Epoxy-encapsulated laminations provide rugged insulation and reduced core losses, translating to steadier output under varying loads. Copper windings deliver reliable current transfer with low signal loss. Molded-in terminals simplify field wiring and resist terminal creep in harsh environments. The transformer supports multiple primary voltages—220x440 V, 230x460 V, and 240x480 V—and a secondary of 120/115/110 V, rated at 300 VA. This flexibility reduces panel inventory and enables easier retrofits across different regions. In practice, it means faster installation and fewer parts to stock for 50/60 Hz automation setups. RoHS compliance and certifications ensure procurement accuracy and regulatory alignment, while the epoxy encapsulation and 55°C rating boost reliability in warm facilities. Compact dimensions (4.56 in x 4.5 in x 4.22 in) and a lightweight 11 lb design simplify OEM integration and serviceability. Copper windings and molded-in terminals reduce wiring errors and service time in dense control panels, improving overall maintenance metrics.

FAQs
For proper installation, mount the C0300E2A on a rigid surface with adequate ventilation to avoid heat buildup. Use molded-in terminals to simplify wiring and ensure secure terminations. Configure the primary to match 220–240 V supply, and verify the 50/60 Hz operation aligns with your control panel design. Maintain clearance around the device for cooling and inspection, and follow all RoHS and safety guidelines during installation.
The primary voltage options are 220x440 V, 230x460 V, and 240x480 V, allowing compatibility with regional power standards. The secondary voltage is 120/115/110 V, suitable for a range of control circuits. The unit is rated at 300 VA, with a 55°C insulation system, making it suitable for standard 50/60 Hz industrial environments and compact panel applications.
The C0300E2A is CSA Certified, UL Listed, and cUL Certified, ensuring compliance with recognized North American safety standards. This reduces procurement risk and streamlines audits. Additionally, it is RoHS Compliant, supporting environmental and regulatory requirements in modern manufacturing and helping with supplier qualification and cross-border deployments.
A 300 VA rating defines the maximum apparent power the transformer can deliver. For example, at 120 V secondary, the maximum current is 300 VA / 120 V ≈ 2.5 A; at 110 V, it's ≈ 2.73 A; and at 115 V, ≈ 2.61 A. Plan loads so the total secondary current remains below these values to avoid voltage drop or overheating in critical control circuits.
The MTE transformer is designed for 50/60 Hz operation with a 55°C temperature rating, epoxy encapsulation, and molded-in terminals for durability in harsh environments. Copper windings ensure efficient power transfer with low losses, while the RoHS compliance and multiple primary/secondary voltage options simplify integration into diverse automation architectures and improve long-term reliability and maintenance economics.
