Terminal covers/phase barriers:
Sealable terminal covers can be installed on the input and output side of the 3VL molded
case circuit breakers. They offer degree of protection IP30 for fixed-mounted or withdrawal
molded case circuit breakers in the connected position. In addition, extended terminal covers
provide separation between the phases if uninsulated busbars or cables are used
Phase barriers provide insulation on the input and output side of the molded case circuit
breakers. They can be mounted in the specially formed slots on the input and output sides of
the molded case circuit breakers. They can be used in conjunction with other connection
accessories (except terminal covers). The phase barriers can be used with fixed-mounted,
plug-in and withdrawable molded case circuit breakers. Terminal covers must be used if the
molded case circuit breakers are mounted immediately next to each other (see the section
Mounting and safety clearances).
