Product details

200 A soft starter with ATEX — motor starting in hazardous zones

The 3RW5076-2AB04 is a hybrid soft starter rated 200 A minimum operating current, covering motor loads from 200 A up to the device's full rating within a 200-480 V supply range. ATEX, UKEX, and IECEx certifications qualify this unit for installation in explosive atmospheres — a requirement for chemical, oil/gas, and grain handling lines where standard soft starters cannot go. Trip Class is configurable as CLASS 10A, 10E (preset), or 20E per IEC 60947-4-2, letting you match the overload protection to the motor start profile — 10A for short starts, 20E for longer acceleration times on high-inertia loads. Fieldbus options include PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET, so it drops into most control networks without a gateway.

Mounting and panel fit — screw-fix, 282x160x230 mm

Mounting is screw-fix only — no DIN-rail clip, so plan for a dedicated backplate or sub-panel. Dimensions are 282 mm deep, 160 mm wide, 230 mm high. The mounting position allows vertical surface with ±90° rotation and ±22.5° tilt front-to-back, giving some flexibility for tight enclosures but not a free orientation. Clearance requirements: 100 mm upwards, 10 mm forwards, 0 mm backwards, 75 mm downwards, 5 mm at the side — factor these into the panel layout for airflow and cable entry.

No stock-holding claim — quoted per order. UL, CSA, and CE markings are on file, covering North American and European regulatory acceptance without additional certification steps.

Frequently asked questions

Where can I buy 3RW5076-2AB04 and how do I get a price?

No stock-holding claim is made here.

What ATEX and UKEX certifications does 3RW5076-2AB04 carry?

ATEX, UKEX, and IECEx are all listed as 'Yes', meaning the unit is certified for use in explosive atmospheres per those standards. This is a key differentiator from standard soft starters.
