Description

GE CR306G004

Technical Specifications

  • Product Type: Motor Starter / Contactor.
  • Series: GE CR306.
  • Horsepower Rating: Sized for specific motor HP/kW ratings.
  • Voltage Rating: Rated for standard industrial AC voltages (e.g., 600VAC).

Functional Features

  • Power Switching: High-capacity contacts for motor inrush and running currents.
  • Overload Protection: Integrated thermal or electronic overload relay to prevent motor burnout.
  • Auxiliary Contacts: Provides interlocking and status feedback to control circuits.

Application Scenarios

  • Industrial Motors: Pumps, fans, compressors, and conveyors.
  • Motor Control Centers (MCC): Individual motor bucket installation.

Performance Parameters

  • Contact Life: High electrical and mechanical endurance ratings.
  • Overload Trip Class: Configurable trip class for motor starting characteristics.

Material Composition

  • Contacts: Silver alloy for low resistance and arc resistance.
  • Enclosure: NEMA-rated enclosure for environmental protection.

Structural Characteristics

  • Design: Compact, modular design for space-efficient panel layout.
  • Wiring: Pre-wired or field-wired terminal options.

Working Principle
The contactor coil energizes to close the main power contacts, applying voltage to the motor. The overload relay continuously monitors motor current; if an overcurrent condition persists beyond the trip curve, it opens the control circuit to de-energize the contactor.

Installation Requirements

  • Size the starter correctly based on motor Full Load Amps (FLA).
  • Set the overload relay to the motor’s nameplate FLA.
