Reliable Support for Circuit Breaker Auxiliary Releases
Electrical releases provide important remote-control and protection functions within a circuit breaker. The shunt opening release allows electrically commanded opening, the shunt closing release provides electrically commanded closing where the breaker mechanism permits it, and the under voltage release responds to an inadequate control supply.
The ABB 1SDA038339R1 provides the dedicated mechanical support for these YO, YC and YU release assemblies. As an original ABB spare component, it is suited to servicing compatible Emax and T8 breakers where the existing release support requires replacement or the appropriate support is needed as part of an auxiliary release assembly.
Typical Applications
- ABB SACE Emax circuit breaker maintenance and repair.
- Support for shunt opening release assemblies.
- Support for shunt closing release assemblies.
- Support for under voltage release assemblies.
- Industrial low-voltage switchboards and distribution panels.
- Replacement of damaged or missing auxiliary release supports.
- Compatible ABB Emax E1–E6 and Tmax T8 circuit breaker installations.
