The S803S-UCB20-R is a 1-pole High Performance Circuit breaker for DC application with B-characteristic, with ring tongue terminal and a rated current of 20 A. It is a current limiting device with a maximum breaking capacity of 50kA at 750V. It can be used for voltages up to 750V DC. It has two different tripping mechanisms, the thermal tripping mechanism for overload protection and the electromechanic tripping mechanism for short circuit protection. The S803S-UCB20-R complies with IEC/EN 60947-2 and allows the use for industrial applications. It has numerous of approvals, therefore it can be used worldwide. The extensive range of accessory makes the use of S803S-UCB20-R more comfortable. Due to the fast arc extinction of S803S-UCB20-R your application will be secured.
