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

Stop rogue current flow in its tracks with this Siemens MCB. It's designed to automatically interrupt a circuit when an overload or short circuit occurs, protecting your equipment from damage. The unit has a 2-pole configuration, so it's suitable for protecting either two 120V circuits or a single 240V circuit. You can install it easily by clipping it onto a DIN rail beside the electrical appliances you want to protect. It's a versatile option for industrial, manufacturing and engineering settings. You can also use it to take care of electrical safety in residential buildings.

• Wide operating temperature range between -25°C and +55°C for use in harsh conditions
• Compact dimensions of 36 (W) x 90 (H) x 76mm (D) take up minimal space on a packed DIN rail
• Can be combined with components such as shunt releases and remote operating mechanisms for greater functionality

It's a type C circuit breaker, meaning it instantly trips if there are current surges 5 to 10 times the rated current of 2A. This high surge capacity makes it suitable for heavy-duty commercial applications.
