ABB Auxiliary Contact, 690V AC Rated Insulation Voltage, 6kV Rated Impulse Withstand Voltage - CAL4-11 Series - 1SBN010120R1011 CAL4-11 Want to ensure your switching equipment operates reliably? Fit this ABB auxiliary contact. It's built for passing data from the circuit to a logic controller, which in turn instructs a linked device, like a relay, to switch on or off. The unit is tough enough to handle a high-power setup, thanks to its 600V DC and 690V AC contact voltage rating. You can use it as a stand-alone hardware control unit too, so it's a versatile option. Features & Benefits • Small size of 60 (L) x 12 (W) x 69.4mm (H) fits into confined spaces without issue
• Tough plastic casing is touch-proof to prevent electric shocks
• Clearly marked NO and NC contact points simplify installation and operation
• Wide operating temperature range between -40°C and +70°C for use in challenging conditions Applications • Automated industrial processes
• Medical equipment
• Commercial network installations How durable is this contact? This auxiliary contact has a mechanical durability of 10 million operating cycles and a maximum switching frequency of 3,600 cycles per hour, so it's built to last the distance and won't wear out easily.
