ABB SU200 M SU200 M Miniature Circuit Breaker, 1-Pole, 16A, Type C, 277V ac AC, 48 V dc DC, 15 kA Breaking Capacity

This miniature circuit breaker provides overcurrent protection for single-pole electrical circuits and is designed for DIN-rail mounting in residential and commercial installations. It operates with Type C tripping characteristics and accommodates both AC and DC systems, offering Compact protection where space is limited. The device is compatible with standard panel assemblies and has Terminal connections suited to common wiring practices.

• 15kA breaking capacity reduces fault propagation risk
• 48V DC rated voltage supports low-voltage DC circuits
• Type C trip curve handles moderate inrush currents
• Double-clamp terminals simplify secure conductor connection
• Toggle reset actuator allows quick manual reset

• Suitable for protecting lighting and socket circuits
• Ideal for distribution boards in small commercial sites
• Used with DC control systems up to rated voltage
• Can be used for single-phase circuit protection on a DIN rail
• Appropriate for retrofit projects needing slim breakers

It is fitted onto a DIN rail for straightforward panel installation.

The manual toggle allows reset once the fault condition has been cleared and the device has cooled.

The enclosure meets IP20 protection for live parts and IP40 for mechanical access.

Conformance includes CSA 22.2 No.5, IEC/EN 60947-2, and UL 489.

It is a single-pole device with double-clamp terminals for conductor retention.
