    AI Overview
    The 1MAS123 is a specific model of an AC contactor, often listed as an ABB component used for controlling electric motors or HVAC systems. 
    Based on general "Definite Purpose" contactors with similar specifications in the HVAC market, these devices commonly feature: 
    • 1-Pole or 3-Pole Construction: Often used for switching single-phase power in residential or light commercial AC units.
    • Coil Voltage: Usually 24VAC (common for HVAC controls).
    • Amperage: Commonly rated for 30A to 40A full-load.
    • Application: These are used as replacements in HVAC systems to turn the condenser/compressor on and off. 
    Replacement Notes
    If you are looking for a replacement for a 1MAS123, you can use any compatible "Definite Purpose" contactor with the same pole count, FLA (Full Load Amps), and coil voltage (usually 24V). 
    • Common replacements include 1-pole, 30 Amp or 40 Amp contactors with 24VAC coils.
    • Ensure the mounting base matches your existing unit for a drop-in replacement. 
    Note: The results indicate 1MAS123 is a specific part sometimes associated with ABB or related suppliers, so verifying the 24VAC coil and pole configuration is recommended before purchasing a replacement.
