Square D 9070TF200D20 Control Transformer 200 Va

Product Description

The SQUARE D 9070TF200D20 is a single-phase control transformer rated at 200 VA, designed to step down line voltage to low-voltage control circuit levels in industrial and commercial electrical systems. It features a top-mounted fuse block for overcurrent protection of the secondary circuit, keeping the fuse accessible without removing the unit from its mounting position. Rated for a 176 degrees F temperature rise, this transformer is built for continuous-duty control applications where reliable voltage conversion is required. Electricians and industrial maintenance technicians install this unit as part of motor control centers, machine control panels, and automated equipment enclosures.

This transformer is suited for single-phase control circuit applications in commercial and light industrial settings. Typical installations include motor starters, contactor control circuits, PLC input power supplies, and HVAC equipment control panels where a dedicated low-voltage control circuit is required. The top-mount fuse block configuration is commonly specified in panel layouts where secondary fusing must remain serviceable during routine maintenance without full panel shutdown.

Key Features

• 200 VA single-phase rating supports a range of control circuit loads
• Top-mounted fuse block provides accessible secondary circuit overcurrent protection
• 176 degrees F temperature rise rating supports continuous-duty operation
• Compact footprint at 6.5 inches tall, 6.8 inches wide, and 7.6 inches in length
• Fused configuration reduces external fusing requirements for the secondary circuit

Compatibility

Designed as an OEM-style replacement for single-phase control transformers in industrial and commercial control panel applications requiring a top-mount fused secondary configuration.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for control transformers and panel wiring. De-energize and lock out all primary power sources before mounting or making connections. Verify primary and secondary voltage taps match the system requirements before energizing. Ensure the fuse block is loaded with the correct fuse rating for the secondary circuit load before returning the panel to service.
