ABB SMISSLINE TP S400M Miniature Circuit Breaker, 2-Pole, 10A, Type K, 240V ac AC, 25 kA Breaking Capacity

This miniature circuit breaker provides overcurrent protection for low-voltage AC systems and is designed for installation where Compact two-pole protection is required. It operates on 240V AC supplies and uses a thermal Plus electromechanical trip arrangement to interrupt faults rapidly while allowing normal currents to flow. The unit meets recognised industry switching device standards and is intended for distribution boards and control panels where space efficiency and defined tripping behaviour are needed.

• 25kA breaking capacity offers effective fault interruption
• Type K tripping characteristic protects motor and inductive loads
• Electromechanical thermal tripping ensures coordinated overload response
• Screw terminals enable secure conductor connections
• Reset I/O actuator allows clear on/off status control

• Suitable for protecting small motor circuits and inductive loads
• Used with single-phase distribution to isolate two conductors
• Ideal for Compact consumer units in residential installations
• Can be used for control panel branch-circuit protection
• Used for retrofit upgrades where space is constrained

It is rated for 240V AC operation suitable for typical single-phase supplies.

The device isolates two poles, providing simultaneous interruption of both conductors.

The enclosure meets IP20, providing protection against solid objects larger than 12 mm but not against liquids.

Thermal elements respond to prolonged overloads while the electromechanical mechanism trips on higher instantaneous faults.

It is manufactured to meet IEC/EN 60947-2 requirements.
