* Note: When conduit style G1/2 (PF1/2) is required, change the 4th digit in the catalog listing to the letter D. For example, GLAA01A1A would change to GLAD01A1A
for G1/2 conduit. When conduit style PG13,5 is required, change the 4th digit in the cagalog listing to the letter B. For example, GLAA01A1A would change to GLA-
B01A1A for PG13,5 conduit.
** Positive opening occurs.
† Contacts 11-12, 13-14 operate in CCW direction. ‡ Contacts 21-22, 23-24 operate in CW direction.
