GE CK75CA300 / CK75CA311N 3-Pole Power Contactor

The GE CK75CA300, also known as CK75CA311N, is a heavy-duty, industrial-grade 3-pole magnetic contactor that can handle a lot of power switching and motor control. This unit is part of the famous GE C-2000 series. It can manage a thermal current of 250A and a rated operational current of 150A under AC-3 conditions.This contactor is built to last in tough conditions and can switch three-phase motors up to 75kW at 400V. Its modular design makes it easy to add extra contacts and protection devices, which makes it a key part of motor control centers (MCC) and industrial automation.

Technical Specifications

Key Features

• High Thermal Capacity: This device can handle a standard thermal current of 250A, therefore it will be stable while running all the time without overflowing.
• AC-3 Performance: It can handle 150A during heavy motor starting and stopping cycles because it was made for inductive loads.
• Modular Auxiliary System: It has one normally open (NO) and one normally closed (NC) auxiliary contact that makes it easy to connect to signaling or interlocking circuits.
• Better Arc Suppression: The new design of the contact chamber minimizes arcing, which considerably extends the life of the silver-alloy contacts.
• Global Compliance: It meets the standards of IEC 60947-4-1, UL, and CSA; therefore, it may be used to export industrial equipment to other countries.
