Siemens SENTRON Miniature Circuit Breaker 3P, 400 V, 6–80 A
3-pole | 400 V AC | 6–80 A, B/C, 10 kA
Siemens SENTRON miniature circuit breakers for machinery and industrial equipment
The Siemens SENTRON miniature circuit breakers are designed for the protection of electrical circuits against overload and short circuit. The available three-pole variants are intended for 400 V AC electrical systems.
Choose the required circuit breaker according to the rated current, tripping characteristic and Siemens product number. Available variants cover rated currents from 6 A to 80 A with B or C tripping characteristics and a rated short-circuit breaking capacity of 10 kA according to EN 60898.
Key features:
- Three-pole design (3P)
- Rated voltage: 400 V AC
- Rated current: 6–80 A depending on variant
- Tripping characteristic B or C depending on variant
- Rated short-circuit breaking capacity 10 kA according to EN 60898
- Touch protection
- Suitable for machinery and industrial applications
Select the replacement circuit breaker according to the electrical parameters and the original Siemens product designation.
Available variants
The circuit breakers are available in several rated-current versions. Most variants have a C tripping characteristic; the Siemens 5SY4363-6 63 A version has a B characteristic.
