CKRB2430 Equivalent & Substitute Parts

Part Overview

The CKRB2430 is a Solid State Relay (SSR) manufactured by Sensata Technologies, configured as a SPST-NO (1 Form A) relay with integrated heat sink. This component is designed for applications requiring 30A switching capacity at input voltages between 24-280V. The part is currently in active inventory with 699 units available as new original stock.

Equivalent and substitute parts are identified based on matching electrical specifications including load current rating, output voltage range, circuit configuration, and thermal management design. Alternative models from Sensata-Crydom and Crouzet manufacturers provide functionally equivalent solutions for applications where the CKRB2430 may be unavailable or where specific mounting or input voltage requirements necessitate component substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CKRB2430 is determined by the following critical parameters:

• Load Current Rating: All substitutes must maintain the 30A switching capacity
• Circuit Configuration: SPST-NO (1 Form A) topology is required for functional equivalence
• Output Type: AC with Zero Cross switching capability
• Thermal Management: Integrated heat sink design for equivalent thermal performance
• Termination Style: Screw terminal connection for mechanical compatibility

The identified substitutes—DR2260A30U (Sensata-Crydom) and GNR30BCZH (Crouzet)—meet these core requirements while offering variations in input voltage ranges and mounting options suitable for different application environments.

Parameter Comparison

Engineering Selection Recommendations

DR2260A30U (Sensata-Crydom): This substitute maintains manufacturer continuity within the Sensata family and is classified as Active product status. The part supports both AC and DC input voltages (90-280VAC/DC) with extended load voltage capability (48-600V). RoHS compliance and DIN Rail mounting provide compatibility with modern industrial control systems. This option is suitable for applications requiring broader input voltage flexibility while maintaining the same 30A load current specification.

GNR30BCZH (Crouzet): This substitute is Active product status with RoHS compliance and REACH unaffected designation. The part offers dual mounting options (Chassis Mount and DIN Rail) and extended load voltage range (48-660V). Input voltage is limited to 80-140VAC, making this option suitable for standard AC-only applications. The module package type provides alternative form factor options for specific installation requirements.

Frequently Asked Questions (FAQ)

Q: Can DR2260A30U replace CKRB2430 in all applications? A: DR2260A30U is functionally equivalent for SPST-NO 30A switching applications. Verify that your input voltage requirement falls within the 90-280VAC/DC range and that DIN Rail mounting is compatible with your installation. The extended load voltage range (48-600V) provides broader application coverage than the CKRB2430 specification.

Q: What is the primary difference between DR2260A30U and GNR30BCZH? A: The primary differences are input voltage range and mounting options. DR2260A30U accepts 90-280VAC/DC input, while GNR30BCZH is limited to 80-140VAC. GNR30BCZH offers both Chassis Mount and DIN Rail options, whereas DR2260A30U is DIN Rail only. Load voltage ranges differ: DR2260A30U supports 48-600V and GNR30BCZH supports 48-660V.

Q: Is GNR30BCZH suitable for DC input applications? A: No. GNR30BCZH is specified for 80-140VAC input only and does not support DC input. For DC or mixed AC/DC input requirements, DR2260A30U is the appropriate substitute.

Q: Are all three parts RoHS compliant? A: DR2260A30U and GNR30BCZH are both RoHS Compliant. RoHS status for CKRB2430 is not specified in available documentation.

Q: What mounting flexibility do these substitutes provide? A: CKRB2430 mounting type is not specified. DR2260A30U supports DIN Rail mounting. GNR30BCZH supports both Chassis Mount and DIN Rail mounting, providing maximum installation flexibility.
