Special features
Standard with surge counter
High surge capability with 320 kA per phase and 600 Delta (3W+G) architecture translates to durable protection for critical loads in manufacturing lines and process control systems. This feature reduces equipment damage, minimizes unplanned downtime, and lowers maintenance costs, enabling higher overall equipment effectiveness (OEE) and safer operations. The two-module MAX series design provides modular redundancy and easier serviceability, helping technicians swap or inspect modules without a full panel shutdown in complex installations such as packaging lines or robotic cells. A built-in surge counter offers event logging for compliance audits and preventive maintenance planning, while the NEMA 4X enclosure with an internal circuit breaker delivers reliable weather resistance and immediate fault isolation in harsh plant environments. RoHS compliance ensures leverage across global supply chains, supporting sustainability goals and regulatory alignment. The unit’s 15-year warranty (20 years with online registration) offers predictable total cost of ownership and long-term support for capital projects. Compatibility with standard electrical distribution layouts and straightforward wiring paths further reduces installation time and labor costs, making it suitable for data centers, batch processing facilities, and energy-intensive environments that demand fast response times and minimal legacy system disruption.
