The S803S-D16 is a 3-pole high-performance miniature circuit breaker designed for circuit protection in IEC-compliant systems. It operates with a rated current of 16 A and a voltage rating of 690 VAC. Featuring a D-trip characteristic, this breaker has a high interrupting capacity of 50 kA. The thermal-magnetic trip mechanism is specifically designed to accommodate higher in-rush currents, making it ideal for protecting inductive loads like motors and transformers during system start-up.
