3RV1 circuit breakers

SIRIUS System Manual

2-13

2.3 Field of application/variants

The tripping characteristics of the 3RV1 circuit breakers are designed prima-
rily to protect three-phase induction motors.
The circuit breakers are therefore also referred to as motor protecting 
switches.
The 3RV1 circuit breakers for motor protection are limited to the protection 
of systems.

2.3.1 Motor protection

Set current

The current of the motor that is to be protected is set on the adjustment 
scale. The short-circuit release is set at the factory to 12 times the value of 
the rated current of the circuit breaker. This ensures problem-free startup 
and reliable protection of the motor.

Phase loss
sensitivity

The phase loss sensitivity of the circuit breaker ensures that it is tripped in 
good time in the event of the loss of a phase and the resulting overcurrents 
in the other phases.

CLASS10/CLASS20

Circuit breakers of frame sizes S00 to S3 with thermal overload releases 
comply with tripping class 10 (CLASS 10). Circuit breakers with the 
CLASS 20 tripping characteristic are available for frame sizes S2 and S3 in 
difficult startup conditions.

2.3.2 Transformer protection

Inrush current

In the case of primary protection of control transformers, the high inrush 
currents that occur when the transformers are switched on often result in 
the unwanted tripping of the protective devices.
The 3RV1 circuit breakers with frame sizes S0 and S2 therefore have over-
current releases for the protection of transformers that are set at the factory 
to approximately 19 times the rated current. This makes it possible to pro-
tect transformers in which the inrush currents reach peak values of up to 30 
times the rated current with circuit breakers in the primary circuit.

In the case of 4AM control transformers with low inrush current (Siemens 
control transformers, for example), this is not required. 3RV1 circuit brea-
kers can be used here for motor protection.

2.3.3 Starter protection

The 3RV13 starter protection switches are circuit breakers without overload 
releases. They are used together with a contactor and overload relay if the 
circuit breaker is not to be triggered in the case of overload tripping.
