1SDA050846R1 ABB Safety Shutters 4-Pole Full-Size Neutral E6H

Why Choose the ABB 1SDA050846R1 Safety Shutters?

The ABB 1SDA050846R1 is a genuine ABB safety shutter set for the fixed part of a withdrawable circuit breaker, designed for compatible ABB New Emax E6 installations. The assembly is specifically configured for 4-pole full-size neutral E6H circuit breakers and forms part of the protective equipment used within the breaker fixed portion.

Safety shutters provide an important physical barrier within withdrawable circuit-breaker systems. When the moving part of the breaker is withdrawn, the shutters cover the fixed-part primary contacts, helping prevent unintended access to the contact area and supporting safer inspection and maintenance procedures.

The 1SDA050846R1 is designed for E6H 4-pole full-size neutral (4p/f) configurations and is used with the withdrawable fixed part. Its application-specific design ensures correct mechanical integration with the corresponding ABB New Emax E6 circuit-breaker system.

Protective Shuttering for Withdrawable Circuit Breakers

Withdrawable air circuit breakers use a moving breaker assembly that connects to primary contacts in a permanently installed fixed part. Safety shutters are used to cover these fixed contacts when the breaker is removed or withdrawn, reducing the possibility of unintended contact with the primary connection area.

The ABB 1SDA050846R1 is specifically matched to the E6H 4-pole full-size neutral fixed-part arrangement. It is therefore suitable for maintenance, repair or replacement work where the correct ABB safety shutter assembly is required for an existing New Emax installation.

Typical Applications

• ABB New Emax E6H air circuit-breaker installations.
• 4-pole full-size neutral breaker configurations.
• Withdrawable circuit-breaker fixed parts.
• Low-voltage switchboards and distribution assemblies.
• Industrial power distribution systems.
• Circuit-breaker maintenance and refurbishment.
• Replacement of damaged or worn fixed-part safety shutters.
