Hammond SP500MQMJ Control Transformer 500VA

Product Description

The HAMMOND SP500MQMJ is a 500 VA control transformer designed to step down line voltage to a lower control-circuit voltage in industrial and commercial electrical systems. Control transformers of this class are used to power relay logic, motor starters, solenoid valves, and other control components that require a stable, isolated voltage supply. At 500 VA, this unit handles moderate control-panel loads. A licensed electrician or controls technician typically installs this transformer during panel builds or service calls requiring transformer replacement.

The SP500MQMJ is suited for use in commercial and light industrial control panels, HVAC equipment, machine tool circuits, and process control applications. It is appropriate wherever a reliable step-down transformer is needed to supply low-voltage control circuits from a higher line-voltage source. Typical installations include motor control centers, packaged HVAC rooftop units, and automated equipment enclosures.

Key Features

• 500 VA capacity supports moderate control-panel loads
• Designed for control-circuit isolation in industrial and commercial applications
• Compatible with relay logic, motor starters, and solenoid valve coils
• Compact form factor suitable for panel or enclosure mounting

Compatibility

Designed as an OEM-style replacement or new-installation control transformer for commercial and industrial control panels requiring 500 VA capacity.

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 before removing or installing the transformer. Verify that primary and secondary voltage ratings match the application requirements before wiring. Ensure the transformer is properly grounded and that the VA rating meets or exceeds the total connected control-circuit load.
