Product Overview

The Gefran GTF-25-480-2-1-0-M 1-B-M, ordering code F052299, is a 25 A single-phase solid-state power controller for regulating electrical heating loads in industrial thermal processes. The GTF platform combines microprocessor control, configurable firing modes, current monitoring, load diagnostics and serial communication in a compact cabinet-mounted device.

Main Features

• Nominal current class of 25 A.
• Nominal load-voltage class of 480 VAC.
• Configurable zero-crossing and burst-firing operating modes at series level.
• Current-limit and RMS-current monitoring functions.
• Feedback functions for supported voltage, current and power variables.
• Modbus RTU communication associated with the M configuration.

Technical Specifications

Compatible System and Applications

Typical applications include industrial furnaces, plastics-processing heaters, packaging and sealing machines, drying systems and other single-phase resistive heating circuits. Load resistance, operating voltage, inrush behavior, thermal design and protective devices must be calculated for the actual installation.

Maintenance and Replacement Notes

Disconnect the mains supply and confirm the absence of hazardous voltage before service. Inspect the heatsink, ventilation, power terminals and protective devices. Record the control-input configuration, Modbus address, firing mode and current-limit settings before replacing the unit.

Related Models

GTF-40-480-2-1-0-M 1-B-M increases the nominal current class to 40 A. GTF-60, GTF-75 and GTF-90 versions cover higher current classes. Configurations ending in 4-P-M, 1-P-M or HS include different mounting, cooling or option codes and carry different F-codes. Related models are provided for family reference only and are not automatically interchangeable.

Inquiry and Supply Notes

Provide F052299 and the complete GTF-25-480-2-1-0-M 1-B-M model, not only the shortened Google search term. Include the heater voltage, calculated load current, control signal and cabinet conditions.
