Siemens SENTRON 5SY5 MCB, 2P, 2A Curve C, 10 kA Breaking Capacity

This MCB is a two-pole miniature circuit breaker designed for optimal performance in electrical protection applications. Measuring 36mm in width and 76mm in depth, it offers a current rating of 2A and is suitable for both AC and DC voltages, rated at 400V AC and 440V DC. With its robust design, it achieves an impressive breaking capacity of 10 kA, making it an essential element for safeguarding electrical circuits.

• Delivers reliable protection with a type C tripping characteristic
• Quick mounting on DIN rail enables efficient installation
• Features screw terminal connections for secure conductor attachments
• Operates efficiently at a mechanical service life of 10,000 cycles
• Suitable for a wide voltage range including 400V AC
• Halogen-free design ensures reduced environmental impact

• Protects electrical circuits in industrial switchgear
• Suitable for use in motor control circuits
• Ideal for residential distribution boards and panels
• Utilised in commercial building electrical protection systems
• Effectively safeguards against overloads in automation systems

The maximum operating voltage at DC rated value is 500V, while it operates at 440V for single and multi-phase AC configurations.

The type C tripping characteristic is ideal for protecting circuits with high inrush currents, such as motors and transformers, ensuring that transient overloads do not cause nuisance tripping.

With a breaking capacity of 10 kA, this device can safely interrupt higher fault currents, reducing the risk of electrical fires and damage to connected equipment.

It can accommodate solid and stranded conductors ranging from 0.75 mm² to 35 mm², and finely stranded conductors up to 25 mm², facilitating versatile connections.
