Product Description

Description

Engineered for seamless integration into legacy and specialized electrical distribution systems, the ABB S111-K10 functions as a high-reliability screw-in miniature circuit breaker. Designed to directly replace traditional screw-in fuse links, this device features a standard E27 thread base, enabling quick retrofitting without requiring complete panel upgrades. The unit incorporates a thermal-magnetic tripping mechanism to deliver precise overcurrent and short-circuit protection, combining the convenience of a modern, resettable circuit breaker with the physical form factor of legacy fuse systems.

By utilizing the K-tripping characteristic, the ABB S111-K10 is highly suited for safeguarding control circuits, auxiliary systems, and loads with moderate inrush currents. This device ensures minimized downtime through its immediate manual reset capability following a fault, eliminating the ongoing maintenance overhead and waste associated with disposable melt fuses.

Features

Direct screw-in installation utilizing a standard E27 thread base for rapid retrofitting.
Thermal-magnetic trip mechanism provides robust overcurrent and short-circuit protection.
Resettable design eliminates the requirement for replacement fuse links after tripping events.
K-characteristic curve optimized for sensitive equipment and circuits with transient inrush currents.
Clear mechanical status indication for straightforward operational diagnostics.

Applications

Modernization of legacy residential and commercial distribution panels.
Overcurrent protection in industrial control systems and auxiliary circuits.
Machinery control panels requiring compact, socket-mounted circuit protection.
Facility maintenance and retrofitting where panel space or configuration restricts DIN-rail mounting.

Installation Guidelines

Prior to installation, ensure the target electrical circuit is completely de-energized and locked out.
Inspect the existing E27 socket for dirt, corrosion, or damage before inserting the circuit breaker.
Thread the device into the socket manually, turning clockwise until firmly seated. Do not apply excessive torque to prevent cracking the socket casing.
Verify that the rated load of the branch circuit does not exceed the 10 A capacity of the device.
