Description
GE AMC3GM
Technical Specifications
- Module Type: AMC3JK compatible circuit breaker module.
- System Compatibility: Designed for three-phase panelboards and switchboards.
- Bus Clip Configuration: Supports phase balancing configurations (A & B, B & C, A & C).
- Fastener Torque: Rail latch screws tightened to 25 in-lb; bus clip screws tightened to 27–32 in-lb.
Functional Features
- Phase Balancing: Allows repositioning of bus clips to ensure balanced panelboard loads in three-phase systems.
- Secure Mounting: Features a rail latch mechanism that pivots onto bus bars and engages securely.
- Modular Design: Enables easy installation, replacement, and maintenance within the panelboard framework.
Application Scenarios
Widely utilized in industrial manufacturing facilities, commercial buildings, and infrastructure power distribution networks requiring robust and reliable circuit protection.
Performance Parameters
- Mechanical Reliability: Engineered to withstand high mechanical stress during installation and operation.
- Thermal Performance: Designed to handle continuous load currents without exceeding thermal limits.
Material Composition
Constructed with high-grade conductive metals for bus connections and high-strength, flame-retardant thermoplastics for the module housing to ensure electrical insulation and fire safety.
Structural Characteristics
Features a compact, modular form factor with integrated guide fingers for precise alignment with panelboard interior rails. Includes adjustable rail latches and bus clip mounting points.
Operating Principle
The module acts as a mechanical and electrical interface between the circuit breaker and the panelboard’s bus bars. It routes electrical current through the breaker while providing a secure, low-resistance connection point that can be mechanically locked into place.
Installation Requirements
Power must be turned OFF before installation. Loosen latch lock screws, retract rail latches, align guide fingers with panelboard notches, and tighten rail latch screws to exactly 25 in-lb. For phase balancing, reposition the bus clip and tighten screws to 27–32 in-lb.
Usage Precautions
Never work inside the equipment without verifying power is OFF. Do not remove circuit protective devices until power is isolated. Strict adherence to torque specifications is required to prevent overheating or mechanical failure.
