN090TW-4, and DoC streamline purchasing, stocking, and asset tagging in engineering and procurement systems.
Expect reduced downtime due to front-terminal wiring and a TMF release that provides reliable tripping under fault conditions. Mechanical durability (8500 cycles) and electrical durability (1500 cycles) support longer service intervals, lowering maintenance frequency. The compact footprint and high current-capacity enable denser panel designs, improving space utilization and overall return on investment.
