Square D 9070TF75D23 Control Transformer 75 Va

Product Description

The SQUARE D 9070TF75D23 is a 75 VA control transformer designed for industrial and commercial control circuit applications. It operates at both 50 and 60 Hz and features a top-mounted fuse block for integrated overcurrent protection on the secondary side. Licensed electricians and industrial maintenance technicians install this transformer to step down line voltage to safe control-circuit levels for motor starters, contactors, relays, and other low-voltage control devices. The fused design helps protect downstream control components and simplifies circuit protection without requiring a separate fuse holder. At 4.5 pounds, it is a compact and direct-fit replacement for standard control panel installations.

This transformer is suited for use in industrial control panels, HVAC equipment control circuits, and commercial machinery where a reliable 75 VA step-down transformer with built-in fuse protection is required. The top-mount fuse block configuration keeps fusing accessible for routine inspection and replacement. It is appropriate for both new installations and service replacement work in environments requiring 50 or 60 Hz operation.

Key Features

• 75 VA transformer capacity for standard control circuit loads
• Dual-frequency rated at 50/60 Hz for broad application compatibility
• Top-mounted fuse block provides integrated secondary overcurrent protection
• Fused configuration eliminates the need for a separate external fuse holder
• Compact form factor suitable for control panel enclosure installations

Compatibility

Designed as an OEM-style replacement control transformer for industrial and commercial control panel applications requiring a 75 VA top-mount fuse block transformer at 50/60 Hz.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panel before beginning any wiring work. Verify that primary voltage connections match the transformer tap configuration before applying power. Inspect the fuse block and install the correct fuse rating for the secondary circuit before energizing.
