ABB SU202M-K30 Safety Relay Module 24V DC DIN Rail

ABB SU202M-K30 is a two-pole miniature circuit breaker (MCCB) designed for DIN-rail mounting in industrial control panels. It provides overcurrent protection for circuits up to 30 A, with a Type K (K-curve) thermal-magnetic trip and a 10 kA interrupt capacity, certified under UL 489. The device supports DC operation with a maximum rated voltage up to 96 V DC, making it suitable for 24 VDC control circuits in automation and machinery applications. Its compact form fits on a TH35-15 (35 mm) DIN rail and measures about 69 mm in length, 35 mm in width, and 111 mm in height. This 2-pole unit is intended for coordinated protection across two conductors in DC distribution and control circuits, providing reliable, code-compliant protection in industrial environments.
