Curtis Industries CT-45 Equivalent & Substitute Parts Reference

Part Overview

Curtis Industries CT-45 is a barrier block terminal block designed for secure multi-circuit electrical connections. It features 45 circuits, a pitch of 0.546" (13.86mm), screw terminations, and is rated for 30A and 600V. The CT-45 is currently classified as obsolete, making identification of alternative models necessary for continued manufacturability, maintenance, and compatibility in new or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified strictly based on matching the critical electrical and mechanical parameters for barrier block terminal blocks. These include the number of circuits, pitch, current rating, voltage rating, wire gauge, termination type, barrier type, mounting type, operating temperature, insulation material, flammability rating, and compliance certifications. Only parts that align precisely with these fields are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute terminal block parts should align with product status, compliance standards, and provided certifications. The Curtis Industries CT-45 is obsolete, while the CDM-45 is active and maintains matching certifications such as RoHS, REACH, MSL rating, and UL94 V-0 flammability. Use CDM-45 where the same electrical and mechanical criteria are specified.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting Curtis Industries CT-45?
Substitution criteria include matching the number of circuits, terminal block type, pitch, current rating, voltage rating, wire gauge, termination type, barrier type, mounting type, insulation material, flammability rating, operating temperature, and certifications.

Q2: Are there differences in the mounting or termination between CT-45 and CDM-45?
Both CT-45 and CDM-45 feature chassis and panel mounting and use screw top terminations with closed bottom entries.

Q3: Does the substitute part CDM-45 have the same electrical ratings and size specifications?
CDM-45 matches CT-45 in current rating (30A), voltage rating (600V), number of circuits (45), pitch (0.546"), and wire gauge (10-22 AWG).

Q4: Are there any differences in compliance or certifications between CT-45 and CDM-45?
CDM-45 is ROHS3 compliant and REACH unaffected, consistent with CT-45. Both have a UL94 V-0 flammability rating and MSL of 1 (Unlimited).

Q5: Can CDM-45 be used in replacement applications for CT-45 in existing designs?
CDM-45 matches all specified parameters and certifications for replacement in applications where CT-45 is used.

Q6: What packaging is available for substitute parts?
Both CT-45 and CDM-45 are supplied in bulk packaging.
