9.1. Description
The protective enclosure specifically designed for
DCBreak circuit breakers is made of stainless steel
and is pre-engineered to perform the following
functions:
• Connection to the main circuit by means of sealed
cable glands and cables (up to 6 cables)
• Connection of the signaling circuits and control
circuit of the auxiliaries by means of a connector
• Mechanical fixing to the structure of the vehicle
• Protection against shocks and impact for under-
floor applications and from the penetration of
water and polluting dust.
The dimensions of the enclosure have been
optimized and checked during dedicated type tests
to which the circuit breaker and enclosure assembly
have been subjected. The enclosure is certified as
able to withstand jets of water and dust (IP 65
protection class) and can be installed both on and
under a vehicle.
9.2. Handling
IMPORTANT! Do not lift the whole enclosure
by the handgrips (24). Use the handgrips
(24) to lift the upper shell (25) and use two
ropes (26) to lift the lower shell or the entire

enclosure.
