ABB SD204/25 2CDD284101R0025 4P DIN Switch Disconnector 25 A 400V

The ABB SD204/25 (article 2CDD284101R0025) is a 4-pole switch disconnector rated at 25 A, designed to isolate electrical circuits safely and completely. By switching all four poles in a single operation, it covers three-phase-plus-neutral configurations and provides a clear isolation point for downstream equipment.

Technical specifications:

• Series: SD204/25
• ABB article number: 2CDD284101R0025
• EAN: 4016779904254
• Type: Switch disconnector
• Number of poles: 4P
• Rated current: 25 A

Features and benefits:

• 4-pole design switches all live conductors and neutral simultaneously, ensuring complete circuit isolation in one action
• 25 A current rating suits a broad range of small to medium distribution and load circuits
• Switch disconnector function combines on-load switching capability with a defined isolation position for safe maintenance work
• Four-pole configuration makes it directly applicable to three-phase plus neutral supply arrangements

Applications:

• Main or sub-circuit isolator in residential and commercial distribution boards
• Isolation of three-phase loads where the neutral conductor must also be switched
• Safe maintenance isolation point for machinery, equipment, and control panels
• Industrial and building installation sub-distribution where a compact 4-pole isolator is required
