Primary fuse block
Epoxy-encapsulated construction with laminations of high-quality silicon steel minimizes core losses and improves efficiency, even in demanding 50/60 Hz environments. This translates to cooler operation, longer life, and reduced energy waste in continuous panel duties. Copper windings enhance conductivity and thermal performance, sustaining stable voltages to relays and PLC inputs while maintaining reliable operation under load surges. Primary voltage is 208/277 V with a 120 V secondary and a 500 VA rating, delivering sufficient power for typical control circuits without overdimensioning the panel. Molded-in terminals simplify wiring, increase vibration resistance, and support durable field connections in busy industrial cabinets. The epoxy encapsulation and rugged enclosure support rugged installation in harsh environments, while RoHS compliance and UL/cUL/CSA certifications provide regulatory assurance and peace of mind for multi-region projects. With a compact footprint (approximately 6.11 in × 5.25 in × 5.14 in) and a weight around 17.4 lb, it fits standard control panels and withstands routine maintenance without frequent reconfiguration. This transformer is designed for reliability, easy troubleshooting, and predictable performance across a range of industrial applications.
