Square D 9070TF500D33 Control Transformer 500 Va

Product Description

The SQUARE D 9070TF500D33 is a 500 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 control-level voltage, protecting low-voltage control circuits in motor control centers, panel boards, and machine tool wiring. The fused top mount configuration allows quick fuse inspection and replacement without disturbing field wiring. At 12.63 pounds, this is a robust unit built for demanding service environments. Licensed electricians and industrial maintenance technicians are the typical installers.

This transformer is suited for use in commercial and industrial settings where reliable control-circuit power is required. Typical applications include motor starters, contactors, solenoid valves, and relay logic panels. The top mount fuse block provides overcurrent protection for the secondary control circuit, a common requirement in machine tool and process control installations. It is packaged as a single unit and is intended as a direct replacement or new-installation component in control panel assemblies.

Key Features

• 500 VA rated capacity for control circuit power delivery
• Top mount fuse block provides accessible overcurrent protection for the secondary circuit
• Fused secondary design reduces risk of control circuit damage from short circuits or overloads
• Compact footprint at 6.7 inches wide, 7.7 inches in length, and 6.5 inches tall
• Weighs 12.63 pounds, indicating heavy-duty core and coil construction
• Single-unit packaging suitable for individual panel builds or replacement service

Compatibility

Designed as an OEM-style replacement or upgrade control transformer for commercial and industrial control panel assemblies requiring a 500 VA top mount fused transformer configuration.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NFPA 70 (NEC) Article 430 and applicable local codes. De-energize and lock out the panel before mounting or wiring this transformer. Verify primary tap voltage matches the supply voltage before energizing. Ensure the fuse rating installed in the top mount fuse block is appropriate for the secondary load to maintain proper overcurrent protection.
