Square D 9070TF100D5 Control Transformer 100 Va

Product Description

The SQUARE D 9070TF100D5 is a 100 VA control transformer with a top mount fuse block, designed for industrial and commercial control circuit applications. It steps down line voltage to a safe low-voltage control signal, powering contactors, relays, pilot lights, and other control devices. The fused top mount configuration allows for convenient overcurrent protection without adding external fuse holders. At 4.5 pounds and built to industrial standards, this unit is suited for panel builders, maintenance electricians, and automation technicians working on motor control centers, machine tool panels, and similar equipment.

This transformer is used in industrial control panels where a reliable, fused low-voltage supply is required. Typical applications include motor starters, PLC control circuits, HVAC rooftop unit controls, and commercial building automation panels. The top mount fuse block simplifies wiring access and keeps the control circuit protected at the transformer output. It is appropriate for both new panel builds and retrofit or replacement installations.

Key Features

• 100 VA capacity for powering low-voltage control circuits
• Top mount fuse block provides built-in overcurrent protection at the secondary
• Compact footprint at 8.1 inches long, 7 inches wide, and 6.2 inches tall
• 3.34 inches deep mounting profile for panel space efficiency
• 4.5 pound construction suited for standard DIN or panel mounting configurations

Compatibility

Designed as an OEM-style replacement control transformer for industrial and commercial control panels requiring a 100 VA top mount fused transformer in the SQUARE D 9070T series form factor.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the panel before mounting or wiring this transformer. Verify that primary voltage connections match the available line voltage before applying power. Do not exceed the 100 VA rated load on the secondary circuit.
