FAQs
For a safe, reliable install, mount the unit in a suitable location on a rigid panel or enclosure, ensure correct phase connection to the delta network, and wire per the manufacturer’s diagram. The NEMA 4 enclosure protects against moisture and dust, while the internal circuit breaker simplifies isolation during maintenance. Verify up-front rating compatibility with the delta configuration and maintain clear labeling for future servicing.
Yes. The device is RoHS compliant and UL 1449 listed, with CSA certification support. This combination ensures compliance with global safety and environmental standards, facilitating regulatory approvals and reducing risk during audits or multi-site deployments.
The SPM250240H3R provides up to 250 kA per phase protection, designed to clamp transient surges and divert energy away from protected equipment. This performance supports critical loads such as motors and drives in high-energy environments, helping minimize nuisance trips and equipment damage during transient events.
The unit carries a 15-year warranty from delivery, with a 20-year term available when registered on Eaton’s site. This extended coverage reduces total cost of ownership and provides long-term assurance for mission-critical protection in industrial facilities.
The internal circuit breaker enables quick disconnection for maintenance without external hardware, while the NEMA 4 enclosure protects against dust and moisture, enabling reliable operation in harsh outdoor or damp indoor spaces. Together, they simplify installation, enhance safety, and reduce field modification needs during commissioning.
