SCHURTER 4430.2736 Thermal Circuit Breaker Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.2736 is a thermal circuit breaker rated for 240 V AC and 60 V DC operation with a 2-pole rocker actuator configuration designed for panel mount installation. This component is currently in active product status with 1097 units in stock. Thermal circuit breakers in this series provide overcurrent protection for industrial and commercial applications requiring dual voltage operation capability.

Substitute parts are necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from equivalent models within the same product series and electrical specification range.

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the primary part number 4430.2736 across the specified 240 V AC / 60 V DC operating range. Selection should prioritize active product status parts to ensure long-term availability and supply chain continuity.

Active status alternatives include 4430.1147, 4430.1158, 4430.2487, 4430.2781, 4430.2906, 4430.3172, 4430.3295, and 4430.3331. These parts carry ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Obsolete status parts (4430.0617, 4430.0764) remain electrically equivalent but should be considered only when existing inventory must be consumed or when design legacy requirements mandate their use. Obsolete parts carry REACH affected status, indicating potential future regulatory constraints.

Parts with documented approval agency certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077) include 4430.1147, 4430.2487, 4430.2781, and 4430.2906, providing additional assurance for applications requiring third-party validation.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for SCHURTER 4430.2736?

A: Substitution requires identical specifications across voltage rating (240 V AC / 60 V DC), breaker type (thermal), mounting configuration (panel mount), actuator type (rocker), pole count (2-pole), and series classification (TA45). All listed parts meet these criteria.

Q: Are obsolete parts suitable for new designs?

A: Obsolete parts (4430.0617, 4430.0764) are electrically equivalent but not recommended for new designs due to discontinued production status and potential future supply constraints. Active status parts ensure long-term component availability.

Q: What is the difference between REACH Unaffected and REACH Affected status?

A: REACH Unaffected parts comply with current EU chemical regulations with no anticipated future restrictions. REACH Affected parts may face regulatory changes requiring substitution in future procurement cycles. Active parts in this list carry REACH Unaffected status.

Q: Do all substitute parts have the same approval certifications?

A: No. Parts 4430.1147, 4430.2487, 4430.2781, and 4430.2906 carry documented approval agency certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077). Other parts maintain ROHS3 compliance without listed third-party certifications. Verify certification requirements for your specific application.

Q: Can I use these parts interchangeably in existing assemblies?

A: Yes. All substitute parts maintain identical electrical and mechanical specifications, including voltage ratings, mounting configuration, and actuator type. Direct substitution is supported without circuit or mechanical redesign.

Q: What inventory levels should I consider for procurement?

A: Current inventory ranges from 800 to 1180 units across active parts. 4430.3295 (1160 units), 4430.1147 (1180 units), and 4430.2487 (1151 units) offer the highest stock levels for immediate availability.
