Key Features
Selector Type: 3‑position maintained rotary switch — stays in the selected position until manually changed.
Actuator: Short red handle for clear manual selection and easy operation.
Illumination: Non‑illuminated — no built‑in lamp or LED.
Compact Construction: Space‑efficient design tailored for panel mounting.
Durability: Suitable for industrial environments, designed for frequent use.
Contact Configuration: Two normally open (2NO) auxiliary contacts — useful for switching control circuits.
Electrical Ratings
Rated Operational Voltage: Suitable for low‑voltage AC/DC control circuits (up to ~300 V).
Rated Operational Current:
AC‑15 control duty currents typical for operator devices (e.g., ~1 A at ~220–240 V AC; higher at lower voltages).
DC‑13 duty capability at lower DC voltages (e.g., ~0.2–0.3 A at 24–125 V DC).
Insulation & Impulse Withstand: Designed with appropriate insulation and transient withstand levels for control‑circuit switching.
Mechanical & Environmental
Positions: 3 fixed positions with maintained action (no spring return from main positions).
Mechanical Durability: Designed for a high number of operations (hundreds of thousands).
Operating Temperature Range: Typical industrial ambient temperatures (approx. –25 °C to +70 °C).
Storage Temperature Range: Broader temperature range for transport and storage.
Protection:
Front: High ingress protection (dust and water resistance) when mounted properly.
Terminals: Basic touch protection at terminals when installed in an enclosure.
Physical & Installation
Panel Cut‑out: Standard 22 mm diameter hole for pilot devices.
Body / Bezel: Durable plastic body and bezel for panel mounting.
Terminal Type: Screw‑type terminals for secure wiring connections.
Compact Size: Slim profile for efficient space usage in control cabinets.
Typical Applications
Mode selection (e.g., Off/Auto/Manual) in machine control panels.
Control logic inputs for PLCs, relays, and contactors.
Industrial automation systems needing discrete manual position selection.
Operator interfaces in production equipment.
The ABB C3SS3‑10R‑20 is a compact 3‑position rotary selector switch designed for industrial control panels and automation systems. It provides a manual control interface with a short red handle, allowing a user to select between three discrete positions for functions such as mode selection (e.g., Off/Auto/Manual). The compact design makes it suitable for installation in space‑limited control panels.
