Technical Parameters Parameter Specification Series / Product Type ABB AX Series Manual Motor Starter / Protector Order Code AX18-30-10 Poles 3-Pole (for three-phase motors) Utilization Category AC-3 (Squirrel cage motor: starting, switching off) Rated Operational Current (Ie) Up to 18 A (This is the maximum current-carrying capacity of the main contacts. The "18" in AX18 denotes this.) Rated Thermal Current (Ith) Adjustable Range: 0.10 - 18 A (The "30-10" likely refers to the specific adjustment dial range, e.g., 0.30 - 10 A for the thermal element. The exact sub-range must be confirmed from the label.) Thermal Overload Setting Continuously adjustable via a rotary dial within the specified sub-range (e.g., 0.3 to 10A). Short-Circuit Protection Magnetic instantaneous trip, typically set at 12 x Ith or a fixed value (e.g., ~200A for this frame size). Rated Operational Voltage (Ue) 690V AC Rated Insulation Voltage (Ui) 690V AC Control Voltage Not applicable - manually operated. Rated Short-Circuit Breaking Capacity (Icu/Ics) Typically 6 kA or 10 kA at 400V AC (specific value depends on certification). Ambient Temperature Compensation Yes, built into the bimetal mechanism. Trip Class Class 10 (The "10" in "30-10" often indicates this). This means it will trip within 10 seconds at 720% of the set current. Auxiliary Contacts None on the basic unit. Some models offer optional, add-on auxiliary contact blocks (e.g., 1NO+1NC) for signaling. Mounting Snap-on mounting for DIN Rail (35mm) or screw mounting. Connection Terminals Screw terminals suitable for solid and stranded conductors. Standards Compliance IEC/EN 60947-1, IEC/EN 60947-4-1, UL 508, CSA C22.2 No. 14. Degree of Protection (IP Rating) IP00 (component). Requires an enclosure for IP20 or higher. Ambient Temperature -25°C to +60°C (operation)
