Description

GE 9T21J1708

Technical Specifications:

  • Brand: General Electric (GE)
  • Model: 9T21J1708
  • Product Type: Industrial Control Relay
  • Contact Configuration: Multi-pole, high-capacity

Functional Features:

  • High Current Switching: Capable of handling significant inrush and continuous currents.
  • Mechanical Interlocks: Prevents accidental operation or ensures safe sequencing.
  • Visible Contacts: Allows visual verification of contact position.

Application Scenarios:
Used in motor control centers, safety interlock circuits, and industrial ovens.

Performance Parameters:

  • Electrical Life: Hundreds of thousands of load cycles.
  • Dielectric Strength: High isolation between coil and contacts.

Material Composition:
Silver-alloy contacts, phenolic housing, and high-temperature coil insulation.

Structural Characteristics:
Modular design with plug-in or socket-mount options, and indicator flags.

Working Principle:
Energizing the coil creates a magnetic field that moves the armature, closing or opening the contacts to control the load circuit.

Installation Requirements:
Mount vertically for proper operation. Ensure socket contacts are clean and tight.

Usage Precautions:
Never exceed rated voltage/current. Inspect contacts periodically for pitting or carbon buildup.
