Feature: 100 kA per phase surge current rating with a 200 kA short-circuit rating is engineered to absorb damaging transients before they reach motors and drives. Business Impact: significantly lowers the risk of insulation damage, arc flash events, and costly downtime during grid disturbances. Application: particularly effective in motor control centers and plant feeders where large transient events are common. Feature: Wide voltage rating from 200 V up to 277 V (200/208/230/240/277 V) with 50/60 Hz compatibility. Business Impact: enables use across common US three-phase and single-phase feeders, reducing inventory complexity and incorrect part selection. Application: MCCs, line feeders, and machine assemblies in mixed-voltage environments. Feature: Internal integrated mounting with built-in audible alarm, Form C relay contact, and surge counter with rest button. Business Impact: streamlines installation, provides immediate notification, and enables PLC or HMI monitoring for proactive protection. Application: centralized protection programs and remote diagnostics across multiple MCC sections. Feature: EMI/RFI filtering delivering up to 50 dB attenuation from 10 kHz to 100 MHz. Business Impact: reduces electrical noise that can cause drive instability and PLC misoperation, improving overall control reliability. Application: drives, sensors, and instrumentation in noisy industrial environments. Feature: 15-year warranty and UL 1449 Listed certification. Business Impact: lowers lifecycle cost and reinforces regulatory compliance for critical equipment protection. Application: long-term deployment in manufacturing lines and process facilities requiring durable protection. Feature: Used with motor control centers and designed with internal mounting for easy integration. Business Impact: minimizes installation complexity and enables quick rollout across new or existing MCCs. Application: retrofit projects and new plant builds where compact, integrated protection is valued.

FAQs
SPD100230L3J should be installed in MCC sections with appropriate voltage rating (200–277 V) and 50/60 Hz supply. Mount internally as designed, connect to the protected feeders, and wire the Form C relay and surge counter to the PLC or annunciator. Ensure compliance with UL 1449 requirements and maintain a clear access path for the audible alarm.
Key specs include a surge current rating of 100 kA per phase, a short-circuit rating of 200 kA, and a nominal discharge current of 20 kA. Voltage rating spans 200 V to 277 V, with 50/60 Hz operation. Operating temperature is -40 to 50 °C, and mounting is internal integrated for MCC installations.
No. SPD100230L3J is rated for 200–277 V (and associated 50/60 Hz operation). For 480 V systems, a model with a higher voltage rating is required to ensure proper protection without compromise to performance or safety.
The device is UL 1449 Listed, ensuring compliance with recognized safety standards for surge protective devices. It is designed to meet building standards such as IBC 2006, CBC 2007, and UBC Zone 4, supporting regulatory alignment for industrial facilities and retrofit projects.
The SPD includes a surge counter with a rest button, an audible alarm, and a Form C relay for remote signaling. These features support proactive maintenance, easier fault diagnosis, and rapid response to protection events, reducing unplanned downtime and extending MCC life — contributing to a favorable return on investment.
