Special features
Basic
SPM250240S1R delivers 250 kA per phase transient energy handling for 120/240 V split-phase systems. This capability translates to higher protection margins for critical loads such as PLCs, drives, and sensors, reducing the risk of damage during voltage spikes and electrical storms on the factory floor. With a NEMA 4 enclosure and an internal circuit breaker, the unit is suited for damp or dusty environments and simplifies field wiring. The integrated breaker helps isolate faulted circuits without opening multiple panels, saving installation time and reducing panel space requirements. RoHS compliance and broad certifications—UL 1449, UL 1283, CSA—support global deployment and code compliance in regulated industries, easing supplier qualification. Max series single module design keeps footprint manageable, with dimensions of 9.3 in length, 17.5 in height, and 14.91 in width and a 50 lb weight. The compact form, plus the internal breaker, enables straightforward mounting and wiring in existing cabinets. Warranty covers 15 years from delivery, extending to 20 years with registration on Eaton’s SPD portal, lowering total cost of ownership for OEMs and maintenance teams.
