CTRC6025 Equivalent & Substitute Parts

Part Overview

The CTRC6025 is a 3-phase solid-state relay (SSR) manufactured by Sensata Technologies, rated for 25A load current at 48–600V AC output with zero-cross switching. Designed for chassis mount and DIN rail installation, this relay operates from 180–280VAC input and features screw terminal connections. The product is classified as Last Time Buy, indicating discontinued production. Identifying equivalent substitute parts is necessary to ensure continued availability and system reliability for applications requiring 3PST-NO (3 Form A) switching functionality.

Substitute Part Grouping Explanation

Substitute parts for the CTRC6025 are qualified based on the following critical parameters:

Circuit Configuration: Must be 3PST-NO (3 Form A) to maintain identical switching topology
Load Current Rating: Must be rated for 25 A minimum
Output Voltage Range: Must cover the 48–600 V AC operating window
Output Type: Must support AC switching with zero-cross functionality
Termination Style: Must use screw terminals for direct connection compatibility
Mounting Compatibility: Must support DIN Rail and/or Chassis Mount installation

The two qualified substitutes—DR6760A25P (Sensata-Crydom) and GNR25ACZH (Crouzet)—meet all mandatory electrical and mechanical criteria. Both are active products with current manufacturing status, providing long-term supply assurance compared to the CTRC6025's Last Time Buy status.

Engineering Selection Recommendations

DR6760A25P is the primary substitute for the CTRC6025. Both parts share the same manufacturer family (Sensata), identical load current and circuit configuration, and overlapping voltage specifications. The DR6760A25P features an integrated heat sink, which provides thermal management advantages in high-duty-cycle applications. Input voltage range extends to 90 VAC/DC, offering broader control signal compatibility. Active product status ensures long-term availability.

GNR25ACZH is a secondary substitute suitable for applications where DIN Rail mounting is the primary installation method. The Crouzet part extends output voltage capability to 660 V, accommodating higher-voltage load circuits. Input voltage range is narrower (24–255 VAC/DC), requiring verification that control signal levels are compatible with the application. ROHS3 compliance matches the original part. Active product status provides supply continuity.

Selection between DR6760A25P and GNR25ACZH depends on input voltage requirements and thermal management needs. Both parts satisfy the core electrical and mechanical substitution criteria for the CTRC6025.

Frequently Asked Questions (FAQ)

Q: Can DR6760A25P directly replace CTRC6025 in existing installations?

A: Yes. Both parts share identical circuit configuration (3PST-NO), load current rating (25 A), output voltage range (48–600 V), and termination style (screw terminal). The integrated heat sink on the DR6760A25P is a functional enhancement. Mounting compatibility is identical for DIN Rail applications; verify chassis mount space if applicable.

Q: What is the key difference between DR6760A25P and GNR25ACZH?

A: The primary differences are input voltage range and mounting options. DR6760A25P accepts 90–280 VAC/DC input and supports both chassis mount and DIN Rail. GNR25ACZH accepts 24–255 VAC/DC input and supports DIN Rail only. Output voltage capability differs slightly (600 V vs. 660 V). Select based on control signal voltage and installation method.

Q: Is the integrated heat sink on DR6760A25P required for operation?

A: The integrated heat sink is a design feature that enhances thermal dissipation in continuous-duty applications. It does not prevent operation in applications where the original CTRC6025 was used; it provides additional thermal margin.

Q: Are all three parts RoHS3 compliant?

A: CTRC6025 and GNR25ACZH are explicitly ROHS3 compliant. DR6760A25P RoHS status is not specified in available documentation. Verify compliance requirements with the manufacturer if RoHS certification is mandatory for your application.

Q: Can GNR25ACZH be used in chassis mount applications?

A: No. GNR25ACZH supports DIN Rail mounting only. If chassis mount capability is required, DR6760A25P is the appropriate substitute.

Q: What is the input voltage compatibility range for each part?

A: CTRC6025 requires 180–280 VAC. DR6760A25P accepts 90–280 VAC/DC, providing broader compatibility. GNR25ACZH accepts 24–255 VAC/DC. Verify that your control signal voltage falls within the selected part's input range.
