the unit should it be outside its cassette. Installers will

also find it particularly valuable for top-tier mounted

circuit breakers. Note: Users who already possess a

‘Titan’ handling truck for the original M-PACT cir-

cuit breaker can now obtain a conversion kit.

Automatic Transfer Switches

(A.T.S.)

The ATS ensures the continuity of electric supply to

an installation with minimum interruption by making

an automatic transfer from the normal supply to emer-

gency source. The emergency source can be either a

transformer or generator supply and the M-PACT air

circuit breakers are governed automatically by the

transfer controller, which selects the available source.

Circuit breaker insertion interlock

By incorporating this optional security interlock

device into a system, it prevents the inadvertent

insertion of an incorrectly rated withdrawable circuit

breaker into a cassette.

Cassette interlock

Available for withdrawable circuit breakers only, this

sophisticated interlock system secures the circuit brea-

ker in the disconnected position by means of a Ronis or

Profalux key. When the key is removed, the safety shut-

ters are automatically locked in position, thus preven-

ting access to the contacts and also ensuring that the

racking mechanism is not operable. For lock and key

details refer to key interlock facility section (p. A.23)
