GB2CD20 Equivalent & Substitute Parts

Part Overview

The GB2CD20 is a single-pole thermal magnetic circuit breaker manufactured by Schneider Electric, rated for 12A at 277V AC and 48V DC. This DIN rail-mounted breaker features toggle actuation and is designed for industrial control and distribution applications. The product maintains active status with full compliance to international safety standards including UL1077, CSA C22.2 No 235, and IEC 60947 series specifications. Equivalent substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part number becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitute parts for the GB2CD20 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution criteria are limited to the following parameters:

• Current Rating: 12A (exact match required)
• Voltage Rating - AC: 277V (exact match required)
• Voltage Rating - DC: 48V (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Actuator Type: Toggle (exact match required)
• Number of Poles: 1 (exact match required)
• Approval Agencies: Compliance with CSA C22.2 No 235, EN 60947-1, EN 60947-2, IEC 60947-1, IEC 60947-2, UL1077 (required)

Only parts meeting all of these criteria are classified as parametric equivalents. No deviations in electrical ratings, mechanical configuration, or regulatory compliance are permitted for substitution.

Parameter Comparison

Engineering Selection Recommendations

The GB2CB20 is a direct parametric equivalent to the GB2CD20. Both parts are manufactured by Schneider Electric and share identical electrical ratings, mechanical configuration, and regulatory compliance certifications. Selection between these two part numbers is based on availability and inventory status rather than technical performance differences.

Both parts maintain active product status and comply with all specified approval agencies: CSA C22.2 No 235, EN 60947-1, EN 60947-2, IEC 60947-1, IEC 60947-2, and UL1077. The GB2CB20 carries additional RoHS3 compliance documentation and REACH unaffected status, which may be relevant for specific procurement requirements or end-use applications subject to environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can GB2CB20 be used as a direct replacement for GB2CD20?

A: Yes. The GB2CB20 meets all parametric equivalence criteria for the GB2CD20, including current rating (12A), voltage ratings (277V AC / 48V DC), breaker type (thermal magnetic), mounting configuration (DIN rail), actuator type (toggle), pole count (1), and regulatory compliance certifications.

Q: Are there any differences in physical dimensions or mounting between these parts?

A: No dimensional or mounting differences are specified in the provided technical parameters. Both parts are single-pole DIN rail-mounted circuit breakers with toggle actuation.

Q: What is the significance of RoHS3 compliance on the GB2CB20?

A: The GB2CB20 carries RoHS3 compliance documentation, indicating conformance to Directive 2011/65/EU as amended. This certification is relevant for applications subject to European environmental regulations or procurement specifications requiring RoHS compliance.

Q: Are both parts suitable for 277V AC and 48V DC applications?

A: Yes. Both GB2CD20 and GB2CB20 are rated for dual-voltage operation at 277V AC and 48V DC, making them suitable for mixed-voltage distribution systems and control circuits operating at either voltage level.

Q: What approval agencies certify these circuit breakers?

A: Both parts carry certification from CSA C22.2 No 235 (Canadian Standards Association), EN 60947-1 and EN 60947-2 (European standards), IEC 60947-1 and IEC 60947-2 (International Electrotechnical Commission standards), and UL1077 (Underwriters Laboratories).
