What is the purpose of this Siemens Motor Protection Circuit Breaker?
This Siemens Motor Protection Circuit Breaker is designed to protect motors from overloads and short circuits. It has a magnetic trip function that disconnects the circuit when it detects a sudden surge in current, such as in the event of a short circuit.
What are the specifications of this circuit breaker?
The circuit breaker has 3 poles and a rated current of 3.2 A. It can handle voltages up to 690 V ac and has a breaking capacity of 100 kA. The trip class is 10 A-release with a range of 2.2 to 3.2 A for the N release. The dimensions are 45 x 106 x 96.9 mm.
What is the mounting position for this circuit breaker?
The 3RV2011-1DA20 can be mounted in any position. It can be fastened by screw and snap-on mounting onto a 35 mm standard mounting rail according to DIN EN 60715.
What type of electrical connection does this circuit breaker use?
The 3RV2011-1DA20 uses spring-loaded terminals for the main current circuit. The arrangement of electrical connectors for the main current circuit is at the top and bottom.
What is the required spacing for this circuit breaker?
The required spacing for this circuit breaker varies depending on the voltage. For example, for live parts at 690 V, the required spacing is 50 mm downwards and upwards, 0 mm backwards, 30 mm at the side, and 0 mm forwards.
What type of conductors can be connected to this circuit breaker?
The circuit breaker can connect to solid or stranded conductors with cross-sections of 2x (0.5 ... 4 mm²), and finely stranded conductors with or without core end processing of 2x (0.5 ... 2.5 mm²). It can also connect to AWG cables for main contacts of 2x (20 ... 12).
What safety-related data is available for this circuit breaker?
The B10 value for this circuit breaker, with a high demand rate according to SN 31920, is 5 000. The proportion of dangerous failures, with both low and high demand rates according to SN 31920, is 50%. The failure rate with a low demand rate according to SN 31920 is 50 FIT.
