Description
Sealable cover
There is one sealable cover for thermal overload relays and one for solid-state relays; both
are compatible for use with all sizes. The 3RV2908-0P cover can be used as an accessory
for 3RU2 thermal overload relays and 3RV2 motor starter protectors/circuit breakers (acc. to
UL).
The sealable cover can be used to protect the rotary button for setting the rated motor
current and the CO contact for the tripping classes (3RB31 only) against unauthorized
manipulation.
