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.
