FAQs
The CHNSURGECS is designed as a plug-on module for Type CH panels, enabling fast retrofits without rewiring your existing bus bar. To install, power down the panel, remove the panel cover, and align the unit with the Type CH slot before firmly snapping it into place. Verify L-N and L-L connections, then reassemble and test. Its compatibility with Eaton Type CH breakers ensures cohesive protection and simplifies ongoing maintenance while preserving panel density and wiring organization.
CHNSURGECS delivers 50/60 Hz operation with a 10 kAIC interrupt rating, 3 kA nominal discharge current, and an 18 kA surge current capability. The device provides L-N and L-L protection with a measured limiting voltage of 600 V. These ratings translate to rapid transient control, reduced insulation stress on downstream equipment, and enhanced uptime for sensitive automation components across standard industrial networks.
Yes. CHNSURGECS supports 50/60 Hz operation and protections for L-N and L-L circuits, with a maximum operating voltage of 150 V L-N and 300 V L-L. This makes it well-suited for control panels, MCCs, and machine cabinets operating in 120/240 V networks and in 208/230 V systems common to industrial facilities, providing reliable surge protection where downtime is costly.
CHNSURGECS carries UL 1449 and cUL certifications, signaling compliance with recognized safety standards for surge protective devices. This helps simplify procurement for regulated facilities, supports adherence to electrical safety programs, and provides auditable documentation for regulatory inspections, ensuring that installed protection meets established performance criteria.
Installing CHNSURGECS delivers measurable business value by reducing surge-induced equipment wear, minimizing unplanned downtime, and extending the life of critical components like PLCs and drives. Its plug-on design speeds maintenance-driven replacements, while the robust 18 kA surge rating and UL/cUL certifications provide confidence that protection remains effective across various load profiles.
