Siemens circuit breaker Safety and reliability

The Siemens 50 A 3-pole magnetothermal circuit breaker offers robust and efficient protection for three-phase distribution systems. Designed for industrial and tertiary environments, this device from the SENTRON line is distinguished by reliability, ease of installation and high performance even under severe conditions.

C curve and 6 kA breaking capacity

With a C-curve tripping curve, this circuit breaker can withstand inrush currents up to 5-10 times the rated current, making it ideal for circuits with slightly inductive loads, such as motors or transformers. The breaking capacity of 6 kA ensures effective protection against short circuits even in systems with high fault energy.

Compatibility and versatility

Operating up to 440V three-phase AC and 62.5V DC per pole, this circuit breaker is compatible with a wide range of applications. It is designed for systems up to overvoltage category III, with pollution degree 2, making it suitable even for non-residential technical environments.

Compact design and durable materials

3 Modules, easily integrated into standard electrical panels. It is halogen-free and silicone-free, making it suitable even in settings where higher safety standards are required in case of fire. In addition, the structure is plumbable, increasing the level of security against tampering.

Simple and safe installation

Screw terminals allow the connection of rigid, flexible and multiwire conductors up to 25 sq. mm² with a tightening torque between 2.5 and 3 Nm. This ensures a stable and secure connection. The IP20 (when conductors are connected) rating protects against accidental contact, enhancing safety during use.

Application fields

Siemens circuit breaker is ideal for:

  • Electrical distribution in industrial environments

  • Tertiary and commercial installations

  • Protection of three-phase lines and subsystems

  • Machinery and control panels

  • Applications where high selectivity and short-circuit protection are needed
