Appleton HS19B250 Control Transformer 0.250 Kva

Product Description

The APPLETON HS19B250 is a heavy-duty control transformer rated at 0.250 KVA with a 120x240-volt primary and a 12/24-volt secondary. Control transformers step down line voltage to the low-voltage levels required to power control circuits in industrial and commercial equipment. This unit is built for demanding service environments and is installed by licensed electricians on equipment control panels, HVAC systems, and industrial machinery where reliable low-voltage control power is essential. At 8 pounds, it is a compact but substantial unit suited for panel mounting in fixed installations.

This transformer is used in applications where control circuits require stable low-voltage power derived from a standard 120-volt or 240-volt single-phase supply. Typical installation scenarios include motor control centers, packaged HVAC equipment, process control panels, and machine tool wiring. The dual primary voltage configuration allows the installer to connect to either a 120-volt or 240-volt source, providing flexibility across a range of commercial and industrial electrical systems.

Key Features

• 0.250 KVA transformer capacity suitable for low-voltage control circuit loads
• Dual primary voltage input: 120 volts or 240 volts for installation flexibility
• 12/24-volt secondary output for standard low-voltage control circuits
• Heavy-duty construction rated for commercial and industrial service environments
• Compact form factor at 8 pounds for panel or enclosure mounting

Compatibility

Designed as an OEM-style replacement or new-installation control transformer for commercial and industrial control panels requiring a 0.250 KVA, 120x240-volt primary to 12/24-volt secondary configuration.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the panel or equipment before removing an existing transformer or making any wiring connections. Verify that the primary tap is connected to match the available supply voltage before energizing. Ensure the transformer is mounted securely and that secondary circuit loads do not exceed the rated KVA capacity.
