Protect your electrical installation from overload and short-circuit currents with the Siemens 5SP33353 main line circuit breaker. This device automatically disconnects the circuit when a fault occurs, preventing damage to wiring and connected equipment.

Who is it for

Electricians and electrical planners who need a reliable protective device for residential and commercial distribution boards. The 5SP33353 is suitable for main line protection in single-phase systems up to 240/415 V AC.

Main features

• Tripping characteristic: B (magnetic trip 3-5 times rated current)
• Rated current: 63 A
• Number of poles: 1
• Rated voltage: 230/400 V AC
• Breaking capacity: 10 kA according to EN 60898-1
• Width: 1 module (18 mm)

Tips

Always verify the short-circuit current at the installation point does not exceed the breaking capacity of the breaker. For main line protection, ensure selectivity with downstream circuit breakers.
