Description:
The Powerex CR03AM Lead
mount Phase Control SCRs are
glass-passivated thyristors for use
in low-power control and rectifica-
tion. These devices are molded
epoxy plastic types.
Features:
Glass Passivation
High Current Pulse
Application Use
Applications:
Fault Interrupters
Gas Ignitors
Static Switch
Motor Control
Ordering Information:
Example: Select the complete
seven or eight digit part number
you desire from the table - i.e.
CR03AM-8 is a 400 Volt, 0.3
Ampere Phase Control SCR.
