Feature: The SPC150120N8P delivers a 150 kAIC interrupt rating for 120 V single-phase systems, delivering robust surge capacity that clamps transients before they reach sensitive electronics. Business Impact: This level of protection reduces the risk of transformer saturations, contact wear, and PLC input faults, translating into fewer unplanned outages and lower maintenance costs. Application: Ideal for panel boards, servo drives, motors, and control relays in packaging lines and automation cells where large transients are common and downtime is costly. Feature: NEMA 4X enclosure construction delivers dependable environmental protection against dust, water spray, and corrosion in washdown and damp locations. Business Impact: Enables safe, code-compliant deployments in harsher environments without extra enclosure costs or retrofits. Application: Outdoor cabinets, factory floors near washdowns, and food/beverage lines where equipment must withstand aggressive environments. Feature: Integrated filtering suppresses high-frequency noise and reduces EMI/Q, preserving signal quality and device longevity. Business Impact: Improves sensor readings, stabilizes PLC timers, and reduces nuisance trips caused by transient noise on control loops. Application: CNC machines, robotic cells, and conveyor systems where precise timing and predictable control are essential. Feature: Alarm signaling and Form C relay offer immediate fault indication and remote control capability. Business Impact: Supports proactive maintenance, quick isolation of faults, and integration with plant-wide monitoring systems, boosting uptime and safety. Application: PLC inputs, SCADA dashboards, and energy management systems across manufacturing lines. Feature: External side mounting and a compact footprint streamline installation and future scalability. Business Impact: Speeds panel commissioning, minimizes required panel depth, and simplifies retrofits in existing machines, reducing installation labor and downtime. Application: New builds and upgrades across packaging, plastics, automation, and general manufacturing where reliable surge protection is a must.
