Acme Electric T253009S Distribution Transformer 0.75 Kva

Product Description

The ACME ELECTRIC T253009S is a single-phase, 0.75 KVA low-voltage distribution transformer designed for industrial and commercial power distribution applications. It accepts a dual primary voltage of 240 x 480 volts and delivers a secondary voltage of 120/240 volts at 50/60 Hz. The unit features an encapsulated, totally enclosed construction using electrical-grade silica and resin compounds that fully seal the core and coil assembly against moisture and air intrusion. Housed in a stainless steel NEMA 3R enclosure, it is rated for both indoor and outdoor installation. Licensed electricians and electrical contractors handle installation on commercial and industrial service equipment.

This transformer is suited for wall-mounted installation in industrial facilities, commercial buildings, and light manufacturing environments where a stepped-down single-phase supply is needed from a 240-volt or 480-volt distribution panel. The NEMA 3R enclosure rating makes it appropriate for outdoor-rated service locations exposed to rainfall or falling dirt. Its compact footprint of 4.75 inches wide by 4.5 inches deep by 9.68 inches tall allows installation in tight electrical rooms or on equipment panels. The unit is listed to UL and CSA standards and conforms to NEMA ST-20, NEC, and ANSI requirements, making it suitable for code-compliant commercial and industrial installations.

Key Features

• Dual primary voltage input: 240 x 480 volts for flexible connection to existing distribution systems
• Shielded winding design for reduced electrical noise and cleaner secondary power output
• Sound level rated well below NEMA standards for quiet operation
• UL and CSA listed; meets NEMA ST-20, NEC, and ANSI applicable standards

Compatibility

Designed as an OEM-style replacement or new-installation distribution transformer for single-phase, low-voltage commercial and industrial power distribution systems requiring 240 x 480-volt primary input and 120/240-volt secondary output.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code and applicable local codes. De-energize and lockout/tagout the upstream circuit before making any wiring connections. The unit is rated for wall mounting and should be secured to a structural surface capable of supporting the transformer weight. Verify primary voltage tap selection matches the supply voltage before energizing.
