Overview
The General Electric CR306C0 is a full-voltage magnetic motor starter rated for 600VAC maximum with a continuous current rating of 27A. The CR306C0 has an encapsulated coil and a 3-leg overload relay to protect against overloads in all phases. GE’s magnetic motor starters may be used for starting full-voltage, nonreversing, single-speed ac motors up to 1600 horsepower, 600 Volts maximum, providing protection to the motor against running or stalled overloads.
Key Features
- Encapsulated coil with 3-leg overload relay for comprehensive phase protection
- Class 20 overload protection with manual reset and base-mounted NO auxiliary trip indicating contact
- Wide range of accessories including auxiliary contacts, mechanical interlocks, surge suppressors, and control circuit fusing options
- Toolless contactor disassembly on sizes 00-4 allows quick access for inspection and maintenance without tools
- NEMA rated three-phase design with thermal overload relays requiring 3 bimetal heaters for complete motor protection
- Compact size and ease of wiring make it suitable for motor control centers, custom-type control panels, and switchgear equipment
Technical Specifications
The CR306C0 is configured as a NEMA Size 1 starter with standardized electrical characteristics for industrial motor control applications.
