Federal Pacific CJJM36400G 400 Amp 3-Pole Magnetic Motor Circuit Protector

The Federal Pacific CJJM36400G is a robust 3-pole magnetic motor circuit protector designed for industrial applications requiring reliable motor protection against short circuits and overloads. Manufactured by Federal Pacific Electric (FPE), this device features adjustable magnetic trip settings for precise customization to motor inrush currents, ranging from low to high multipliers (typically 700-1300% of rated current). It is rated for 400 amps continuous current and up to 600 VAC, making it suitable for medium-voltage motor control centers, panelboards, and switchgear in manufacturing, mining, and commercial facilities. Key benefits include compact design for easy installation, high interrupting capacity for safety, and durability in harsh environments. Compared to similar products like those from Schneider Electric or Eaton, the CJJM36400G offers cost-effective performance with proven reliability, though FPE's historical issues with residential breakers may warrant caution— this industrial model is generally well-regarded. Drawbacks include limited availability of parts due to FPE's discontinued status and potential compatibility issues with modern systems. Applications span motor starters, conveyor systems, and HVAC equipment. Condition analysis from images shows it as used with visible wear, dust, and minor scratches, but no major damage; faceplate details confirm model CJJM36400G, 400A, 3-pole, 600VAC max, with adjustable dials and UL/CSA certifications.
