Protection device for opening and closing pushbuttons - PBC (Fig. 18)
This accessory is applied to the safety cover of the circuit-breaker and is available in two
versions:
• Pushbutton protection device, which blocks operations on both the opening and closing pushbuttons
unless the special key is used.
• Padlockable pushbutton protection device, which makes it possible to block either or both pushbut-
tons and lock the covers in place. It does not trip the breaker as a standard "Padlock device" would.
• PBC is an alternative to PLC padlocks.

IP30 Protection (Fig. 19)
Supplied with every circuit-breaker, the cover frame is installed on the door of the switchgear
to achieve IP30 degree of protection on the front part of the circuit-breaker.

IP54 Protection (Fig. 20)
— This transparent cover completely protects the front of the circuit-breaker, enabling an IP54 degree of
Fig. 18 protection to be achieved. This accessory is provided with double key lock (same or different keys).

Terminal covers – HTC / LTC (Fig. 21)
These accessories are installed over in the terminal area, thereby reducing the risk of direct contact
with the live parts of the circuit-breaker. Two versions are available for E1.2: HTC high terminal covers
and LTC low terminal covers.

Separators - PB (Fig. 22)
These protection devices increase the insulation distance between adjacent phases. They are available 06
for all the frames.

— 0-ARC Distance top cover
Fig. 19
This accessory allows the circuit-breakers to reach the 0-arc distance performance. Installable on the
fixed part of E2.2, E4.2 and E6.2 gives the possibility to dimension the cubicle at the same height of the
fixed part. The 0-arc distance top cover is not compatible with the AUP auxiliary contacts IEC version,
but alternatively it is possible to install the AUP auxiliary contacts UL version.

Remote Racking Device - RRD
The Remote Racking Device (RRD) operates Emax 2 circuit breakers without being in front of the gear.
— The remote control is connected to the main device through 10mt cable that allows the Racking-in/out
Fig. 20 command from a remote location. The cable length guarantees enough distance from the arc flash
boundary of traditional low voltage switchgears. The RRD can only operate with the circuit breaker in
open position and discharged springs. The RRD for switchgear and controlgear has been investigated
by UL in accordance with the Standards UL 2876 and CSA-C22.2 (n.14).
