Square D 9070TF50D2 Control Transformer 50 Va

Product Description

The SQUARE D 9070TF50D2 is a single-phase, 50 VA control transformer designed to step down line voltage to a lower control-circuit voltage in industrial and commercial electrical systems. It features a top-mounted fuse block, providing overcurrent protection directly at the transformer and simplifying circuit protection without requiring a separate fusing assembly. Rated at 50 VA, this unit is well suited for powering control circuits in motor starters, contactors, relays, and similar low-load industrial control applications. Licensed electricians and controls technicians are the typical installers for this class of transformer.

This transformer is used in industrial control panels, HVAC packaged equipment, and commercial electrical enclosures where a dedicated, fused control-voltage source is required. The top-mount fuse block configuration keeps the fusing point accessible for maintenance without disturbing the transformer wiring. It fits applications that call for an OEM-style replacement or new-installation single-phase control transformer in the 50 VA class.

Key Features

• 50 VA single-phase rating suitable for control-circuit loads such as contactors and relay coils
• Integrated top-mount fuse block provides overcurrent protection at the source
• Fused configuration eliminates the need for an external fuse holder in the control circuit
• Compact footprint designed for panel or enclosure mounting
• Single-package quantity, sold individually

Compatibility

Designed as an OEM-style replacement or direct-install single-phase control transformer for industrial control panels and commercial HVAC or electrical systems requiring a 50 VA fused control-circuit transformer.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the panel or enclosure before removing the existing transformer or making any wiring connections. Verify that the primary voltage tap matches the available line voltage before energizing. Inspect the fuse block and install the correct fuse rating for the control-circuit load before returning the circuit to service.
