Circuit Breaker Thermal Magnetic 6A 250VAC 80VDC Weidmüller 7940102271

Part Overview

The Weidmüller 7940102271 is a thermal magnetic circuit breaker rated for 6A at 250V AC and 80V DC, designed for DIN rail mounting with push-to-reset actuation. This two-pole breaker is part of the CB4200 series and maintains active product status with full RoHS compliance and CSA/UL/VDE approvals. Alternative equivalent parts may be required due to supply constraints, regional availability, or procurement preferences while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by exact matching of the following critical parameters: current rating (6A), AC voltage rating (250V), DC voltage rating (80V), breaker type (thermal magnetic), mounting configuration (DIN rail), actuation method (push to reset), and pole count (2). The Phoenix Contact 5650136 meets all these requirements and is classified as a parametric equivalent. Both parts maintain active product status, RoHS compliance, and appropriate regulatory approvals for direct substitution in applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Weidmüller 7940102271 and Phoenix Contact 5650136 are suitable for applications requiring a 6A thermal magnetic circuit breaker with 250V AC and 80V DC ratings on DIN rail. Selection between these parts should be based on availability, lead time, and procurement channel preference. Both maintain active product status and full RoHS compliance. The Weidmüller part carries CSA C22.2 No 235, UL1077, and VDE approvals, while the Phoenix Contact part maintains equivalent regulatory standing. Inventory levels show 894 units available for the Weidmüller part and 748 units for the Phoenix Contact part.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 5650136 directly replace the Weidmüller 7940102271? A: Yes. Both parts share identical electrical ratings (6A, 250V AC, 80V DC), breaker type (thermal magnetic), mounting configuration (DIN rail), actuation method (push to reset), and pole count (2). They are parametric equivalents suitable for direct substitution.

Q: Are there any differences in regulatory approvals between these parts? A: Both parts maintain RoHS compliance and active product status. The Weidmüller part lists CSA C22.2 No 235, UL1077, and VDE approvals. Verify specific approval requirements for your application before selection.

Q: What determines if a circuit breaker can substitute for another? A: Substitution requires matching current rating, AC and DC voltage ratings, breaker type, mounting type, actuation method, and pole count. Any deviation in these parameters disqualifies a part as a direct equivalent.

Q: Are both parts available in the same packaging format? A: Yes. Both the Weidmüller 7940102271 and Phoenix Contact 5650136 are supplied in bulk packaging.

Q: Which part should I select based on availability? A: Selection should be based on your procurement requirements and lead time constraints. The Weidmüller part has 894 units in stock, while the Phoenix Contact part has 748 units available.
