Product Overview
The Gefran GTF-90-480-2-1-0-M 1-B-M, ordering code F052303, is a 90 A single-phase solid-state power controller for industrial electrical heating systems. It combines configurable firing control, current limiting, signal feedback, load diagnostics and Modbus RTU communication in a compact cabinet-mounted unit.
Main Features
- 90 A nominal current rating.
- 480 VAC nominal voltage class with a documented 90–530 VAC operating range.
- Burst-firing control for compatible industrial loads.
- Current limiter and current-monitoring functions.
- Feedback support for voltage, current and power variables.
- Modbus RTU communication and one solid-state alarm output.

Compatible System and Applications
The controller supports compatible resistive loads, low-inductance loads, short-wave infrared lamps and transformer applications. The correct firing mode depends on the load. Heater current, conductor size, external fuse, cabinet temperature, mounting clearance and ventilation must be calculated for the actual installation.
Maintenance and Replacement Notes
Disconnect the mains supply and verify that hazardous voltage is absent before service. Record the command-input selection, firing mode, Modbus settings, feedback mode and current limit. Inspect the heatsink, terminals and airflow before commissioning a replacement.
Related Models
GTF-25-480-2-1-0-M 1-B-M and GTF-40-480-2-1-0-M 1-B-M use lower current ratings. GTF-60 and GTF-75 occupy intermediate current classes. Versions with 3-B-M, 4-B-M or 4-P-M codes have different hardware or mounting configurations and different F-codes. Related models are provided for family reference only and are not automatically interchangeable.
Inquiry and Supply Notes
Provide F052303 and the complete GTF-90-480-2-1-0-M 1-B-M code with the inquiry. The shortened GTF-90-480 search term is not sufficient for ordering. Only one qualifying exact-configuration new quotation supported the price calculation, so the suggested price is provisional.
