16A 1-phase C-type automatic fuse / circuit breaker Siemens 5SX21 C16 230VAC / 400VAC

An overcurrent circuit breaker is a component of an electrical installation whose function is to break the continuity of a circuit when the current exceeds the safe value for that circuit. The circuit breaker is designed to control and protect against the effects of overloads and short circuits of consumer circuits of the installation, as well as household electrical appliances. It is designed for repeated use.

Multipurpose automatic fuse for DIN rail mounting. Automatic circuit breaker can be used in various application such as:

• Electrical cabinet
• Electrical device
• Industrial electrical installations
• Household electrical installation
• Protecting electrical motor (Large motors require slow fuses such as D-class or even slower)
