General Electric CR305X100E Auxiliary Contact Adder Block 1 Normally Closed

General Electric CR305X100E 1 NC Auxiliary Contact Adder Block for 300-Line Contactors

The General Electric CR305X100E is a single-circuit auxiliary contact adder block designed for use with GE 200- and 300-Line magnetic contactors and starters. This unit provides one normally closed contact and installs directly onto an existing basic auxiliary contact block as a field modification.

Normally Closed Auxiliary Contact Configuration

• Single normally closed (1 NC) auxiliary contact
• Non-convertible contact configuration
• Heavy pilot-duty contact construction
• Double-break contact design

Electrical Ratings and Contact Design

The CR305X100E auxiliary contact block is rated for control circuit use with maximum voltages up to 600 VAC and 250 VDC. The internal contacts are of double-break design, supporting reliable operation in pilot-duty applications when installed within compatible GE contactor assemblies.

Application with GE 200- and 300-Line Devices

• Expansion of control circuits on GE 200-Line starters and contactors
• Expansion of control circuits on GE 300-Line starters and contactors
• Field-installed auxiliary contact additions where a normally closed signal is required
