Description

GE TKMA31000

Technical Specifications:

  • Brand: General Electric (GE)
  • Model: TKMA31000
  • Product Type: Trip Unit / Breaker Accessory
  • Application: Industrial Circuit Protection

Functional Features:

  • Precision Tripping: Accurately detects overcurrent, short circuit, and ground fault conditions.
  • Adjustable Settings: Allows field-adjustable trip thresholds and time delays for optimal system coordination.
  • Alarm Outputs: Provides auxiliary contacts to signal pre-trip alarms or breaker status to the control system.

Application Scenarios:
Deployed in motor control centers, power distribution panels, and industrial machinery to protect cables, transformers, and motors.

Performance Parameters:

  • Accuracy: Tight tolerance on trip points to prevent nuisance tripping while ensuring equipment protection.
  • Response Time: Fast mechanical response to clear faults before they cause thermal damage.

Material Composition:
Precision current transformers, solid-state electronics, and high-reliability electromechanical relays.

Structural Characteristics:
Compact plug-in or front-mount design with accessible adjustment dials, test buttons, and clear rating labels.

Working Principle:
Continuously monitors the current flowing through the circuit breaker. When the current exceeds the programmed threshold for the specified duration, it sends a signal to unlatch the breaker mechanism.

Installation Requirements:
Ensure the trip unit is fully seated and locked into the circuit breaker frame. Verify that the current rating matches the protected equipment.

Usage Precautions:
Always use the manufacturer-approved test kit to verify trip functionality. Never bypass or modify the internal trip mechanisms.
