Circuit Breaker Thermal Magnetic 1A 250VAC 80VDC Weidmüller 7940116409

Part Overview

The Weidmüller 7940116409 is a thermal magnetic circuit breaker rated for 1A 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 regulatory compliance. Alternative equivalent parts may be required due to inventory constraints, supply chain considerations, or specific application requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 7940116409 is determined by strict equivalence across the following critical parameters: current rating (1A), AC voltage rating (250V), DC voltage rating (80V), breaker type (thermal magnetic), number of poles (2), mounting configuration (DIN rail), and actuator mechanism (push to reset). Parts meeting all these specifications within the CB4200 series are classified as parametric equivalents. The substitute part 7940102280 satisfies all substitution criteria and maintains identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the primary part 7940116409 and substitute part 7940102280 are active products with identical regulatory certifications including CSA C22.2 No 235, UL1077, and VDE approval. Both parts maintain RoHS compliance and REACH unaffected status. Selection between these parts may be based on inventory availability, lead time, or procurement source, as they are electrically and mechanically interchangeable for all applications requiring a 1A thermal magnetic circuit breaker at 250V AC / 80V DC with DIN rail mounting and push-to-reset operation.
