Key Parameters

Substitute Part Grouping Explanation

Substitution for the Weidmüller 9926272020 requires matching the following critical parameters:

• Breaker Type: Magnetic with hydraulic delay mechanism
• Current Rating: 20A
• Voltage Rating: 240V AC/DC
• Number of Poles: 2-pole configuration
• Actuator Type: Lever operation
• Mounting: DIN rail standard
• Certifications: Compliance with CE, CSA C22.2 No 235, UL1077, and VDE standards
• Regulatory Status: RoHS compliance required

No substitute parts have been provided in the input data. Equivalent alternatives must satisfy all parameters listed above to ensure functional and regulatory compatibility within the original application circuit.

Engineering Selection Recommendations

When sourcing replacements for the obsolete Weidmüller 9926272020, prioritize candidates that maintain identical electrical specifications (20A, 240V, 2-pole) and mechanical form factor (DIN rail lever-actuated). Verification of certification status is mandatory—replacement components must carry equivalent approvals under CE, CSA C22.2 No 235, UL1077, and VDE standards to ensure regulatory compliance in the target application. RoHS compliance is a non-negotiable requirement for new procurement.

Frequently Asked Questions (FAQ)

Q: What makes a circuit breaker a valid substitute for the 9926272020? A: A substitute must match the 20A current rating, 240V AC/DC voltage specification, 2-pole configuration, lever actuation, DIN rail mounting, and carry equivalent international certifications (CE, CSA C22.2 No 235, UL1077, VDE).

Q: Is the magnetic-hydraulic delay mechanism critical for substitution? A: Yes. The hydraulic delay characteristic is integral to the breaker's trip response profile. Substitutes must employ identical or functionally equivalent delay mechanisms.

Q: Can I use a single-pole breaker as a substitute? A: No. The 9926272020 is a 2-pole device. Single-pole alternatives do not provide equivalent circuit protection and are not compatible.

Q: What is the significance of the obsolete status? A: Obsolete status indicates the manufacturer no longer produces this part. Immediate identification and qualification of alternatives is necessary for supply chain continuity.

Q: Are RoHS and REACH compliance requirements for substitutes? A: RoHS compliance is mandatory for new component procurement. REACH unaffected status applies to the original part; substitute components must meet current regulatory requirements at the time of purchase.
