Special features
Primary fuse block
Epoxy encapsulated construction with high-quality silicon steel laminations minimizes core losses and improves heat management, reducing energy waste and extending service life in continuous-duty automation panels. Copper windings promote efficient energy transfer and improved voltage regulation, delivering stable control signals to PLCs and relays in demanding applications. The 208/277 V primary to 120 V secondary configuration simplifies integration with typical plant power distribution, enabling rapid panel design and fewer converters. A factory-mounted two-pole primary fuse block enhances safety and reduces field wiring during installation, delivering faster commissioning and fewer wiring errors. Molded-in terminals resist vibration and environmental wear, increasing reliability in harsh industrial environments. The 55°C insulation system supports hotter enclosures, while RoHS compliance and multiple certifications (UL, CSA, cUL) ensure regulatory alignment for safe machine builds.
