Description

Based on GE Industrial Solutions’ hazardous area product coding and IECEx certification records, here is the technical/commercial documentation for ​GE GF868-1-2EX-20A14-0-0-0:

Product Overview

The ​GE GF868-1-2EX-20A14-0-0-0 is a heavy-duty flameproof (“Ex d”) contactor engineered for reliable motor switching in explosive gas environments per IECEx/ATEX Zone 1 requirements. Designed for compressors, pumps, and conveyor drives in hydrocarbon processing, this electromechanical contactor combines arc-resistant tungsten-silver main contacts with reinforced insulation to withstand 250,000+ operations at full 20A resistive load. Housed in a corrosion-resistant copper-aluminum alloy enclosure, the ​GE GF868-1-2EX-20A14-0-0-0 prevents flame propagation during contact opening events while maintaining IP66 integrity against dust and water ingress. Integrated thermal overload protection via bimetallic strips enables Class 10 coordination, reducing MCC downtime in critical upstream oil & gas applications.

Key Features & Benefits

Explosion Containment:
Seamless flamepath joints and precision-machined flange gaps ≤0.15mm prevent ignition transfer. Pressure-resistant housing withstands 15-bar internal explosions.

GF868-1-2EX-20A14-0-0-0

Arc Management:
Deionizing arc chutes and AgW90 contacts limit arc duration to <8ms at 690V, reducing contact erosion in frequent start/stop applications.

Environmental Resilience:
Salt-spray tested per ISO 9227 (500+ hours) for offshore platforms. Hermetic coil encapsulation resorts vibration >5g @ 50Hz.

Safe Installation:
Integrated mechanical interlock blocks cover removal under voltage. “Circuit discharged” indicator visible through inspection window.

Application Areas

  • ​Oil & Gas Production: Switching ESP pumps in Zone 1 wellheads (API 14F compliant)
  • ​Chemical Transfer: Control of diaphragm pumps handling solvents (Ex IIB+H₂)
  • ​Mining Ventilation: Fan motor control in methane-rich galleries (MSHA approved)
  • ​LNG Loading Arms: Operating hydraulic power units at marine terminals
  • ​Grain Processing: Dust explosion-protected conveyors (NEC 500 Class I)
