Eaton 3TA100G6K Eaton Contactors and Overload Relays

Razz Middle East supplies the contactor and relay reference catalogued in this group under Eaton. Contactors and their associated overload relays form the switching element of a motor starter — the part that makes and breaks the motor circuit on a control command and protects the motor against sustained overload. It is sourced to order and delivered duty-paid, normally within three weeks.

About Eaton Contactors and Overload Relays

A contactor is an electrically operated switch: a coil pulls in a moving armature that closes the main power poles and any auxiliary contacts, and drops out when the coil is de-energised. Three main poles switch the motor, auxiliary contacts feed the control circuit for interlocking and status, and the coil voltage is a separate ordering choice from the power rating. Sizing is by utilisation category rather than by current alone — AC-3 for squirrel-cage motor switching, AC-1 for resistive and general loads, AC-4 for inching and plugging duty — so the same contactor carries different ratings in each category. A thermal or electronic overload relay mounts directly beneath the contactor, senses the motor current in all three phases and trips the coil circuit on sustained overload or phase loss, with an adjustable current dial that is set to the motor's nameplate full-load current. Accessories that clip on separately include additional auxiliary contact blocks, mechanical interlocks for reversing pairs, surge suppressors across the coil, and timer modules for star-delta starting.

Eaton Contactors and Overload Relays in Saudi Arabia

Contactors and overload relays are the most numerous power-switching items in Saudi plant, sitting in every motor control centre and pump panel. That covers utility and process pumps in the Jubail and Yanbu petrochemical complexes, seawater intake and high-pressure pumps in desalination trains, conveyors, crushers and fans in cement plants and at Ma'aden mining sites, compressors and chillers in building services, and packaging and processing lines in food and beverage plants. Mains are 380/400 V three phase at 60 Hz, and the 60 Hz figure matters twice: coil ratings are declared for a frequency, and the motor full-load current used to set the overload dial comes from the 60 Hz nameplate figure, not the 50 Hz one on a European motor list. High ambient temperature in unconditioned switchrooms is the other local factor, since both contactor and overload relay derate as panel temperature rises. Devices supplied into the Kingdom are subject to SASO conformity requirements.

Ordering and lead time

Order by the exact reference on the device label and tell us the coil voltage separately, because the same contactor frame is catalogued in many coil ratings and the reference on an old maintenance record often omits it. State the motor rating in kilowatts and its full-load current, the utilisation category the starter works in, the number and type of auxiliary contacts, and whether an overload relay, mechanical interlock or surge suppressor is fitted. If the contactor is a replacement in an existing panel, the mounting pitch, terminal arrangement and depth behind the door constrain the choice more than the electrical rating does, so send a photograph of the installation. Supplied on order and delivered duty-paid, normally three weeks from confirmation.
