RP2403 63A 30MA 2P Earth Leakage Circuit Breaker

Part Overview

The RP2403 is a ground fault circuit breaker rated at 63A, 230V AC/DC with a 2-pole lever-actuated design for DIN rail mounting. This component is classified as obsolete, making equivalent substitutes necessary for ongoing system maintenance and new installations where the original part is no longer available through standard procurement channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the RP2403 is based on the following critical parameters that must remain consistent:

• Current Rating: 63A (primary load-carrying specification)
• Breaker Type: Ground Fault (functional classification)
• Number of Poles: 2 (circuit configuration)
• Mounting Type: DIN Rail (form factor requirement)
• Actuator Type: Lever (operational interface)

The substitute part 09144601 maintains these core parameters. However, the voltage rating differs: the substitute operates at 400V AC/DC versus the original 230V AC/DC specification. This voltage difference represents a key technical distinction that must be evaluated against system requirements.

Parameter Comparison

Engineering Selection Recommendations

The 09144601 substitute shares the same current rating, pole configuration, mounting standard, and breaker classification as the RP2403. Both components carry ROHS3 compliance and are manufactured by Altech Corporation, ensuring material and environmental consistency.

The primary distinction is voltage rating: 09144601 is rated for 400V systems compared to the original 230V specification. Selection between these parts depends on the actual system voltage requirement. The substitute part holds active product status, ensuring continued availability and supply chain reliability compared to the obsolete RP2403.

Both parts carry VDE certification. The original RP2403 includes additional CE and UL approvals; the substitute carries VDE approval only. Compliance requirements for your specific application must be verified against regional and industry standards.

Frequently Asked Questions (FAQ)

Q: Can the 09144601 directly replace the RP2403 in a 230V system?

A: The 09144601 is rated for 400V operation. Direct substitution in a 230V system requires confirmation that the component functions correctly at the lower voltage. The voltage rating represents the maximum operating specification.

Q: What are the key parameters that determine substitution eligibility?

A: Current rating (63A), breaker type (ground fault), pole count (2), mounting type (DIN rail), and actuator type (lever) must remain constant. Voltage rating differences must be evaluated against system requirements.

Q: Why is the RP2403 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 09144601 is an active product from the same manufacturer, providing continued availability for equivalent functionality.

Q: Are there compliance differences between these parts?

A: The RP2403 carries CE, UL, and VDE approvals. The 09144601 carries VDE approval. Application-specific compliance requirements must be verified before selection.

Q: What is the packaging difference?

A: The RP2403 is packaged as individual units; the 09144601 is supplied in bulk packaging. This affects procurement and inventory management but not functional compatibility.
