ABB SU201M-K50 Servo Motor

ABB SU201M-K50 miniature circuit breaker is a 1‑pole, 50 A UL489‑listed protective device with a 10 kA short-circuit breaking capacity (K‑characteristic). It is rated for 240 V AC at 50/60 Hz and designed for DIN‑rail mounting with screw-terminal connections that accept 18 AWG to 4 AWG copper conductors. The unit comes in an IP20 enclosure and is specified for ambient temperatures from −25°C to 55°C, making it suitable for standard panel installations in commercial and light industrial environments where reliable branch‑circuit protection is required. As part of ABB’s SU201M family (with related S201M‑K50 variants), this breaker provides conventional overcurrent protection for distribution boards and control panels, delivering predictable tripping behavior under overloads and short circuits in accordance with UL489.
