FAQs
Installation with external sidemount mounting is straightforward and designed to minimize field wiring complexity. Ensure the mounting surface supports NEMA 1 indoor use and that the distribution equipment provides the required clearance for side access. Follow the Eaton installation manual to configure the external disconnect and verify L-N, L-G, and L-L connections align with the 240V delta network. Proper grounding and labeling improve safety and serviceability.
The product is specified for 240V delta (4W+G) configurations and delivers up to 100 kAIC interrupt rating, allowing it to absorb high-energy transients common in delta networks. Its sidemount design keeps protection close to the protected loads, reducing path length for transient energy and improving response time. This translates to lower risk of equipment damage and extended component life.
Yes, the SPD100240H2M is UL 1449 listed, confirming compliance with recognized surge protection standards. It protects a broad range of loads including motor drives, control circuits, lighting, and distribution equipment in 240V delta systems. With a 100 kAIC interrupt rating and 150 L-N, 150 L-G, 150 N-G, 300 L-L operating voltages, it safeguards both sensitive electronics and heavy machinery.
Integration into existing panels is facilitated by the external side mounting and NEMA 1 enclosure, minimizing internal modifications. Maintenance considerations include periodic visual inspections for signs of wear, verification of disconnect integrity, and confirming continuous operation of the internal protection components. The 15-year warranty provides a long-term lifecycle advantage and supports budgeting for spare parts and service planning.
Expect operating voltages of 150 L-N, 150 L-G, 150 N-G, and 300 L-L, enabling coverage across varied circuits from lighting to heavy equipment. The 100 kAIC rating delivers robust transient energy handling, while the 240V delta configuration ensures balanced protection for 4W+G systems.
