Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang GE NEMA dari 3G Electric.
What coil voltages are available for GE NEMA enclosed non-reversing starters from 3G Electric?
3G Electric stocks GE NEMA enclosed non-reversing starters with electronic overloads in coil voltages of 120V AC, 240V AC, and 480V AC. These correspond to SKUs 6ANE9 (120V AC), 6VDJ8 (240V AC), and 6VDN1 (480V AC), all for NEMA Size 1, 27 A, three-pole configurations. The coil voltage determines the control circuit requirements for energizing the starter's magnetic coil.
What is the NEMA size and current rating of the GE starters supplied by 3G Electric?
The GE NEMA enclosed non-reversing starters available from 3G Electric are NEMA Size 1, rated for 27 amperes. NEMA Size 1 is a standard frame size for motor starters handling up to 27 A continuous current, suitable for motors up to approximately 7.5 HP at 460V AC. The electronic overload provides adjustable protection within this range.
Do these GE starters include auxiliary contacts and pilot lights?
Yes, the GE NEMA enclosed non-reversing starters supplied by 3G Electric include one normally open (1NO) auxiliary contact and a pilot light. The auxiliary contact can be used for status feedback or interlocking in control circuits, while the pilot light provides visual indication of the starter's energized state.
Are these GE starters suitable for three-phase motor applications?
Yes, these GE NEMA starters are three-pole devices designed for three-phase motor applications. They are non-reversing, meaning they provide forward rotation only. For reversing applications, a separate reversing starter or contactor arrangement would be required. The electronic overload protects against phase loss and overcurrent.
What type of overload protection do these GE starters use?
These GE NEMA starters use electronic overload relays instead of traditional thermal bimetallic overloads. Electronic overloads offer adjustable trip settings, improved accuracy, and features such as phase loss protection and trip class selection. This allows precise matching to motor full-load current and starting characteristics.
Can 3G Electric supply GE NEMA starters with different enclosure types?
The GE NEMA starters listed by 3G Electric are enclosed units, typically with NEMA 1 or NEMA 12 ratings for general-purpose indoor use. For specific enclosure types (e.g., NEMA 4X, NEMA 7), consult 3G Electric's catalog or request a quote, as availability may vary. The standard enclosures provide protection against dust and light moisture.
