FAQs
The AX300-30-11-81 is a three-pole block contactor featuring 3 main NO contacts and 1 NO + 1 NC auxiliary contact. It uses main circuit bars for connections and has IP40 auxiliary terminals. Ensure supply voltage is within 690 V insulation rating, and use 24 V control coil with 50/60 Hz to match your PLC or control logic. Adequate space and ventilation minimize derating at higher ambient temperatures.
Rated Operational Current AC-3 at 415 V/55°C is 305 A, at 440 V/55°C 305 A, at 500 V/55°C 290 A, at 690 V/55°C 290 A, and at 380/400 V/55°C 305 A, with similar values at 220/230/240 V. At higher ambient temperatures the Ie values decrease: 55°C yields lower current capability than 40°C. For condensation and startup surges, refer to the 8 x Ie breaking capacity and 10 x Ie making capacity ratings.
Yes, the AX300-30-11-81 carries CE and UL certifications, withIEC/EN compliance for AC-3 contactors and RoHS/Reach declarations. It complies with WEEE B2B categorization and is listed for motor protection and control. An optional CCC declaration and CQC certificate indicate broader regional approvals. The device also features IP40 protection for auxiliary terminals and a 690 V insulation rating.
With a mechanical durability rated at 5 million cycles and a per-pole power loss of 19 W, the AX300-30-11-81 offers long service life with predictable thermal performance. Plan for periodic inspection of contacts and coil health, and ensure cooling is adequate in high-load cabinets to prevent derating. Replacement timing aligns with observed contact wear and insulation integrity in demanding environments.
The combination of high AC-3 current ratings, low power loss per pole, and robust electrical endurance reduces downtime and maintenance costs while supporting higher motor starting reliability. Universal coil voltage and wide insulation enable faster modernization with fewer parts, lowering spare part variety. Overall, expect improved line uptime and reduced energy waste in high-demand applications like conveyors, pumps, and extrusion lines.
