CKRB6030 Equivalent & Substitute Parts

Part Overview

The CKRB6030 is a Solid State Relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (1 Form A) relay with integrated heat sink. This component is rated for 30A load current across a 48-660V operating range, designed for industrial switching applications requiring solid-state reliability without mechanical contacts.

Substitute parts are identified based on matching electrical specifications (voltage ratings, current capacity, circuit configuration) and mechanical compatibility (mounting type, termination style, package form factor). Alternative models become necessary when the primary part experiences supply constraints, regional availability limitations, or when system design requires components from alternative manufacturers within the same performance envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CKRB6030 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Load Current Rating: Must be rated for minimum 30 A continuous operation
• Load Voltage Range: Must encompass or exceed the 48-660V specification
• Output Type: Must support AC switching with zero-cross detection
• Termination Style: Must use screw terminal connections for direct wiring compatibility
• Package Form Factor: Must provide integrated heat sink or equivalent thermal management

The identified substitutes (DR2260A30U and GNR30BCZH) meet these criteria while originating from different manufacturers within the industrial SSR component ecosystem.

Parameter Comparison

Engineering Selection Recommendations

DR2260A30U (Sensata-Crydom): This substitute maintains manufacturer continuity within the Sensata-Crydom product line. It is designated as Active product status with RoHS compliance certification. The load voltage range is 48-600V, which covers standard industrial AC applications but does not extend to the full 660V upper limit of the CKRB6030. Selection of this part is appropriate when supply of the primary CKRB6030 is constrained and applications operate within the 600V maximum specification.

GNR30BCZH (Crouzet): This substitute provides cross-manufacturer compatibility with full voltage range equivalence (48-660V). It carries Active product status and RoHS compliance. The GNR30BCZH is rated for both Chassis Mount and DIN Rail mounting configurations, providing mechanical flexibility. This part is suitable for applications requiring the complete 660V load voltage specification or when Crouzet component qualification is required by system design standards.

Frequently Asked Questions (FAQ)

Q: Can DR2260A30U be used in applications requiring 660V load voltage?

A: No. The DR2260A30U is rated for maximum 600V load voltage. Applications requiring operation at 660V must use the CKRB6030 or GNR30BCZH.

Q: Are all three parts mechanically interchangeable?

A: All three parts use screw terminal connections and provide integrated heat sink packages. However, mounting configuration differences exist: the GNR30BCZH supports both Chassis Mount and DIN Rail mounting, while specific mounting details for CKRB6030 and DR2260A30U are not provided in the specification data. Verify mounting requirements against your system design before substitution.

Q: What is the significance of the zero-cross output type?

A: Zero-cross switching ensures the SSR activates only when the AC voltage waveform crosses zero, reducing electromagnetic interference and extending component life. All three parts support this feature, maintaining functional equivalence.

Q: Are there compliance differences between the substitutes?

A: Both DR2260A30U and GNR30BCZH carry RoHS Compliant certification and EAR99 ECCN classification. The GNR30BCZH additionally specifies REACH Unaffected status. Compliance requirements should be verified against your application and regional standards.

Q: What input voltage specifications apply to these parts?

A: The DR2260A30U accepts 90-280VAC/DC input. The GNR30BCZH accepts 80-140VAC input. Input voltage compatibility must be confirmed for your control circuit before substitution.
