CT-30 Equivalent & Substitute Parts

Part Overview

The CT-30 is a 30-circuit barrier block connector manufactured by Curtis Industries, designed for chassis and panel mounting applications. This terminal block features a 0.546" (13.86mm) pitch with dual-wall barrier construction and screw termination on the top side. The CT-30 is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and system upgrades where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

The CDM-30 qualifies as a direct substitute for the CT-30 based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Terminal block type: Barrier Block
• Number of circuits: 30
• Pitch: 0.546" (13.86mm)
• Number of rows: 2
• Current rating: 30A
• Voltage rating: 600V
• Wire gauge range: 10-22 AWG
• Top termination: Screws
• Bottom termination: Closed
• Barrier type: 2 Wall (Dual)
• Operating temperature: 130°C
• Insulation material: Polyester Thermoplastic
• Flammability rating: UL94 V-0
• Mounting type: Chassis, Panel

The CDM-30 maintains identical electrical performance and physical dimensions, enabling direct replacement in applications where the CT-30 was originally specified.

Parameter Comparison

Engineering Selection Recommendations

The CDM-30 is the appropriate substitute for the CT-30 in all applications where the original part is specified. The CDM-30 is currently in active production status, ensuring availability and supply chain continuity. Both parts maintain identical electrical ratings, mechanical dimensions, and termination characteristics.

The CDM-30 carries ROHS3 compliance, representing an updated regulatory status compared to the CT-30's RoHS compliance. Both parts maintain REACH Unaffected status and UL94 V-0 flammability certification. The transition from CT-30 to CDM-30 introduces no functional or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the CDM-30 be used as a direct replacement for the CT-30?

A: Yes. The CDM-30 matches all critical electrical and mechanical parameters of the CT-30, including circuit count, pitch, current rating, voltage rating, wire gauge compatibility, termination type, and operating temperature. Direct substitution is valid.

Q: What is the primary difference between the CT-30 and CDM-30?

A: The CT-30 is obsolete, while the CDM-30 is in active production. The CDM-30 carries updated ROHS3 compliance. All functional and electrical characteristics remain identical.

Q: Are there any compatibility concerns when substituting the CDM-30 for the CT-30?

A: No compatibility concerns exist. Both parts feature identical pitch (0.546"), circuit count (30), row configuration (2), and mounting interfaces (chassis and panel). Physical and electrical interchangeability is complete.

Q: What packaging is available for the CDM-30?

A: The CDM-30 is supplied in bulk packaging. The CT-30 packaging specification was not provided in the original documentation.

Q: Are both parts compliant with current regulatory standards?

A: Both parts maintain REACH Unaffected status and UL94 V-0 flammability certification. The CDM-30 carries ROHS3 compliance, representing current regulatory alignment.
