Reliable Remote Opening for Circuit Breaker Systems
A shunt opening release provides an electrical means of opening a circuit breaker when its control coil receives the specified voltage. This allows the breaker to be operated remotely by control switches, relays, automation equipment or other suitable protection and control devices rather than relying solely on local mechanical operation.
The ABB YO accessory is designed specifically for compatible breaker platforms, helping engineers integrate remote opening functionality into low-voltage distribution and control systems. With its 60 V AC/DC rating and compatibility across the Emax 2 E1.2–E6.2 range, the 1SDA073671R1 provides a practical solution for switchboard and automation applications.
Typical Applications
- ABB Emax 2 air circuit breaker installations.
- Remote circuit breaker opening and trip circuits.
- Industrial low-voltage switchboards.
- Power distribution and protection systems.
- Automated electrical distribution equipment.
- Industrial control and emergency opening circuits.
