FAQs
The SPM120240H1T is designed for straightforward installation with an internal terminal breaker and a NEMA 4 enclosure. Begin by verifying system voltage (240 delta 4W+G), mount the unit in a compliant enclosure, connect phase leads per Eaton's wiring diagram, and secure all terminations. This approach minimizes startup time and ensures reliable protection for drives and controllers from day one.
Key specs include 120 kA per phase surge capability and a 240 delta (4W+G) voltage rating. This combination delivers robust transient suppression across phase A, B, and C with a high-leg configuration, making it suitable for demanding industrial loads. These ratings translate to improved equipment protection and reduced risk of nuisance tripping during spikes.
Yes. The device is specified for 240 delta with a 4W+G configuration, which accommodates high-leg delta systems. It provides phase-wise protection and simplifies integration with motors, drives, and control cabinets commonly found in manufacturing environments, helping avoid costly surge events.
The SPM120240H1T carries RoHS compliance and certifications including UL 1449, UL 1283, CSA standards (CSA Std. C22.2 No. 8-M1986 and CSA Electrical Notice NO. 516 Edition 1). These credentials support global procurement, safety compliance, and installation in regulated facilities.
It carries a 15-year warranty from delivery, extendable to 20 years when registered on Eaton's site. This extended coverage lowers lifecycle costs by reducing replacement frequency and maintenance uncertainty, delivering predictable ROI for critical assets like drives and control systems.
