CKRA6030 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The CKRA6030 is a Solid State SPST-NO (1 Form A) relay manufactured by Sensata-Crydom, designed for AC load switching applications with integrated heat sink and DIN Rail mounting. This component operates with input voltage range of 90–280VAC and supports load voltages from 48V to 660V at 30A capacity with zero-cross switching capability.

The CKRA6030 is designated as Last Time Buy, indicating discontinued production. Equivalent substitute parts are available from active product lines to maintain system functionality and ensure continued component availability for new designs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CKRA6030 are qualified based on the following electrical and mechanical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Output Type: Must be AC with zero-cross switching for equivalent load control characteristics
• Load Current: Must be rated for 30A minimum
• Load Voltage Range: Must support the full 48V–660V range or equivalent upper limit
• Input Voltage Compatibility: Must accept 90–280VAC input or broader range
• Mounting and Termination: Must support DIN Rail mounting with screw terminal connections
• Regulatory Compliance: Must maintain RoHS compliance status

The following parts meet these substitution criteria:

1. DR2260A30U (Sensata-Crydom, Active) – Manufacturer-recommended substitute with identical electrical ratings and DIN Rail mounting
2. GNR30ACZH (Crouzet, Active) – Cross-manufacturer equivalent with matching load specifications and flexible mounting options

Parameter Comparison

Engineering Selection Recommendations

DR2260A30U is the primary substitute for CKRA6030 applications. Both components are manufactured by Sensata-Crydom, share identical electrical specifications for load current and input voltage, and maintain equivalent DIN Rail mounting and screw terminal interfaces. DR2260A30U is in active production status, ensuring long-term component availability. The load voltage range of DR2260A30U extends to 600V, which covers standard industrial AC applications; applications requiring the full 660V upper limit should be evaluated against specific load requirements.

GNR30ACZH provides an alternative cross-manufacturer substitute from Crouzet. This component maintains identical 30A load current and 48V–660V load voltage range specifications. GNR30ACZH supports both chassis mount and DIN Rail mounting configurations, offering installation flexibility. Input voltage range is 180–280VAC, which covers the upper portion of the CKRA6030 input specification; applications requiring operation below 180VAC input should use DR2260A30U instead. GNR30ACZH is in active production status with RoHS compliance certification.

Both substitute parts maintain zero-cross AC switching output type and SPST-NO circuit configuration, ensuring functional equivalence in load control applications.

Frequently Asked Questions (FAQ)

Q: Can DR2260A30U replace CKRA6030 in all applications?

A: DR2260A30U is electrically and mechanically equivalent for standard industrial AC switching applications. The load voltage range extends to 600V, which accommodates typical industrial loads. Applications requiring operation at the full 660V upper limit should be evaluated against specific load voltage requirements.

Q: What is the key difference between DR2260A30U and GNR30ACZH?

A: Both parts are functionally equivalent for 30A AC load switching. DR2260A30U accepts input voltage from 90–280VAC and 90–280VAC/DC, while GNR30ACZH operates from 180–280VAC input. DR2260A30U is recommended for applications requiring lower input voltage operation. GNR30ACZH offers flexible mounting (chassis mount or DIN Rail), while DR2260A30U is optimized for DIN Rail installation.

Q: Are all substitute parts RoHS compliant?

A: Yes. CKRA6030, DR2260A30U, and GNR30ACZH are all RoHS compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: Can GNR30ACZH be mounted in the same DIN Rail configuration as CKRA6030?

A: Yes. GNR30ACZH supports both chassis mount and DIN Rail mounting types, providing installation flexibility equivalent to or exceeding CKRA6030 mounting options.

Q: What is the significance of "Last Time Buy" status for CKRA6030?

A: Last Time Buy indicates that CKRA6030 production has been discontinued. Existing inventory may be available for a limited period. For new designs and long-term system support, DR2260A30U or GNR30ACZH are recommended as they are in active production status.

Q: Do the substitute parts use identical termination methods?

A: Yes. CKRA6030, DR2260A30U, and GNR30ACZH all use screw terminal connections, ensuring compatibility with existing wiring and installation practices.
