Parameter Specification Product Family Accessory for ABB Emax 2 (E2) Air Circuit Breakers & compatible MCCBs. Device Type Mechanically Operated, Cabled Auxiliary Contact Block Article Number 1SDA054910R1 Contact Configuration 1 NO (Normally Open) + 1 NC (Normally Closed) Form: 1 Changeover (SPDT) contact (logically derived from 1Q1SY). Contact Rating (Utilization Category) AC-15: 250V, 2.5 A DC-13: 250V, 0.2 A (Typical values for auxiliary contacts. Confirm from official sheet) Rated Operational Voltage (Ue) 250 V AC / 250 V DC Rated Thermal Current (Ith) 10 A Mechanical Life ≥ 10,000 operations (aligned with breaker mechanical endurance) Electrical Life ≥ 100,000 operations (at rated resistive load) Output Connection Pre-fitted flexible cables (Approx. 500mm length, specific color code). Cables are terminated with bare ends or pin terminals for connection to customer's terminal block. Cable Specification Typically multi-core, fine-strand control cable with insulation suitable for panel wiring. Mounting / Compatibility Direct mechanical mounting onto designated point on the Emax 2 breaker operating mechanism. The T4-6 code specifies exact compatibility (e.g., for breakers with rotary handle mechanisms of certain frame sizes). Operation Actuated directly by the breaker's moving parts. Contacts change state in sync with the main contacts. Standards Compliance IEC/EN 60947-5-1 (Auxiliary devices for circuit-breakers) Ambient Temperature -25°C to +70°C (Operation)
