summary:
Standards and specifications:
SENTRON 3VL circuit breaker meets the following standards:
●IEC 60947-1，EN 60947-1
●IEC 60947-2，EN 60947-2
The isolation characteristics comply with the standards IEC 60947-2, EN 60947-2 for disconnection function (main control switch), and EN60204-1.
In addition, the SENTRON 3VL circuit breaker also meets the requirement of "breaking in emergency situations" (emergency stop switch) and has a lockable rotating operating mechanism (red yellow).
Can be used as the main control switch and emergency stop switch.
The electronic release of the circuit breaker for motor protection also complies with the IEC 60947-4-1 standard.
VL160X to VL400 circuit breakers can be equipped with a SENTRON 3VL RCD module.
The SENTRON 3VL RCD module complies with the requirements for electromagnetic compatibility in IEC 61000-4-2 to 61000-4-6, IEC61000-4-11, and EN 55011 Class B (equivalent to CISPR 11).
connection
The SENTRON VL160X-VL160 series circuit breakers are equipped with box type terminals for incoming and outgoing lines, suitable for multi strand wires, flexible copper bars, braided wires with terminal sleeves, and screw type terminals for flat connectors. In addition, different incoming terminals can be provided for specifications such as VL630-VL1600 (630 A-1600 A).
For SENTRON VL160X-VL1600 circuit breakers, provide suitable accessories for screw type terminals for fixing and moving copper bars or cables.
SENTRON VL160X-VL1600 circuit breakers can be equipped with busbar connectors. These busbar connectors are designed for standardized busbar connections and can be used for front or rear board connections. SENTRON VL1600 circuit breaker comes standard with a front busbar connector.
SENTRON VL160X Circuit Breaker
The main components of SENTRON VL160X circuit breaker are three conductive circuits with input and output terminals. The configuration of static and dynamic contacts can utilize the magnetic repulsion of the contacts under short-circuit conditions. This series of circuit breakers is used in conjunction with an arc extinguishing chamber to generate a dynamic impedance that achieves current limiting performance by reducing I2t and Ip energy.
The release is assembled in the factory and designed with fixed or adjustable overload release and fixed short-circuit release in each pole. The circuit breaker is equipped with a free release mechanism.
There are double isolation auxiliary rooms on both the right and left sides of the circuit breaker operating mechanism, used for installing auxiliary release devices and auxiliary switches.
SENTRON VL160-VL630 Circuit Breaker
The current circuit layout, main contact configuration, and on-off mechanism layout are the same as the SENTRON VL 160X series circuit breaker.
The SENTRON VL160-VL630 release has the following characteristics:
Provide thermal magnetic release and electronic release.
The overload release and short-circuit release of the thermal magnetic release can be adjusted.
SENTRON VL800-VL1600 Circuit Breaker
The current circuit layout, main contact configuration, and on-off mechanism layout are the same as the SENTRON VL160-VL630 series circuit breaker.
SENTRON VL800-VL1600 circuit breaker only provides electronic release.
