Phoenix Contact 0912033 Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 0912033 is a 6A 24VDC automatic reset circuit breaker designed for DIN rail mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance and new designs. The automatic reset actuator type distinguishes this breaker's operational characteristics from lever-actuated variants. Substitute parts must maintain identical electrical ratings and mounting compatibility while potentially offering updated product status and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 0912033 is determined by the following critical parameters:

• Current Rating: 6A (exact match required)
• Voltage Rating - DC: 24V (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Number of Poles: 1 (exact match required)

The Phoenix Contact 2909908 satisfies all mandatory electrical and mechanical compatibility criteria. Both parts share identical current and voltage ratings, single-pole configuration, and DIN rail mounting. The primary distinction is the actuator type: the 0912033 features automatic reset functionality, while the 2909908 employs a lever actuator. This difference affects operational behavior but does not prevent functional substitution in applications where manual reset capability is acceptable or preferred.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2909908 is the identified substitute for the obsolete 0912033 based on matching electrical specifications and mechanical compatibility. The 2909908 offers the advantage of active product status, ensuring continued availability and support. Both parts comply with RoHS requirements, with the 2909908 meeting the more recent ROHS3 standard. The 2909908 is additionally REACH-affected, indicating compliance with current European chemical regulations.

The transition from automatic reset to lever actuation represents the primary operational difference. Applications requiring automatic reset functionality should evaluate whether manual reset capability meets system requirements. The solid-state breaker technology in the 2909908 provides an alternative to the unspecified breaker type in the 0912033.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2909908 directly replace the 0912033 in existing installations?

A: Electrical and mechanical compatibility is confirmed through matching 6A current rating, 24VDC voltage rating, single-pole configuration, and DIN rail mounting. The actuator type difference (automatic reset versus lever) must be evaluated against specific application requirements.

Q: What is the significance of the actuator type difference?

A: The 0912033 automatic reset actuator resets the breaker without manual intervention after a fault condition clears. The 2909908 lever actuator requires manual reset. System design must accommodate this operational difference.

Q: Does the solid-state breaker type in the 2909908 affect compatibility?

A: Solid-state technology represents an alternative implementation method for circuit protection. Both breaker types provide 6A protection at 24VDC and are compatible with DIN rail mounting. Application-specific requirements for response time or load characteristics should be considered.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The 2909908 meets ROHS3 and is REACH-affected, representing current regulatory compliance. The 0912033 meets RoHS requirements applicable at its design phase.

Q: What packaging is available for the substitute part?

A: The Phoenix Contact 2909908 is supplied in box packaging. The original 0912033 packaging specification was not provided in the technical data.
