Circuit Breaker Thermal 1180-02-5A Equivalent & Substitute Parts

Part Overview

The E-T-A 1180-02-5A is a thermal circuit breaker rated for 5A at 250V AC and 72V DC, featuring a push-push actuator in a single-pole holder configuration. This component is Active in product status and widely used in industrial control and protection applications. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for thermal circuit breakers in the 1180 series is determined by strict equivalence across electrical ratings and mechanical form factors. The following parameters must match or remain within acceptable tolerances:

• Current Rating: 5A (exact match required)
• Voltage Rating - AC: 250V (exact match required)
• Voltage Rating - DC: 72V (exact match required)
• Breaker Type: Thermal (exact match required)
• Actuator Type: Push-Push (exact match required)
• Number of Poles: 1 (exact match required)
• Mounting Type: Holder (exact match required)

Substitute parts are grouped into two categories: MFR Recommended (same manufacturer, alternative packaging) and Parametric Equivalent (different manufacturer, equivalent electrical and mechanical specifications).

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and meet international safety standards. The 1180-01-5A is the MFR Recommended substitute from E-T-A, differing only in packaging format (Box versus Bulk). This part carries identical electrical ratings, certifications, and mechanical specifications.

The 1279030000 from Weidmüller is a parametric equivalent that matches all critical electrical and mechanical parameters. It maintains compliance with CSA C22.2 No 235, UL1077, and VDE standards. Selection between E-T-A and Weidmüller variants depends on supply chain requirements, inventory availability, and certification scope alignment with system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1180-01-5A replace the 1180-02-5A in existing applications?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging: 1180-02-5A is supplied in Bulk, while 1180-01-5A is supplied in Box format. No circuit or mechanical modifications are required.

Q: Is the Weidmüller 1279030000 a direct substitute for the E-T-A 1180-02-5A?

A: The 1279030000 is a parametric equivalent. All electrical ratings (5A, 250V AC, 72V DC), mechanical form factor (push-push actuator, single-pole holder), and critical certifications (CSA C22.2 No 235, UL1077) are equivalent. It is suitable for applications where cross-manufacturer sourcing is acceptable.

Q: What certifications apply to all three parts?

A: All three parts meet CSA C22.2 No 235 and UL1077 standards. The E-T-A parts additionally carry CQC and IEC 60934 certifications. The Weidmüller part carries VDE certification. Verify certification requirements for your specific application before selection.

Q: Does packaging affect electrical or mechanical performance?

A: No. Packaging format (Bulk versus Box) affects only logistics and handling. Electrical specifications, mechanical dimensions, and performance characteristics remain identical.

Q: Are there inventory considerations when selecting a substitute?

A: Yes. Current inventory levels are: 1180-02-5A (960 Pcs), 1180-01-5A (834 Pcs), and 1279030000 (1125 Pcs). Availability may influence sourcing decisions based on project timelines.
