Output to 16A 280 Vac
DC Control
FEATURES/BENEFITS
Compact size
Spring terminals
Tight zero-cross window for low EMI
Touch-proof terminals
Designed for medium-power applications
DESCRIPTION
The Series X relays are designed in a thin compact
plastic package. The X relays offer touch-proof spring
terminals for ease of use and user safety. With its
medium-power handling capabilities and compact
size, the Series X is an excellent choice for medium-
power AC loads.
APPLICATIONS
Heating control
Motor control
Uninterruptible power supplies
Light dimmers
Industrial and process control
On/Off controls of medium-power AC equipment
APPROVALS
Series X relays are UL pending.
