What type of fuses does a QMB322TW accept?

Issue:
Application

Product Line:
Panelboards.

Environment:
QMB Switches.

Cause:
Selection.

Resolution:
This QMB switch accepts Class H or Class K fuses as standard.  Class R fuses can also be installed , but to reject all fuse types except Class R fuses, a rejection kit QMB36R, needs to be also installed.
Since the QMB322TW switch is a twin 60A switch unit, two QMB36R kits would be needed.
