5SY6303-7
The Siemens SENTRON 5SY6 series three-pole miniature circuit breaker features a C-characteristic curve, a rated current of 3A, a rated voltage of 230/400V AC, a short-circuit breaking capacity of 6kA, and is designed for quick-release mounting on a 35mm DIN rail. It is suitable for small-capacity control circuit protection.
Product Positioning
The SENTRON 5SY6303-7 is a Siemens 5SY6 series three-pole C-characteristic miniature circuit breaker with a rated current of 3A, designed to provide overload and short-circuit protection for small-capacity control circuits and auxiliary circuits.
Core Product Advantages and Features
Three-pole synchronous protection
The three-pole simultaneous disconnection design can simultaneously disconnect three phases or multiple lines, avoiding circuit imbalance caused by single-pole malfunction.
C-type bounce characteristics
It adopts a C-characteristic trip curve, which takes into account both overload protection for general loads and the ability to withstand line surge currents.
6kA short circuit breaking capacity
With a rated short-circuit breaking capacity of 6kA (according to EN 60898-1), it can effectively isolate fault current and ensure the safety of downstream equipment.
DIN rail quick installation
It adopts 35mm DIN rail snap-fit installation, requiring only 18mm width per pole, making the configuration and maintenance of the distribution box convenient.
