FAQs
When retrofitting, verify the panel’s available space and ensure the 120/240 V split-phase supply matches the SPM120240S1T. Confirm the internal terminal breaker is compatible with your busbar arrangement and on-panel shutoff practices. Use proper torque on connections and follow Eaton’s installation sheet to minimize trip nuisance and maximize protection reliability in control panels.
The 120 kA per phase rating can absorb large transient surges typical in industrial environments, shielding sensitive control electronics, drives, and PLC inputs from damage. This reduces the likelihood of unexpected downtime, extends component life, and lowers maintenance costs by preventing surge-induced failures during grid disturbances or switching events.
Yes. The device is designed for 120/240 V split-phase systems and features a NEMA 4 enclosure with an internal terminal breaker, making it suitable for both indoor and outdoor installations where weather resistance and rugged protection are required.
The SPM120240S1T is UL 1449 and UL 1283 listed, CSA Std. C22.2 No. 8-M1986 certified, CSA Electrical Notice NO. 516 Ed. 1 compliant, and RoHS compliant. These certifications ensure regulatory alignment for electrical safety, performance, and environmental standards, reducing certification risk in audits and customer requirements.
Investing in the SPM120240S1T mitigates surge-related equipment damage, reducing unplanned downtime and extending the life of critical devices. The extended warranty (15 years, 20 years with registration) lowers long-term maintenance costs, while the RoHS compliance and rugged NEMA 4 enclosure support durable performance in challenging environments.
