Substitute Part Grouping Explanation

Substitute parts for the MM1-B-34-615-1-3EB-B-C are identified based on strict equivalence of the following electrical and mechanical parameters:

• Breaker Type: Magnetic (Hydraulic Delay) protection mechanism
• Current Rating: 15A nominal capacity
• Voltage Ratings: 250 V AC and 80 V DC operational range
• Mounting Configuration: Panel mount form factor
• Actuator Interface: Lever-type manual operation
• Pole Configuration: Single-pole design
• Illumination Status: Non-illuminated

Parts meeting all these criteria are classified as parametric equivalents and may be substituted in applications where the original part number is unavailable or where supply chain requirements necessitate alternative sourcing.
