🔹 WOTPC Automatic Transfer Switch – OT40003D5I (3 Pole, 4000A Class, Industrial ATS)
🔹 Product Description
The WOTPC OT40003D5I is a high-capacity Automatic Transfer Switch (ATS) designed for seamless and reliable switching between main utility power and standby generator supply in large-scale electrical systems. It ensures uninterrupted power delivery by automatically transferring the load when the primary source fails and restoring it once the supply is stable again.
This model belongs to the heavy-duty WOTPC PC-Class ATS series, engineered for critical infrastructure where continuous power availability is essential. The OT40003D5I is specifically designed for extremely high load applications, making it suitable for large industrial and commercial power distribution networks.
With a 3-pole configuration, it is ideal for three-phase electrical systems. The switch ensures safe isolation between two power sources, preventing back-feed and maintaining system safety during switching operations. Its robust construction supports high fault levels and frequent operations in demanding environments.
The OT40003D5I is widely used in MCC/PCC panels and integrates with modern power management systems, offering both automatic and manual operation modes depending on system design. It is built for long mechanical life, high reliability, and fast transfer response in emergency conditions.
