Feature to benefit mapping drives tangible outcomes. The 30A amperage rating paired with a horsepower range of 5 to 30 HP enables safe isolation of moderate loads, reducing system downtime during maintenance and enabling flexible motor control in industrial plants. This translates to faster fault isolation and improved productivity on the shop floor, especially in hazardous environments where quick, reliable isolation matters. The non-fused design minimizes arc flash risk and simplifies maintenance routines, lowering spare parts inventory and speeding up replacements while maintaining compliance with NEC/CEC requirements. Copper-free aluminum reduces weight and material costs while improving corrosion resistance, which is crucial for outdoor or damp locations and contributes to reduced installation labor and long-term maintenance expenses. An external epoxy powder coat finish adds rugged durability and color-coded safety signaling, supporting safer field operations and fewer misoperations in complex panels. The broad voltage range of 240-600 VAC / 250 VDC accommodates multiple motor and control configurations, enabling engineers to standardize components across diverse lines and reduce stocking complexity. Enclosure with switch construction and UL/NEMA-rated features provide proven protection against dust, water, and corrosion while offering reliable operation in demanding environments. Compatibility with the EID series simplifies scalability, allowing seamless upgrades or expansions without wholesale rework, and supports standard mounting practices for easier retrofits and serviceability.

FAQs
The EIDA3030 S752 is designed for Hazardous/Classified Locations with NEC/CEC compliance and UL listings. It features a switch-equipped enclosure suitable for Class I Zone 2 and related classifications. For installation, mount using standard practices for explosionproof disconnects, ensure enclosure integrity, and follow the installation instructions in the IF1532 sheet to confirm proper wiring and torque specifications.
Key specs include a 30A amperage rating, a horsepower range of 5 HP to 30 HP, non-fused operation, copper-free aluminum construction, and a voltage range of 240-600 VAC / 250 VDC. The unit is equipped with a switch and is rated for outdoor or harsh environments due to its external epoxy powder coat finish and rugged enclosure.
Yes. The EIDA3030 S752 is explicitly rated for Hazardous/Classified Locations, including Class I Zone 2 and related classifications. This makes it appropriate for chemical and petrochemical processing facilities, oil and gas operations, and other environments where explosive atmospheres require certified isolation devices.
The disconnect switch complies with NEC/CEC standards and is listed for hazardous locations (UL). NEMA ratings include 9, 4X, 7, 3R, 4, and 3, reflecting robust protection against environmental hazards. This combination supports safe operation, regulatory compliance, and easier inspection in regulated facilities.
Maintenance benefits come from a corrosion-resistant copper-free aluminum enclosure with an external epoxy powder coat, reducing repainting and corrosion-related downtime. The non-fused design reduces contact wear and simplifies replacements, contributing to lower spare parts costs. Over time, the reliability and compliance benefits translate into lower total cost of ownership and improved production uptime.
