Key Parameters

Substitute Part Grouping Explanation

Substitution of circuit breakers is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Parameters:

• Current Rating (Amps): Must match at 20A
• Voltage Rating - AC: Must match at 250V
• Voltage Rating - DC: Must match at 80V
• Breaker Type: Must be Magnetic (Hydraulic Delay) to maintain thermal delay characteristics

Mechanical Parameters:

• Number of Poles: Must be single-pole (1)
• Actuator Type: Must be Rocker for interface compatibility
• Mounting Type: Must be Panel Mount for installation compatibility
• Illumination: Must be None to match form factor

The substitute part IEGBX6-1-72-20.0-M6-V from Sensata-Airpax meets all these parameters and is therefore electrically and mechanically equivalent to the MA1-B-14-620-1-A16-2-J.

Parameter Comparison

Engineering Selection Recommendations
