Siemens Sentron 5SY4 MCB, 2P, 10A Curve C, 400V AC, 10 kA Breaking Capacity

This miniature circuit breaker from Siemens is designed to protect your equipment from current surges. It works by cutting off power to the electrical circuits, preventing system damage through overloads. As it's a type C MCB, it trips if it detects between 5 and 10 times its rated current load. This makes it suitable for use in heavy-duty systems such as lighting fixtures and electric motors. It features toggle switches on its body so you can easily reset it. Thanks to its broad operating temperature range between -25°C and +55°C, you can rely on this device in demanding environments. The DIN rail mounting style lets you install it without the need for specialist tools.

• Can be mounted in any position for versatility
• Mechanical service life of 20,000 cycles for long-term use
• Resistant to shock and vibration to prevent false tripping

The breaking capacity is the maximum current that this MCB can disrupt in a system without sustaining any damage itself. This unit has a breaking capacity of 10kA.
