C2SS2-30B-10

The ABB C2SS2-30B-10 is a classical design, two-pole (2P), flush-mounted rotary cam switch from ABB's C2SS series, often referred to as a "section switch" or "changeover switch". It is a robust, manually operated switch primarily designed for control circuit applications, such as mode selection (e.g., Hand-Off-Auto), motor control (Forward-Stop-Reverse), or circuit isolation.

Technical Parameters Parameter Specification Series / Product Type ABB C2SS Series / Flush-Mounting Rotary Cam Switch (Section Switch) Order Code C2SS2-30B-10 Number of Poles 2-Pole (2P) Rated Operational Current (Ie) 30 A (Resistive load, AC-21A / AC-22A category) Contact Configuration (Code B) Specific arrangement must be confirmed from catalog. Common for 2P: Two contacts that are either both NO or one NO and one NC, switching simultaneously. Switching Positions Typically 2 positions (ON-OFF) (as indicated by the "-10" suffix code). Rated Operational Voltage (Ue) 690V AC (maximum) Rated Insulation Voltage (Ui) 690V AC Utilization Category AC-21A: Switching of resistive loads (including moderate overload). AC-22A: Switching of mixed resistive and inductive loads. AC-3: For motor switching, the current rating is significantly derated (e.g., 30A AC-21A might be 7.5 HP / 5.5 kW at 400V AC for AC-3). Motor Rating (AC-3) Approximately 7.5 kW / 10 HP at 400V AC, 3-phase (for a 2-pole switch used in a reversing or star-delta scheme, this is illustrative; exact value depends on configuration). Mechanical Life Typically 500,000 to 1,000,000 operations. Electrical Life At rated current (AC-21A): Typically 100,000 operations. Mounting Panel Flush Mounting via a mounting nut from the front. Requires a round panel cutout (specific diameter, e.g., 30mm). Shaft Square shaft for attaching handles. Degree of Protection (IP Rating) Front side (with handle): IP65 (Dust-tight, protected against water jets). Behind panel: IP00. Terminal Connection Screw terminals. Ambient Temperature -25°C to +70°C (Operation) Standards Compliance IEC/EN 60947-1, IEC/EN 60947-5-1
