Specifications

Pomanique's GX Series Recloser three-phase, electronically controlled, vacuum-interrupting distribution automation switch provides reliable, economical switching, sectionalizing, advanced metering and automation systems for distribution circuits rated up to 38 kV.

The GX Series Recloser combines solid insulation vacuum interrupters with a reliable, lightweight operating mechanism that utilizes a magnetic actuator to provide a lifetime of trouble-free operation. The solid polymer system does not rely on a gaseous, liquid or foam dielectric. The GX Series Recloser is highly resistant to ozone, oxygen, moisture, contamination and ultraviolet light.

Switch operations are programmed in an electronic control with accurate characteristics and a host of advanced features. When system requirements change, program settings are easily altered with no sacrifice of accuracy or consistency.

Pomanique's reclosers meet all the requirements for outdoor use in accordance with IEEE C37.60 and IEC 62271-111.

Product questions, answered

Clear guidance on selection, documentation, customization and project delivery.
Please provide the application, system rated voltage and frequency, continuous load current, short-circuit level, insulation level or BIL, and the required operating duty. Also include indoor or outdoor installation, altitude, ambient temperature, pollution level, control voltage, communication requirements, quantity, destination market and applicable standard. A single-line diagram, existing nameplate or project specification will make the review more accurate.
A recloser is generally used for automatic fault interruption and service restoration on distribution feeders. A circuit breaker provides repeated fault interruption, a load break switch is intended for rated-load switching within its specified capability, a disconnector provides an isolation point, and a fuse provides single-operation overcurrent protection. The final choice must be based on load current, fault level, protection coordination, switching frequency, installation method and operating philosophy.
Confirm the voltage class, frequency, rated current, short-circuit breaking and making duties, insulation level, creepage distance, mechanical or electrical endurance, enclosure protection, control supply and auxiliary contacts. The applicable IEC, IEEE, ANSI, GB or project-specific requirement should be stated in the inquiry. The approved data sheet and drawing, rather than only a general product family name, define the final supply.
Yes, a technical comparison can be made when sufficient information is available. Please send the existing model and nameplate, general arrangement and mounting dimensions, terminal interfaces, wiring diagram, interlocks, operating mechanism and electrical ratings. Similar voltage and current ratings do not by themselves confirm mechanical or electrical interchangeability, so approval is required before replacement.
Selection should consider the system grounding method, maximum continuous operating voltage, temporary overvoltage, required protective level, system insulation level, altitude, pollution severity and creepage distance. Mechanical loading, housing material and installation orientation also matter for outdoor equipment. Provide the system and site data so insulation coordination can be reviewed as a complete set.
Customization can be evaluated according to technical feasibility, validation requirements and order quantity. Typical requests include labels and packaging, terminal arrangements, mounting dimensions, control voltages, transformer ratios, accessories, communication functions and project documentation. Customized production should begin only after the technical specification and approved drawings are confirmed by both parties.
