Circuit protection

Circuit protection - vital in automation technology

Circuit protection in automation technology includes circuit breakers for motor protection and electronic load circuit breakers. They are used to protect the plant and the load. Whether there is a short circuit, overload or error current (imbalance between output and input current), protective devices switch off in dangerous situations. Circuit breakers can also be used for manual switching, for example, in the event of maintenance.

Security by means of compatible circit protection

Protective devices must of course be adapted to their operating conditions and process requirements. It is distinguished between the performance and characteristics of the devices:

  • Rated current
  • Voltage range
  • Number of poles and channels

Select between several applications and types and protect your system using the protection technology from Automation24.


Circuit protection for plant and load

Automation24 offers circuit protection for every requirement. The SIRIUS modular system from the company Siemens provides optimum solutions for the connection of protective technology and switching technology, for example for motor protection. Miniature circuit breakers and circuit breakers for motor protection, also known as manual motor starters, from LS ELECTRIC are a reliable and cost-effective solution for protection of your devices as well.

The rated current and the voltage range depend on various components in the plant. Available at Automation24 are for example: Siemens SIRIUS 3RV20110CA10 and and surge protector Weidmüller VPU I 3+1 R 280V/12.5KA - 1352240000. The necessary accessories can also be purchased. For multiple device protection, take a look at UL489 rated miniature circuit breaker LS ELECTRIC BK63HU 1P B1A 10kA 277VAC UL489 - 0626042163.

At Automation24 you find competitively priced circuit protection from the market leaders. Select the protective devices necessary for your application now!
