Circuit Breaker Thermal Magnetic 4A 250VAC 80VDC Phoenix Contact 5650134

Part Overview

The Phoenix Contact 5650134 is a thermal magnetic circuit breaker rated for 4A at 250V AC and 80V DC, designed for DIN rail mounting with push-to-reset actuation. This two-pole breaker is part of the TMC42 series and maintains active product status with RoHS compliance. Alternative equivalent models are necessary to support supply chain flexibility, design redundancy, and regional availability requirements in industrial control and distribution applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5650134 is determined by strict equivalence across the following critical parameters:

• Current Rating: 4A (exact match required)
• Voltage Rating - AC: 250V (exact match required)
• Voltage Rating - DC: 80V (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Number of Poles: 2 (exact match required)
• Actuator Type: Push to Reset (exact match required)

The Weidmüller 7940102287 meets all substitution criteria as a parametric equivalent, sharing identical electrical ratings, mechanical configuration, and functional characteristics. Both components are active products with RoHS compliance and bulk packaging availability.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 5650134 and Weidmüller 7940102287 are suitable for direct substitution in applications requiring a 4A thermal magnetic circuit breaker with 250V AC and 80V DC ratings on DIN rail systems. Selection between these components should be based on:

• Inventory availability and lead time requirements
• Regional supplier relationships and logistics
• Compliance certifications required for the end application (Weidmüller 7940102287 carries CSA C22.2 No 235, UL1077, and VDE approvals)
• Cost and procurement terms

Both components maintain active product status and RoHS compliance, ensuring long-term supply viability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 7940102287 directly replace the Phoenix Contact 5650134 in existing installations?

A: Yes. Both components share identical electrical ratings (4A, 250V AC, 80V DC), thermal magnetic protection characteristics, two-pole configuration, push-to-reset actuation, and DIN rail mounting. Direct substitution is supported without circuit modification.

Q: What parameters must remain identical for substitution to be valid?

A: Current rating, AC voltage rating, DC voltage rating, breaker type, mounting type, number of poles, and actuator type must all match exactly. Any deviation in these parameters invalidates substitution eligibility.

Q: Are there differences in approval certifications between these two breakers?

A: The Weidmüller 7940102287 carries CSA C22.2 No 235, UL1077, and VDE certifications. Verify that the required certifications for your application are present on the selected component before procurement.

Q: Do both components come in the same packaging format?

A: Yes. Both the Phoenix Contact 5650134 and Weidmüller 7940102287 are supplied in bulk packaging, supporting standard procurement and inventory workflows.

Q: What is the difference between the TMC42 and CB4200 series designations?

A: These are manufacturer-specific series identifiers. The TMC42 is the Phoenix Contact series designation, while CB4200 is the Weidmüller series designation. Both series contain components with identical electrical and mechanical specifications for this 4A rating class.
