Why Choose the ABB 1SDA068801R1 E2–E6 Auxiliary Contact Set?
The ABB 1SDA068801R1 is a dedicated opening and closing auxiliary contact accessory designed for compatible ABB Emax E2–E6 air circuit breakers. The assembly provides 2 normally open (NO) and 2 normally closed (NC) auxiliary contacts, together with connections intended for compatible PR122 and PR123 electronic trip units.
Auxiliary contacts allow the operating state of an air circuit breaker to be communicated to external control, indication and automation circuits. This makes the 1SDA068801R1 useful in switchboards where breaker position or operating status needs to be monitored by PLCs, signalling equipment, interlocking circuits or supervisory systems.
Designed for DC control applications and identified by ABB order code 1SDA068801R1, this accessory provides a purpose-designed interface for compatible E2–E6 installations. Using the correct ABB auxiliary contact assembly helps maintain compatibility with the circuit breaker and its associated protection and control system.
