FAQs
Plan for external side mounting on compatible panelboards, ensuring proper clearance for the audible alarm and Form C relay wiring. Verify windowed access for status indicators, and confirm UL 1449 compliance and NEMA 4X suitability for outdoor or harsh environments.
The 160 kAIC rating means the device can safely interrupt high-energy surge events, protecting connected equipment from damaging transient voltages and reducing the likelihood of catastrophic failures in motors, drives, and control relays.
Yes. The unit is designed for 277 V single-phase systems and supports external side mounting, facilitating seamless integration into existing control cabinets and field installations without extensive rewiring.
The SPC160277N5P is UL 1449 listed and housed in a NEMA 4X enclosure, which matters for compliance and reliability in harsh environments, outdoor locations, and applications requiring durable protection against dust and water ingress.
By reducing surge-related equipment damage and downtime, the SPD lowers maintenance costs and extends asset life. The audible alarm and relay facilitate proactive fault signaling, enabling quicker response and less revenue-impacting interruptions in production lines.
