An SPD is a protective device that guards electrical systems from transient surges. Its 300 kA per phase surge protection capacity provides robust defense for motors, drives, and panel boards, resulting in reduced equipment damage and lower incident-driven downtime in manufacturing environments. The NEMA 4X enclosure with an internal terminal block offers durable, weather-resistant installation and easier wiring, cutting commissioning time and minimizing field wiring errors on indoor and outdoor panels. This single-module Max series design saves panel space and simplifies wiring for 277/480 VAC 4W+G systems, improving compatibility with existing switchgear and facilitating quicker upgrades of aging protection schemes. The surge counter delivers real-time visibility into surge activity, supporting preventative maintenance planning and compliance documentation. RoHS compliance and established UL/CSA certifications help mitigate regulatory risk and support enterprise-wide safety programs, while the 15-year warranty (20 years with registration) lowers total cost of ownership for critical loads.
