FAQs
Follow Eaton's installation guidelines: verify compatibility with switchgear remote displays, mount the SPD using internal integration, wire per 4W+G configuration, and connect the Form C relay contact if needed. After mounting, test the audible alarm, surge counter, and EMI/RFI filter to confirm proper operation before commissioning.
An interrupt rating of 100 kA per phase indicates each phase can safely absorb a single surge event up to 100 kA without failing. Paired with a 200 kA short-circuit rating, this supports robust protection against high-energy transients typical in industrial environments and helps prevent downstream equipment damage.
Yes. The SPD100600Y3B is rated for 347/600 V wye (4W+G) systems and 50/60 Hz operation, making it well-suited for motor starters, switchgear, and process equipment in heavy industry where transient protection and reliability are critical.
The SPD100600Y3B is UL 1449 Listed, signifying compliance with recognized safety standards for surge protection devices. This certification supports safer operation, regulatory alignment, and quality assurance for mission-critical electrical protection in industrial facilities.
The built-in surge counter with rest button simplifies maintenance planning and fault tracking, while the 15-year warranty reduces long-term risk. By limiting downtime from transient events and improving control signal integrity, facilities typically see lower maintenance costs and higher equipment availability over the system lifetime.
