Class CB Automatic Transfer Switch with Overcurrent Release and Rated Current WATSN-800
Class CB
ATSE with overcurrent release
Its main contact can be closed and used to break short-circuit current
WATSN series automatic transfer switch is a class CB automatic transfer switch if it
adopts a circuit breaker with overcurrent release as the actuator. With selective
protective function, it can provide short-circuit and overload protection for
downstream loads and cables. Its making and breaking capacity is significantly
higher than other components such as contactors and relays.

High-performance product
● High breaking capacity (class CB)
● Operation breaking capacity is equal to 100% of ultimate breaking capacity (class
CB)
● Provide high current-limiting capacity and total economic selectivity (class CB)
● Provide high short-circuit making capacity and rated short-time withstand capacity
(class PC)
Easy connection and installation
● No need to derate in both horizontal and vertical installation
● No need to derate for lower incoming lines
Higher reliability
● Alarm for wrong neutral connection
● Automatic signal cutoff in case of unsuccessful transfer
Smart communication
● RS485 communication interface and Modbus-RTU communication protocol
● Provide four remote functions including telecommand, telemetry, telecontrol, and
telereg
Notes:
Controller types include: A - Terminal type; B - Basic Type; D- Smart type
Frame current levels: 63, 100, 160, 250, 400, 630, 800, 1000, 1250, 1600
Rated current: Depending on different frame levels, the release is selected by the user (by making reference to NSX/NS circuit breaker sample)
Selectable number of poles: 2 (only for iC65 series), 3, 4 (all series)
Electric device Class: CB - with short-circuit and overload protection
Operation modes: R - Automatic change and automatic recovery; S - Automatic change without automatic recovery; I - Mutual standby
Additional functions: X- Fire protection linkage; F- Feedback signal; I - Current monitoring module (only available for Type D controller)
Release – class CB. Release with different protection range can be selected based on user needs.
*: Two installation methods can be provided: Device-mounted and panel-mounted.
Please add a note if panel installation is required. iC65 products do not support
panel-mounted controllers.
**: F- Feedback signal function (including position feedback and alarm feedback, please add explanatory text if necessary).800-1600A series products include a group of position feedback and a group of alarm feedback as standard. For 63A and lower current products, only a group of position feedback is available.
