High energy surge protection is essential in modern electrical systems. Feature: 100 kA per phase surge rating and 200 kAIC short-circuit rating deliver robust defense against transient events. Business impact: reduces risk of equipment damage, downtime, and costly replacements. Application: ideal for panelboards in manufacturing lines and distribution panels where voltage spikes threaten uptime. Nominal discharge current of 20 kA complements the high surge rating, filtering routine impulsive events without nuisance operations. Business impact: preserves sensitive electronics in PLCs, HMIs, and drives, extending component life and improving power quality metrics. Application: suitable for panelboards serving automation racks and machine centers in automotive, packaging, and food & beverage facilities. 12 7/220 V Wye (4W+G) voltage rating with 50/60 Hz compatibility ensures compatibility with a wide range of equipment. Business impact: simplifies specification and reduces design time for new installations. Application: used with panelboards (PRL-C) and downstream circuits requiring reliable line-to-neutral and line-to-ground protection. Built-in features including internal mounting, EMI/RFI filtering (up to 50 dB from 10 kHz to 100 MHz), audible alarm with silence button, and a Form C relay contact. Business impact: enhances fault visibility, improves compliance with electrical safety procedures, and enables remote signaling and monitoring. Application: supports control panels in factories and data centers seeking enhanced EMI/RFI suppression and quick fault responses. Surge counter with rest button provides a clear service history and quick reset. Business impact: enables traceability for maintenance and lifecycle planning, reducing unplanned outages. Application: beneficial for facilities managers tracking surge events in manufacturing floors, logistics hubs, and critical power infrastructure.
