High surge capability up to 160 kAIC provides robust protection against faults, reducing the risk of equipment damage and downtime, which translates to lower maintenance costs in panelboards and MCCs. The 277 V single-phase rating aligns with common industrial power distributions, delivering targeted protection where it matters most in motors and conveyors. A NEMA 4X enclosure ensures environmental resilience against dust, water spray, and washdown conditions, supporting reliability in harsh plant floors and outdoors. The Form C relay enables remote signaling and control integration, improving fault visibility and interlock capabilities for safer, automated shutdowns. External side mounting facilitates flexible installation alongside existing busbars and enclosures, simplifying retrofits and upgrades within SPC series protection schemes. A 10-year warranty underpins total cost of ownership, assuring long-term protection and planning certainty for maintenance budgets.
