Overview
The SolaHD E300EWB is a 300 VA industrial control transformer from the SBE Series. It features an epoxy-encapsulated construction with copper windings for durability. The unit supports chassis mounting and includes a pre-installed primary fuse block (Class CC) along with a built-in midget-type secondary fuse. It operates at 60 Hz and meets UL (Canada and US) approval standards under ANSI/NEMA ST-1.
Feature Summary
- Epoxy-encapsulated design for enhanced environmental protection
- Integrated primary Class CC fuse block and secondary midget fuse
- Copper-wound laminated core construction
- Chassis mount installation configuration
Applications
- Industrial control panel power distribution
- Machine tool auxiliary power supply
- Enclosed equipment voltage transformation
- Control circuit isolation and stepping
Procurement Notes
Verify the specific voltage configuration matches the application requirements, as the E300EWB typically denotes a 120 x 240 VAC primary to 24 VAC secondary setup. Confirm that the chassis mounting dimensions align with the enclosure layout. Ensure the integrated fuse ratings are compatible with the downstream circuit protection needs. Check lead times due to potential manufacturing delays.
Selection Notes
Select this model when a robust, encapsulated transformer is required for harsh industrial environments. The built-in fusing simplifies design by reducing component count. Verify that the 300 VA rating adequately covers the connected load. Consider the physical dimensions of 5.99 inches in height for spatial planning within the control cabinet.
Part Context
This component belongs to the SolaHD SBE Encapsulated Series, designed for heavy-duty industrial applications. It complements other transformers in the E300E family, such as the E300EW, differing primarily in the inclusion of built-in fusing and specific encapsulation details. The series adheres to ANSI/NEMA ST-1 standards for reliability.
Replacement Considerations
Direct replacements may include the E300EW if fusing is not critical, or other 300 VA encapsulated models from the same manufacturer. Verify that substitute parts maintain the same primary/secondary voltage ratios and physical footprint to ensure compatibility with existing wiring and mounting hardware.
