Information about installation, assembly and attachment

3VA1 160 1-pole and 2-pole molded case circuit breakers
3VA1 160 1-pole molded case circuit breakers
To attach these to a DIN rail, a 3VA9181-0SH10 DIN rail adapter is required. This DIN rail
adapter is not attached by screws to the molded case circuit breaker, but simply snapped
into place on the rear panel.
3VA1 160 2-pole molded case circuit breakers
To attach 2-pole molded case circuit breakers to 35 mm DIN rails, a 3VA9182-0SH10 DIN
rail adapter is required. This adapter is fitted with threaded nuts. The molded case circuit
breakers are screwed onto the adapter by means of the fastening screws supplied with the
circuit breakers. The nuts supplied with the circuit breakers are not required.
3VA1 100 and 3VA1 160 3-pole and 4-pole molded case circuit breakers
To attach 3-pole and 4-pole molded case circuit breakers to 35 mm DIN rails, a 3VA9187-
0SH10 DIN rail adapter is required. This adapter is fitted with threaded nuts. The molded
case circuit breakers are screwed onto the adapter by means of the fastening screws
supplied with the circuit breakers. The nuts supplied with the circuit breakers are not
required.
3VA1 100 and 3VA1 160 3-pole and 4-pole molded case circuit breakers with side mounted residual
current device
The 3VA9187-0SH20 DIN rail adapter has been specially developed for use with molded
case circuit breakers combined with side mounted residual current device. This DIN rail
adapter is also fitted with threaded nuts so that the molded case circuit breaker/residual
current device assembly can be fastened to it by means of the screws included in the scope
of supply of both devices.
Assembly instructions
The molded case circuit breaker must first be attached to the DIN rail adapter. 3-pole molded
case circuit breakers must be attached such that their right-hand edge (when viewed from
above) is flush with the DIN rail adapter. With 4-pole molded case circuit breakers, the N
pole is situated opposite on the left-hand side (when viewed from above). The screws are
inserted in the fastening holes between phases 1 and 2, and between phases 2 and 3, in the
molded case circuit breaker.
After the molded case circuit breaker has been attached to the DIN rail adapter, the residual
current device must also be mounted on the adapter. After the residual current device has
been secured in position on the DIN rail adapter, the main current paths of the residual
current device and the molded case circuit breaker must be checked to ensure that they are
properly aligned and connected.
