MANUAL MOTOR CONTROLLER AND SUPPLEMENTARY PROTECTOR

Product description

The AS168X is a thermal magnetic high performance CBE to IEC 934

and a «supplementary protector» to UL 1077. It is capable of drasti-

cally limiting the «let-through energy» in case of short circuit interrup-

tions. The series is available in units from one to four poles for use in

AC and DC circuits. Multipole devices are connected internally and at

the handle for simultaneous operation. This applies also to combina-

tions with the switched neutral pole. Well designed screw type term-

inals at line and load side are provided for safe and easy connection

to line and load. They accept #16 to 4 AWG / 1,5 to 25 mm

The AS168X is suitable as supplementary protector under

UL 1077 / EN 60934 or as Manual Motor Controller according

UL 508 / CSA 22.2 14. Thus the Breaker has a high versatility

and is suitable for many functions:

• Motor overload protection (thermal and magnetic)

• Motor starting across-the-line (direct-on-line)

• Motor starting with motor disconnect (cos phi 0,4 – 0,5)

• Motor group installation (short capacity 5 kA)

• Control circuits

Accessories

• Auxiliary contact module

• Signal contact module

• Relay trip module

• Switched neutral pole (factory assembled)

Features

• Excellent short circuit performance (up to 10 kA)

• High limits of discrimination (due to energy limitation)

• Wide choice of characteristics (Adaptability)

• Availability of AC and DC in the same frame size

• Compact, «finger safe» design

• Ease installation (on DIN rail)

Applications

• Industrial machines

• Automation

• Aircondition, ventilation

• Transformers

• Power supplies

• Telecom systems

• Computer systems

• Test systems

• Medical equipments

Each auxiliary contact module contains one contact,

either normally open or normally closed.

Signal contact modules are linked internally with the protected

poles but not linked at the handles.

Contacts are actuated by a fault condition at the protected poles,

not by the manual operation of the CBE.

The relay trip module can be used for remote tripping of the

adjacent poles by applying a voltage to the module’s terminal.

This module allows to automatically open the neutral line when

the protected poles have been tripped.
