SU1D2AC Equivalent & Substitute Parts

Part Overview

The SU1D2AC is a single-pole circuit breaker with D-curve characteristic and 2A current rating, manufactured by Weidmüller. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component procurement.

The primary reason for identifying substitute parts is the discontinuation of the SU1D2AC from active production. Organizations maintaining systems with this component require compatible alternatives that preserve electrical and mechanical compatibility within existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SU1D2AC is determined by the following critical parameters:

• Current Rating: 2A (must match exactly)
• Number of Poles: 1P (single-pole configuration)
• Breaker Type: Thermal Magnetic with D-curve characteristic
• Mounting Interface: DIN Rail compatibility
• Voltage Ratings: AC and DC voltage compatibility with original application
• Regulatory Compliance: Certifications and standards alignment

The substitute part 2480760000 satisfies these criteria through identical current rating, pole configuration, thermal-magnetic operation with D-curve characteristic, and DIN Rail mounting. Both components are manufactured by Weidmüller, ensuring design consistency and mechanical interchangeability.
