ABB 2CDD284101R0050 ABB SD204/50 Switch Disconnector 4P

The ABB SD204/50 (article 2CDD284101R0050) is a 4-pole switch disconnector rated at 50 A, designed to switch and isolate circuits in a single operation. It disconnects all four poles simultaneously, providing complete electrical isolation across three-phase and neutral conductors. This makes it a practical choice wherever safe, full-circuit isolation is required during normal operation or maintenance.

Technical specifications:

• Series: SD204/50
• ABB article number: 2CDD284101R0050
• EAN: 4016779904285
• Type: Switch Disconnector
• Number of poles: 4P
• Rated current: 50 A

Features and benefits:

• 4-pole design disconnects all circuit conductors simultaneously, delivering complete electrical isolation in one action
• 50 A current rating covers medium-load three-phase distribution circuits
• Switch disconnector function combines switching and isolation in one device, reducing the number of components needed in a panel
• 4-pole configuration suits three-phase plus neutral installations where all conductors must be isolated together

Applications:

• Main or sub-main isolator in industrial and commercial distribution boards
• Isolation of three-phase loads such as motors, heaters, and machinery prior to maintenance
• Load switching in power distribution panels requiring 4-pole isolation
• Circuit isolation for safe inspection and service operations in industrial installations
