STOTZ selective main circuit breakers are suitable to

disconnect and release electric circuits.

STOTZ selective main circuit breakers can be operated

by ordinary people. The contact position is indicated clearly

and unambiguously by (1) the position of the operating lever,

clearly identified by the 0-I positions, and (2) also by a

separate position indicator (RED = on, GREEN = off).

Selective main circuit breakers S 750 operate voltage

independent (VI) according to E DIN VDE 0641-21. i.e. they

do not need a control circuit to make or break a contact.

STOTZ selective main circuit breakers S 750 are available with

tripping characteristic E (E = Exact)

They are particularly suitable for the following applications:

− in the meter-mounting board as the main isolating device

for the customer

− in main distribution frames or switchgear as selective

group or back-up breaker, especially where a high degree

of continuity of supply is required, e.g. for “installations for

gathering of people”, in “medical locations” and for the

supply of safety equipment.
