APPLICATIONS: used in order to signal the position ON or OFF of the MCCB's.
CHARACTERISTICS: they are identified by the grey colour and with the AX symbol on the product.

APPLICATIONS: used in order to indicate the circuit breaker tripping status.
NOTES: GWD8502 must be placed to the left of the circuit breaker lever.
GWD8503 must be placed to the right of the circuit breaker lever.
CHARACTERISTICS: they are identified by the grey and black colours and with the AL symbol on the product.

APPLICATIONS: allows the remote release of a MCCB'S when a certain voltage is applied to its terminals. When the release is powered, the contacts and the operating lever of the MCCB's assume the tripped position.
NOTE: The operating voltage range is 85% to 110% in AC and 75% to 125% in DC.
CHARACTERISTICS: they are identified by the grey colour and the SH symbol on the product.

APPLICATIONS: allows the remote tripping of a RCBO's of MSXD series via NO push button connected.
NOTE: voltage-independent release unit.
The release unit must be positioned external on the right side of the MCCB's.

APPLICATIONS: allows the remote release of a MCCB'S when the voltage applied to its terminals is between 35% and 70% of its rated voltage. When the release is not powered, the contacts and the circuit breaker operating lever assume the tripped position.
NOTE: they prevent the circuit breaker from closing until the voltage is greater than at least 85% of its rated voltage.
CHARACTERISTICS: They are identified by grey and black colours and with the UV symbol on the product.

APPLICATIONS: n order to allow remotely tripping of a circuit breaker when the voltage applied to its terminals is between 35% and 70% of its rated voltage. When the undervoltage release is not supplied, the contacts and the circuit breaker lever assume the circuit breaker tripping status.
NOTE : they prevent the closing of circuit breaker until the voltage exceeds at least 85% of its rated voltage.
The undervoltage release must be mounted outside, to the right of the crcuit breaker.
CHARACTERISTICS: They have 500ms delay time.
 

APPLICATIONS: allows the MCCB'S remote opening and closing depending on the electrical signals received.
CHARACTERISTICS: to be mounted on the front of the MCCB's.

NOTE: to create the lever interlock system it is necessary to provide and install both the left and right interlocks, depending on the size of the switch.Interlocks can also be used in the presence of motor operators or rotary handles.
CHARACTERISTICS: mechanism to be fixed on the front of both equal size 3 or 4 poles circuit breakers.

NOTE: the wire interlock consists of two mechanisms connected by a steel cable. The mechanisms are fixed on two circuit breakers, limited by the length and bending capacity of the wire. To create the wire interlock system it is necessary to provide and install a mechanism for each interlocked circuit breaker.
The cable is to be ordered separately.  Interlocks can also be used in the presence of motor operators or rotary handles.
CHARACTERISTICS: mechanism to be fixed on the front of both 3 or 4 pole circuit breakers (also with different sizes).
The circuit breakers can be placed in separate cubicles and at different heights.

CHARACTERISTICS:cable length 1m

APPLICATIONS: allows the circuit breaker lever to be locked in the ON or OFF status using up to 3 padlocks.
NOTE: tthe locking devices for models 125A, 160A and 250A accept padlocks with a diameter of 5mm.
Locking devices for models from 400A to 1600A accept padlocks with a diameter of 8mm.

APPLICATIONS: allows the quick replacement of the switch, without the need to interfere with the connections.
NOTE: to obtain the circuit-breaker in plug-in version, in addition to its fixes base, you need to provide the conversion kit.
CHARACTERISTICS: the circuit breaker in the plug-in version is automatically locked in the base when the operating lever is in the ON position. It can't be removed until the operating lever is in the OFF or tripped position.

APPLICATIONS: allows the quick replacement of the of the MCCB's without the need to work on the connections.
NOTE: tto obtain the circuit-breaker in plug-in version, in addition to the transformation kit, you need to provide its fixed base.

NOTE: they can be oriented and used as front or rear terminals

APPLICATIONS: to be considered in case of a MCCB's in plug-in version with internal accessories. Requires 1 plug for each internal accessory (auxiliary contact or opening release).
NOTE: tto obtain the MCCB'S in plug-in version with internal accessories, in addition to the socket, a plug must be installed inside the fixed base.
 

APPLICATIONS: to be considered in case of a MCCB's in plug-in version with internal accessories. Requires 1 plug for each internal accessory (auxiliary contact or opening trip unit). Identical socket for each accessory type.
NOTE: to obtain the MCCB'S in plug-in version with internal accessories, in addition to the socket, a plug must be installed inside the fixed base.

APPLICATIONS: terminals for the front connection of busbars or cable terminals. 

APPLICATIONS: terminals for the rear connection of busbars or cable terminals.
