MA1-M-12-440-1-A16-2-J Circuit Breaker Equivalent & Substitute Parts

Part Overview

The MA1-M-12-440-1-A16-2-J is an active production circuit breaker manufactured by Carling Technologies. This magnetic hydraulic delay circuit breaker is designed for panel mount applications with a 4A current rating and dual voltage capability (250V AC / 80V DC). The rocker actuator provides manual control for overcurrent protection in industrial and commercial electrical systems.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across manufacturers, ensuring functional interchangeability while preserving circuit protection characteristics and installation compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MA1-M-12-440-1-A16-2-J is determined by strict equivalence across the following critical parameters:

• Breaker Type: Magnetic (Hydraulic Delay) operation must be identical
• Current Rating: 4A specification must be maintained
• Voltage Ratings: Both 250V AC and 80V DC ratings must be supported
• Mounting Configuration: Panel mount installation capability required
• Actuator Type: Rocker actuator interface must be present
• Pole Configuration: Single pole (1P) design required
• Illumination Status: Non-illuminated design required

The IEGBX6-1-61-4.00-M3-V manufactured by Sensata-Airpax meets all specified parameters and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the MA1-M-12-440-1-A16-2-J and IEGBX6-1-61-4.00-M3-V are active production components with current regulatory compliance status. Selection between these parts is based on the following factors:

Carling Technologies MA1-M-12-440-1-A16-2-J: Approved under CCC, TUV, and UL489A standards. ROHS3 compliant. REACH unaffected status. Suitable for applications requiring Carling-specific certifications or existing supply chain integration.

Sensata-Airpax IEGBX6-1-61-4.00-M3-V: Approved under CSA, TUV, and UL1077 standards. RoHS compliant with MSL 1 (Unlimited) rating. Suitable for applications requiring Sensata-Airpax certifications or where bulk packaging is preferred.

Both parts maintain identical electrical performance characteristics and panel mount mechanical compatibility. Certification differences reflect manufacturer-specific approval pathways rather than functional capability variations.

Frequently Asked Questions (FAQ)

Q: Can the IEGBX6-1-61-4.00-M3-V directly replace the MA1-M-12-440-1-A16-2-J in existing installations?

A: Yes. Both parts share identical electrical ratings (4A, 250V AC, 80V DC), breaker type (magnetic hydraulic delay), mounting configuration (panel mount), and actuator interface (rocker). Panel mount dimensions and electrical performance are equivalent.

Q: Are there differences in approval certifications between these parts?

A: Yes. The MA1-M-12-440-1-A16-2-J carries CCC, TUV, and UL489A approvals. The IEGBX6-1-61-4.00-M3-V carries CSA, TUV, and UL1077 approvals. Both include TUV certification. Application requirements may dictate which certification pathway is necessary.

Q: What is the significance of the packaging difference?

A: The MA1-M-12-440-1-A16-2-J is supplied in standard packaging, while the IEGBX6-1-61-4.00-M3-V is supplied in bulk packaging. This affects order quantities and storage considerations but does not impact electrical or mechanical performance.

Q: Do both parts have the same RoHS compliance status?

A: Both parts are RoHS compliant. The MA1-M-12-440-1-A16-2-J is ROHS3 compliant, and the IEGBX6-1-61-4.00-M3-V is RoHS compliant. Both meet current environmental regulations.

Q: Are there any differences in moisture sensitivity?

A: The IEGBX6-1-61-4.00-M3-V specifies MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The MA1-M-12-440-1-A16-2-J does not specify MSL rating in the provided data.

Q: Can these parts be used interchangeably in the same circuit?

A: Yes. Identical current ratings, voltage ratings, breaker type, and pole configuration ensure functional interchangeability in circuit protection applications.
