GE S420PUAAH1A – Technical Overview

The GE S420PUAAH1A is  a protective relay or control module from General Electric (GE), potentially part of the Multilin or Mark series for industrial protection and automation systems.

Key Features & Specifications

1. Product Type:

• Protective Relay (e.g., for motor/generator protection, feeder management, or grid automation).
• Control Module (possibly within GE’s Mark VIe or Multilin platform for industrial applications).

2. Model Number Breakdown:

• S420: Likely denotes the series (e.g., Multilin 420 or a Mark VIe variant).
• PUA: Possible interpretations:
  • P = Protection functions (e.g., overcurrent, voltage monitoring).
  • U = Communication interface (e.g., USB, Ethernet).
  • A = Amperage rating or auxiliary features.
• AH1A: May indicate:
  • A = Advanced capabilities (e.g., arc flash detection).
  • H1 = Hardware version or voltage class (e.g., 120V AC/DC).
  • A = Compliance certifications (UL, CE).

3. Typical Functions (If a Relay):

• Overcurrent/undervoltage protection.
• Motor/generator fault diagnostics.
• Communication protocols: Modbus, Ethernet, or IEC 61850.
• Real-time monitoring and self-testing.

4. Estimated Technical Specifications:

• Input Voltage: 24V DC or 100-240V AC.
• Operating Temperature: -20°C to +60°C (industrial-grade).
• Mounting: DIN rail or panel-mounted.
• Certifications: UL, IEC, IEEE (if applicable).
