ABB 1SAM201903R1003

The SK1-02 signaling contact is designed for use with manual motor starters, providing a clear indication of tripping events, whether due to short-circuit, overload, or electrical release. The device includes a prominent orange button that must be manually reset after a tripping incident. This signaling contact can be configured as normally open or normally closed.

With dimensions of 9 mm in width, 90 mm in height, and a depth of 78.5 mm, the SK1-02 is compact yet effective. It operates at a rated voltage of 690 V AC and 600 V DC, supporting various operational currents across different voltage levels, such as 6 A at 24 V AC and 3 A at 400 V AC. The electrical durability is rated for 100,000 cycles, providing reliable performance over time.

Mounting on the right side of the manual motor starter, this contact is suitable for models MS116, MS132, MO132, MS165, and MO165. The SK1-02 adheres to several standards, including IEC/EN 60947 and UL 508, ensuring compliance with industry regulations. It also accommodates a wide range of wire sizes, from flexible to rigid conductors, enhancing its versatility for various applications.

The environmental resilience of the SK1-02 allows for operation in temperatures ranging from -25 °C to +60 °C and storage conditions of -50 °C to +80 °C. Additionally, it meets RoHS requirements, ensuring it is compliant with EU directives.
