C3SS1-30R-20

The ABB C3SS1‑30R‑20 is a compact 3‑position rotary selector switch designed for use in industrial control panels and automation systems. It features a short red handle for manual selection between three maintained positions (typically labeled A, B, and C), allowing operators to choose between different control modes or states. The unit is non‑illuminated and built for reliable performance in control logic applications requiring simple manual position selection.

Key Features Selector Type: 3‑position maintained rotary selector switch. Actuator: Short red handle for intuitive manual operation. Design: Non‑illuminated selector with a chrome metal bezel and robust construction. Function: Maintained — the switch stays in the selected position until changed by the operator. Compact Range: Space‑efficient design for standard control panels. Electrical Ratings Contact Configuration: 2 Normally Open (2 NO) auxiliary contacts for control circuit switching. Rated Operational Voltage: Up to 300 V AC/DC in typical control system environments. Rated Operational Current: Suitable for AC‑15 control duties (e.g., around 1 A at 220–240 V AC). Suitable for DC‑13 control duties at lower DC voltages. Rated Insulation Voltage: Designed for standard low‑voltage control circuits. Rated Impulse Withstand Voltage: Suitable withstand for transient events in normal use. Mechanical & Environmental Positions: Three fixed maintained positions (A, B, C). Mechanical Durability: Designed for a high number of operations in industrial settings. Operating Temperature Range: Suitable for typical industrial ambient conditions. Storage Temperature Range: Broader range for shipping and storage conditions. Protection: Good ingress protection at the front when correctly mounted; terminals protected when installed inside an enclosure. Physical & Installation Panel Cut‑out: Fits a standard 22 mm pilot device cut‑out. Bezel Material: Chrome metal for durability and panel aesthetics. Housing: Plastic body suitable for industrial environments. Terminals: Screw‑type terminals for secure wiring. Typical Applications Mode selection (e.g., Off/Auto/Manual) in industrial control panels. Operator interfaces for machinery and process control equipment. Control logic inputs for PLCs, relays, and contactor systems. Multi‑position manual selection for automation systems.
