Reliable Remote Circuit Breaker Closing
A shunt closing release provides an electrical means of operating a circuit breaker’s closing mechanism without requiring direct manual operation. When the specified control voltage is applied and the circuit breaker is in the correct operating condition, the release actuates the closing mechanism and enables remote or automated switching.
The ABB 1SDA038303R1 is designed for integration into low-voltage switchboards and control systems where circuit breaker closing commands may originate from control panels, automation equipment or supervisory systems. Its 240–250 V AC/DC rating makes it suitable for compatible AC and DC industrial control supplies.
Typical Applications
- Low-voltage switchboards and distribution panels.
- Remote circuit breaker closing systems.
- Industrial power distribution installations.
- Automated electrical switching systems.
- Process control and automation panels.
- ABB SACE Emax air circuit breaker installations.
- Compatible ABB SACE Tmax T8 circuit breaker installations.
