RP2203 25A 30MA 2P Earth Leakage Circuit Breaker

Part Overview

The RP2203 is a ground fault circuit breaker manufactured by Altech Corporation, rated for 25A at 230V AC/DC with a 2-pole configuration and lever actuator. This component is classified as obsolete, making identification of suitable alternatives necessary for ongoing maintenance and new installations where this model is no longer available through standard supply channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RP2203 is determined by the following critical parameters that must remain constant or compatible:

• Breaker Type: Ground Fault (functional requirement)
• Current Rating: 25A (load protection specification)
• Number of Poles: 2 (circuit configuration)
• Actuator Type: Lever (mechanical interface)
• Mounting Type: DIN Rail (physical installation requirement)
• Voltage Rating: Must support the system voltage where the breaker is installed

The substitute part 09124601 maintains compatibility across all functional and mechanical parameters. The primary difference is the voltage rating, which is 400V AC/DC instead of 230V. This part is suitable for substitution only in applications where the system voltage is 400V or where dual-voltage capability is required.

Parameter Comparison

Engineering Selection Recommendations

The RP2203 is obsolete and no longer in active production. Part 09124601 is the designated substitute from Altech Corporation and maintains active product status with current manufacturing support.

Selection between these parts is determined by system voltage requirements:

• For 230V AC/DC systems: The RP2203 is the original specification. If inventory is unavailable, 09124601 is not suitable for direct substitution due to voltage rating mismatch.
• For 400V AC/DC systems: Part 09124601 is the appropriate selection and is currently available.

Both parts carry CE and VDE certifications. The RP2203 additionally carries UL approval. Both are ROHS3 compliant. The substitute part 09124601 is available in active inventory (714 pcs), while the original RP2203 remains in stock (936 pcs) as new original components.

Frequently Asked Questions (FAQ)

Q: Can 09124601 be used in place of RP2203 in a 230V installation?

A: No. Part 09124601 is rated for 400V AC/DC. Using a 400V-rated breaker in a 230V system does not provide the correct protection characteristics for that voltage class.

Q: What is the primary difference between these two parts?

A: The voltage rating differs. RP2203 is rated for 230V, while 09124601 is rated for 400V. All other functional parameters—current rating, pole configuration, breaker type, and actuator mechanism—are identical.

Q: Are both parts DIN Rail mountable?

A: Yes. Both RP2203 and 09124601 are designed for DIN Rail mounting and share the same mechanical interface.

Q: What certifications apply to each part?

A: RP2203 carries CE, UL, and VDE approvals. Part 09124601 carries CE and VDE approvals. Both are ROHS3 compliant.

Q: Is 09124601 available for immediate use?

A: Yes. Part 09124601 is classified as active product status with 714 pcs in current inventory.
