Outline and Installation Dimensions
Installation and Disassembly Method
●Check that the working voltage, rated current, frequency and characteristics of the product meet the working
requirements before installation.
●It is forbidden to use the circuit breaker if damage or loose assembly.
●When the circuit breaker is used in a closed environment, and the adjacent circuit breakers are energized
simultaneously, appropriate derating is required, or a 9mm mounting clearance is kept between the adjacent
circuit breakers (this clearance can be empty or a side-mounted auxiliary module).

Shunt and undervoltage release
Install
1. Hang the hook at the upper part of the release in the
circuit breaker hanging hole;
2. Press teh hook located at the lower end of release;
3. Align the connecting rod of release with the
mechanism hole on the circuit breaker;
4. Combine the release with the circuit breaker
together, hange the hook and then release.
Disassemble
1, 2. Press the hook at the lower end of release, and
rotate it outwards;
3. Move the hook upwards after leaving the body to
remove the release.

Instantaneous Aux. Contact
Install
1. When the circuit breaker is in the OFF state, hange
the upper hook of auxiliary contact onto the circuit
breaker, and align the connecting rod with the hook of
circuit breaker mechanism;
2. When pressing the lower hook of auxiliary
contact, combine the auxiliary contact with the circuit
breaker together, release the hook of auxiliary contact,
and confirm that the auxiliary contact is firmly hung
onto the circuit breaker;
3. After installation, press the Start/Stop button of
circuit breaker to prevent no blockage of mechanism.
Disassembe
1. Press the lower hook of auxiliary contact;
2. Rotate the auxiliary contact outwards;
3. Move the hook upwards after leaving the body to
remove the auxiliary conatct.

Install AEV2s11 or AEV2s20
Installation
1. Pry the top auxiliary contact shield upwards;
2. Attach the flat side of the top auxiliary contact against the circuit breaker;
3. Align the installation position and insert it down.

Debugging and Operation
(1) Check whether the setting current range of motor circuit breaker is consistent with the rated operating current
of motor, and replace if necessary;
(2) Confirm that the motor circuit breaker for damage or abnormal sound; manually operate it several times and
check the mechanism works flexibly and reliably without blockage; the circuit breaker can put into the operation
only after passing those inspections.
(3) The product setting current has been set to the minimum value in factory. Before use, set the current to the
scale line consistent with the rated operating current of motor. If the motor trips in the starting process, increase
the current setting value appropriately until the motor circuit breaker can work normally.
(4) It is recommended to use single-core PVC insulated copper wire with prefabricated U-shaped ends in main
circuit, and the cross-sectional area of the wire is listed in table below:
