Parameter Comparison

Engineering Selection Recommendations

Both the CLB-353-11ANN-B-A and CLB-353-27E3N-W-A/35 are Active products with identical electrical specifications, mechanical form factors, and regulatory certifications. Selection between these parts is based on availability and packaging considerations rather than functional differences.

The CLB-353-27E3N-W-A/35 carries an additional Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling. Both parts maintain full compliance with CE, cUL, TUV, UL1077, and UL1500 standards and are ROHS3 compliant.

For applications requiring thermal circuit protection at 35A with 250V AC / 32V DC ratings in panel-mount configurations, either part provides equivalent performance and protection characteristics.

Frequently Asked Questions (FAQ)

Q: Can CLB-353-27E3N-W-A/35 be used as a direct replacement for CLB-353-11ANN-B-A?

A: Yes. Both parts are identical in current rating (35A), voltage ratings (250V AC / 32V DC), breaker type (thermal), mounting configuration (panel mount), actuator type (push to reset), and regulatory certifications. Direct substitution is supported without circuit modification.

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

A: Substitution is determined by equivalence in current rating, AC/DC voltage ratings, breaker type, mounting type, actuator type, number of poles, and regulatory approval agencies. All these parameters are identical between the main part and substitute.

Q: Are there differences in compliance or certifications between these parts?

A: Both parts carry identical certifications: CE, cUL, TUV, UL1077, and UL1500. Both are ROHS3 compliant and REACH unaffected. The CLB-353-27E3N-W-A/35 includes an MSL rating of 1 (Unlimited), which does not affect functional equivalence.

Q: What is the difference between the part numbers CLB-353-11ANN-B-A and CLB-353-27E3N-W-A/35?

A: The part numbers reflect different internal design variants or manufacturing configurations within the CLB series. Despite different part numbers, the electrical and mechanical specifications are identical, making them functionally equivalent for circuit protection applications.

Q: Are both parts currently available?

A: Both parts maintain Active product status. Inventory availability should be confirmed through current stock records, as availability may vary by distributor and time.
