Circuit Breaker Thermal 50mA 240VAC 32VDC SCHURTER 4435.0021

Part Overview

The SCHURTER 4435.0021 is an active thermal circuit breaker designed for panel mount applications. This single-pole rocker-actuated breaker provides overcurrent protection at 50mA with dual voltage ratings of 240V AC and 32V DC. The part is ROHS3 compliant and REACH unaffected, making it suitable for regulated industrial and commercial applications. Substitute parts may be required due to inventory availability, supply chain constraints, or project-specific sourcing requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4435.0021 is determined by strict equivalence across the following critical parameters:

• Current Rating: 50mA (exact match required)
• Voltage Rating - AC: 240V (exact match required)
• Voltage Rating - DC: 32V (exact match required)
• Breaker Type: Thermal (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Actuator Type: Rocker (exact match required)
• Number of Poles: 1 (exact match required)
• Series: TA35 (same product family)

Only parts meeting all these electrical and mechanical specifications are classified as parametric equivalents and may be substituted without circuit redesign or application re-evaluation.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 4435.0084 is a direct parametric equivalent to the 4435.0021. Both parts are active products from the same TA35 series with identical electrical ratings, mechanical configuration, and regulatory compliance status. Selection between these parts may be based on inventory availability, lead time, or procurement source preference. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the 4435.0084 be used as a direct replacement for the 4435.0021?

A: Yes. Both parts are parametric equivalents with identical current ratings (50mA), voltage ratings (240V AC / 32V DC), breaker type (thermal), mounting configuration (panel mount rocker), and pole count (1). No circuit modification is required.

Q: Are there any differences in compliance or certification between these parts?

A: No. Both parts carry identical RoHS3 compliance and REACH unaffected status. They are suitable for the same regulated applications.

Q: What determines if a part can substitute for the 4435.0021?

A: Substitution requires exact matching of current rating, AC/DC voltage ratings, breaker type, mounting type, actuator type, and pole count. Any deviation in these parameters disqualifies a part from direct substitution.

Q: Are both parts currently in active production?

A: Yes. Both the 4435.0021 and 4435.0084 maintain active product status with SCHURTER Inc.

Q: Does packaging affect substitution eligibility?

A: No. Both parts are supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.
