Page 43: Functions
Functions 3RV motor starter protectors meet the requirements for motor and system protection according to IEC 60947‑2 / DIN VDE 0660‑101. Motor and system protection is achieved using the following functions: • Overload protection • Short-circuit protection • Phase loss sensitivity SIRIUS 3RV Motor Starter Protectors Equipment Manual, 09/2024, A5E03656507320A/RS-AL/012...
Page 44: Overload And Short-Circuit Protection
Functions 6.1 Overload and short-circuit protection Overload and short-circuit protection Overload protection The rated current of the motor requiring protection (see rating plate) is set on the setting scale. This sets the integrated overload protection to the motor current. Short-circuit protection The short-circuit release is factory-set to a multiple of the motor starter protector's rated current (top value on the setting scale).
Page 45: Tripping Characteristics
Functions 6.1 Overload and short-circuit protection 6.1.2 Tripping characteristics The time-current characteristic, the current-limiting characteristics, and the I t characteristics have been determined according to DIN VDE 0660/IEC 60947. In the case of the time-current characteristic, the tripping characteristic of the inverse-time delayed overload release (thermal overload release) applies for alternating current with frequencies from 0 Hz up to 400 Hz.

Page 48: Phase Loss Sensitivity
Functions 6.2 Phase loss sensitivity Phase loss sensitivity The phase loss sensitivity (not in the case of 3RV20..-..-0DA0, 3RV23, 3RV27 and 3RV28) of the motor starter protector ensures that it trips in good time in the event of a phase failure or significant phase unbalance.
Page 49: Protection Of Single-Phase Loads
Functions 6.3 Protection of single-phase loads Protection of single-phase loads The 3RV20..-..-0DA0 motor starter protectors for system protection and 3RV27 / 3RV28 circuit breakers according to UL 489 do not feature phase asymmetry detection. Therefore these devices can be used for the protection of single-phase or two-phase loads. The 3RV20..-..-0DA0 motor starter protectors for system protection do not have UL approval.
Page 50: Test Function
Functions 6.4 Test function Test function The TEST slide / TEST pushbutton can be used to check whether the operational motor starter protector is working correctly (not on the 3RV23 / 3RV27 / 3RV28 circuit breakers in sizes S00 and S0). The tripping of the motor starter protector can be simulated by operating the slide / pushbutton.

Configuration 7.4 Motor protection Motor protection The tripping characteristic of 3RV10 / 3RV20 / 3RV21 motor starter protectors is primarily designed for protecting three-phase motors. The rated current I of the motor to be protected (see nameplate) is set on the setting scale. The short-circuit release is factory-set to a multiple of the motor starter protector's rated current (top value on the setting scale).

Configuration 7.5 System protection System protection 3RV20 and 3RV21 motor starter protectors are also suitable for protecting systems. To prevent premature tripping caused by phase loss sensitivity, the load applied to each of the three current paths of the motor starter protector in standard version must always be the same.

Configuration 7.6 Motor protection with overload relay function Motor protection with overload relay function 3RV21 motor starter protectors with overload relay function have the same overload and short- circuit release characteristic as 3RV20 motor starter protectors. However, the overload releases have no effect on the motor starter protectors' breaker latching mechanism. In the event of an overload, the motor starter protector remains on.

Configuration 7.7 Using 3RV1011 and 3RV2 motor starter protectors with highly energy-efficient motors (IE3 / IE4) 7.7.1.3 Rated motor current/setting scale For motor protection, the motor's rated current must be set on the motor starter protector's setting scale. The new IE3 / IE4 motors generally have lower rated currents. This can lead to situations in which a motor starter protector with a lower rated current has to be chosen for the same motor rating.
Page 85: Technical Modifications/Restrictions Of 3Rv2 Motor Starter Protectors
Configuration 7.7 Using 3RV1011 and 3RV2 motor starter protectors with highly energy-efficient motors (IE3 / IE4) limit is 17.33 times the current setting (260 A/15 A = 17.33). In this example, the distance from the response limit of 13.86 times the current setting in the case of motor starter protector A increases to 17.33 times the current setting in the case of motor starter protector B.

Configuration 7.8 Short-circuit protection for starter combinations Short-circuit protection for starter combinations 3RV23 MSP for starter combinations 3RV23 MSPs for starter combinations are motor starter protectors without overload releases. They are always used in conjunction with a contactor and overload relay, as the motor starter protector alone is not able to protect the motor and itself against overloads.

Page 88: Transformer Protection
Configuration 7.9 Transformer protection Transformer protection Protection against inrush currents When control transformers are protected on the primary side, the high inrush currents generated at the time the transformers are switched on often cause spurious tripping in the protective devices. The short-circuit releases of motor starter protectors for transformer protection (3RV24, 3RV28) are set to a higher value than in the case of the 3RV20 motor starter protectors.

Configuration 7.10 Main switch 7.10 Main switch 3RV2 motor starter protectors satisfy the features of main switches according to IEC 60947‑2. 3RV20 and 3RV21 motor starter protectors are also suitable for protecting systems. In order to prevent premature tripping caused by phase loss sensitivity, the charge applied to each of the three current paths must always be the same.
Page 90: Fuse Monitoring
Configuration 7.11 Fuse monitoring 7.11 Fuse monitoring The 3RV1611‑0BD10 circuit breaker is used for fuse monitoring. A current path of the circuit breaker is connected in parallel to each fuse. When a fuse fails, the current flows via the parallel connected current path of the circuit breaker, and trips it. Safety information DANGER Hazardous voltage.
Page 91 Configuration 7.11 Fuse monitoring Auxiliary switch functions The circuit breaker for fuse monitoring can be equipped with a transverse or lateral auxiliary switch. The auxiliary switch signals the tripping of the circuit breaker and thus the failure of the fuse. The auxiliary switch causes an all-pole disconnection of the faulty circuit by means of a corresponding switching device.
