Section 1: General information
IMPORTANT
IT IS RECOMMENDED THAT APPROPRIATE INTERPHASE BARRIERS BE
INSTALLED BETWEEN INSIDE AND OUTSIDE PRIMARY TERMINALS
WITH ALL REAR-CONNECTED CONFIGURATIONS ON DRAWOUT
CASSETTES AND FIXED TYPE CIRCUIT BREAKERS TO ENSURE
INSULATION INTEGRITY. THESE INSTRUCTIONS ARE PROVIDED FOR
EATON SUPPLIED INTERPHASE BARRIERS.
Eaton supplied interphase barriers are made from a exible
rubber type material, and when installed, provide the proper
insulation integrity. Drawout cassettes and xed circuit break-
ers are designed for the simple installation of these barriers.
Section 2: Drawout cassette barriers
Dove tail shaped mounting slots are provided in the primary
backpan of the cassette for mounting Eaton supplied inter-
phase barriers (Figure 1).
