MCB SLS Selective overcurrent circuit breaker 3P Cs 50A TS35 HTN350C

Selective overcurrent switches – protection and reliability of the installation

This three-pole selective overcurrent switch, with a rated current of 50A and a Cs characteristic, is a key element in protecting the electrical installation. Designed by Hager, it provides effective protection against overloads and short circuits, minimizing the risk of failures and fires. The selectivity of the switch means that in the event of a short circuit, the one closest to the source of the problem will trip, while the remaining circuits remain energized – which is particularly important in complex installations.

Characteristics and application

The switch with a Cs characteristic combines the features of characteristics C and D. This means that it reacts faster to overloads than a type C switch, but is more resistant to surge currents than a type D switch. This makes it ideal for protecting circuits with receivers generating high starting currents, such as electric motors or heating devices. Mounting is on a DIN rail, which ensures easy installation and integration with the existing distribution board. The rated switching capacity of 25kA guarantees safety even in the event of serious disturbances in the network.

Key features and benefits

• Selectivity: Ensures continuity of power supply in the remaining circuits in the event of a failure of one of them – reduces downtime and facilitates problem location.
• Cs characteristic: Optimal protection for receivers generating high starting currents, such as motors or heaters. Prevents the switch from tripping unnecessarily when starting devices.
• High switching capacity (25kA): Guarantees safety even with high short-circuit currents – protects the installation from serious damage.
• DIN rail mounting: Quick and easy mounting in standard electrical distribution boards – saves time and installation costs.
• Protection degree IP20: Protection against accidental contact – increases safety of use.
• Rated voltage 400V and rated impulse withstand voltage 6kV: Ensures safe operation in typical electrical installation conditions.
• Overvoltage category IV: Suitable for use in most residential and commercial buildings.

This switch is a reliable solution for both professional installers and end-users looking for effective protection of their electrical installation. Its solid construction and compliance with standards ensure long-term and safe operation.
