Universal 1110-246-C-TC

Universal 1110-246C-TC – 250W M58 Metal Halide CWA Ballast | 120V / 277V | Internal Capacitor | No Ignitor

The Universal 1110-246C-TC is a thermally protected 250W magnetic HID ballast designed to operate an ANSI M58 metal-halide lamp on either a dedicated 120V or 277V supply. It uses a constant-wattage autotransformer (CWA) circuit, includes an internal capacitor, and does not use a separate ignitor. The ballast draws 295 input watts, provides a minimum power factor of 90%, and is rated for 60Hz operation. This is a heavy magnetic ballast intended for compatible commercial and industrial HID fixtures. Please verify ANSI lamp code, supply-voltage tap, fixture dimensions, ballast wiring, capacitor configuration, and thermal requirements before ordering.

Technical Specifications

Key Features & Benefits

• Designed specifically for one 250W ANSI M58 probe-start metal-halide lamp.
• Dedicated 120V and 277V input leads support two common commercial supply voltages.
• CWA magnetic circuit helps regulate lamp wattage during normal line-voltage variation.
• Internal capacitor eliminates the need to mount a separate external capacitor.
• No ignitor is required for the M58 probe-start lamp circuit.
• Thermally protected construction helps protect the ballast from abnormal overheating.
• Copper primary and secondary coils support traditional heavy-duty magnetic-ballast construction.
• Rated for cold starting down to -22°F / -30°C.

Product Overview

The Universal 1110-246C-TC is a traditional magnetic HID ballast designed for commercial and industrial fixtures using a 250W ANSI M58 probe-start metal-halide lamp. Its CWA circuit combines the ballast transformer and power-factor-correction capacitor into a regulated HID operating system.

The ballast includes separate input leads for 120V and 277V service. It is not an electronic universal-input ballast and should not be connected to intermediate voltages. The unused input lead must be individually insulated according to the wiring diagram and applicable electrical codes.

Because this ballast weighs approximately 18 lb and measures nearly 17 inches long, mounting space and fixture structural support should be verified carefully. The internal capacitor and no-ignitor configuration must also match the original fixture design.

Compatible Applications

• Commercial fixtures designed for 250W M58 metal-halide lamps
• Industrial high-bay and low-bay HID fixtures
• Warehouse and manufacturing-area lighting
• Outdoor area luminaires designed for this ballast and lamp system
• Maintenance replacement of matching CWA magnetic HID ballasts
• Fixtures with adequate space and support for an 18 lb magnetic ballast

Before Ordering – Verify

• Model number: Confirm the required ballast is 1110-246C-TC.
• ANSI lamp code: Verify the fixture uses a 250W M58 probe-start metal-halide lamp.
• Do not substitute by wattage alone: Other 250W metal-halide, pulse-start metal-halide, or high-pressure sodium lamps may require different ballasts and ignitor circuits.
• Input voltage: Confirm the branch circuit is either 120V or 277V. This is not a continuously rated 120–277V electronic ballast.
• Frequency: The ballast is specified for 60Hz operation.
• Capacitor: This model uses an internal capacitor; verify the original fixture does not require a separate external capacitor configuration.
• Ignitor: No ignitor is used. Do not substitute it for a pulse-start system requiring an ignitor.
• Dimensions: Confirm approximately 16.75-inch overall length, 3.25-inch width, and 2.75-inch height.
• Weight: Confirm the fixture and mounting surface can safely support an 18 lb ballast.
• Sound rating: The ballast has a sound rating of C and may not be appropriate for noise-sensitive interior spaces.
• Wiring: Verify the 120V black/yellow lead, 277V black lead, white common lead, and lamp leads against the manufacturer wiring diagram.
• Unused voltage lead: Individually insulate the unused input-voltage lead with proper electrical insulation.

Safety and Installation Guidelines

• Disconnect and lock out electrical power before inspecting, wiring, installing, or removing the ballast.
• Use only with a compatible 250W ANSI M58 probe-start metal-halide lamp.
• Connect only the input lead matching the actual branch-circuit voltage.
• Insulate the unused input lead individually with a listed electrical connector.
• Ground the ballast housing and fixture according to the wiring diagram, National Electrical Code, and local requirements.
• Use the recommended branch-circuit protection appropriate for the selected voltage and installation.
• Do not use the ballast if its case, wiring, insulation, or leads are damaged.
• Maintain fixture ventilation and clearance from combustible materials.
• Secure the heavy ballast using all required mounting points and suitable hardware.
• Do not add an external ignitor to this circuit.
• Professional installation by qualified electrical personnel is strongly recommended.
