Circuit Breaker Thermal Magnetic 32A Lever 0914725

Part Overview

The Phoenix Contact 0914725 is a thermal-magnetic circuit breaker rated for 32A with lever actuation, designed for DIN Rail mounting. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system maintenance and new designs. The substitute part maintains the core electrical and mechanical characteristics required for direct functional replacement.

Key Parameters

Substitute Part Grouping Explanation

The E-T-A 410-K-1-01-SI-32A qualifies as a functional substitute based on the following critical parameters:

• Current Rating Match: Both parts are rated for 32A operation
• Breaker Type Match: Both employ thermal-magnetic protection technology
• Actuator Type Match: Both feature lever actuation
• Pole Configuration Match: Both are single-pole devices
• Compliance Alignment: Both maintain RoHS compliance (Phoenix Contact RoHS Compliant; E-T-A ROHS3 Compliant)

The primary difference is mounting configuration: the original part uses DIN Rail mounting, while the substitute uses Chassis Mount. This distinction requires mechanical integration assessment during implementation.

Parameter Comparison

Engineering Selection Recommendations

The E-T-A 410-K-1-01-SI-32A is an active product with current manufacturing support and UL1077 certification, providing regulatory continuity for applications requiring third-party approval. The substitute maintains electrical equivalence at the 32A thermal-magnetic protection level with lever control. Mounting configuration differences necessitate mechanical redesign or adapter implementation. The substitute's specified voltage ratings (240V AC / 110V DC) provide defined operating parameters absent from the original part specification.

Frequently Asked Questions (FAQ)

Q: What makes the E-T-A 410-K-1-01-SI-32A a valid substitute for the Phoenix Contact 0914725?

A: Both parts share identical current ratings (32A), breaker technology (thermal-magnetic), actuation method (lever), pole configuration (single-pole), and RoHS compliance status. These parameters define functional equivalence for circuit protection applications.

Q: Does the mounting type difference affect substitution viability?

A: Mounting type is a mechanical integration parameter, not an electrical one. DIN Rail and Chassis Mount configurations require different physical installation approaches. System redesign or mechanical adaptation may be necessary depending on the application enclosure design.

Q: Are the voltage ratings of the E-T-A part applicable to the original application?

A: The E-T-A substitute specifies 240V AC and 110V DC ratings. The original Phoenix Contact part does not provide voltage specifications in available documentation. Verify that the application voltage requirements align with the substitute's ratings before implementation.

Q: What is the significance of the UL1077 certification on the substitute part?

A: UL1077 is a recognized safety standard for supplementary protectors. This certification indicates third-party validation of the E-T-A part's protective characteristics and may be required for applications subject to regulatory compliance frameworks.

Q: Can the substitute be used in new designs?

A: Yes. The E-T-A 410-K-1-01-SI-32A carries Active product status with current manufacturing availability, making it suitable for both replacement and new design applications. The Phoenix Contact original is obsolete and no longer manufactured.
