Product Overview

The Gefran GTF-40-480-2-1-0-M 1-B-M, ordering code F054982, is a 40 A single-phase solid-state power controller for industrial electrical heating systems. It provides microprocessor-based load control, configurable firing strategies, current limiting, diagnostic functions and Modbus communication for integration with a PLC, HMI or supervisory controller.

Main Features

• 40 A nominal current class.
• 480 VAC nominal load-voltage class.
• Configurable zero-crossing and burst-firing modes.
• Current-limit functions for supported heating applications.
• Voltage, current and power feedback capabilities supported by this configuration family.
• Modbus RTU serial communication.

Technical Specifications

Compatible System and Applications

The controller is suitable for furnaces, extruder heating zones, textile machinery, packaging equipment, food-processing heaters, paint-drying ovens and similar thermal systems. Actual usable current depends on ambient temperature, mounting spacing, ventilation, switching mode and load characteristics. The 40 A designation must not be used as the sole basis for cabinet design.

Maintenance and Replacement Notes

Isolate the mains supply before touching the controller or load terminals. Verify protective earth, external fuse coordination, heatsink condition, airflow and conductor sizing. Save the firing mode, command-input selection, Modbus parameters, current limit and diagnostic thresholds before replacing the existing controller.

Related Models

GTF-25-480-2-1-0-M 1-B-M uses a lower 25 A current class. GTF-60-480-2-1-0-M, GTF-75-480-2-1-0-M and GTF-90-480-2-1-0-M cover higher current classes. GTF-40 configurations with 4-P-M or 4-B-M suffixes use 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

Specify F054982 and the complete GTF-40-480-2-1-0-M 1-B-M configuration with the inquiry. The shortened GTF-40-480 term is insufficient for ordering. USD 471/Unit is based on a small group of exact-configuration new distributor quotations converted to USD and multiplied by 70 percent; it remains a limited-sample upload price.
