1SFL587102R1200

ABB 1SFL587102R1200 – AF305-40-00-12 is a heavy-duty 4-pole AF series power contactor intended for motor starting, isolation, bypass and high-current power-distribution applications in industrial electrical installations. It is fitted with four normally open main contacts (4NO) and no factory-mounted auxiliary contacts in the standard -00 configuration.

The AF305 contactor has an AC-3 operational current rating of 305 A at 380–440 V and is suitable for three-phase motors up to approximately 160 kW at 380–400 V, 415 V and 440 V. For AC-1 resistive or slightly inductive loads, ABB specifies a rated operational current of 500 A at 690 V and 40°C ambient temperature.
