3VU Circuit BreakerDetailed product description：

3VU13 and 3VU16 circuit breakers are compact circuit breakers with a maximum rated current of 30 kW and 63A. Work according to the principle of current limiting. Can be used for starting, disconnecting, overload and short circuit protection of motors or other loads; 3VU13 and 3VU16 can also be used as motor phase failure protection.

characteristic

When used for motor or equipment protection, the above circuit breakers are equipped with overcurrent instantaneous release and inverse time delay overload release.
Due to the overload protection of the starter combination device itself, the 3VU16 used for starter combination is only equipped with overcurrent instantaneous release.
Circuit breakers and contactors can be combined into a fuse free combination starting device.
When its rated working current is 0.1-52A, it can be used for overload protection, short circuit protection, and phase failure protection of electric motors, and can also be used as a starter for infrequently starting and disconnecting electric motors; When its rated current is 0.1-63A, it can be used for line protection.
3VU13 and 3VU16 circuit breakers are suitable for any climate. Design according to a good operating environment in a closed room (e.g. no dust, corrosive gases). Before installation and use in dusty and humid rooms, they must be properly sealed and treated. The various operating parameters of circuit breakers, including allowable ambient temperature, maximum breaking capacity, tripping action current, and other limiting operating parameters, are provided in the technical data and tripping characteristics.

SIRIUS 3RV circuit breaker is a compact current limiting circuit breaker. It can safely cut off the power supply in case of a short circuit, and also prevent overload of the load and equipment. In addition, it can also be used as a load conversion or isolation switch between equipment and power supply lines when maintenance or component replacement is required.

Like all SIRIUS devices, this circuit breaker can also be installed in parallel, with a maximum temperature of up to 60 ° C. In addition to the usual closed/open position of the circuit breaker, there is also a trip indication position. Through a connection module, SIRIUS circuit breakers can be easily connected to SIRIUS contactors and soft starters without the need for wiring ports.

The intuitive and structured series design can be seamlessly connected with other SIRIUS products in terms of electrical, mechanical, and appearance. For example, contactors, soft starters, and overload relays. 4 specifications, with a current range of up to 100A, equivalent to a power of 45kW at 400V AC.
