Cat. N° (s) : 4 033 49 to 4 035 68, 4 037 12 to 4 037 78
5. GENERAL CHARACTERISTICS
(continued)
Selectivity between two levels of protection
. The downstream circuit breaker must always have a magnetic threshold and a rated current lower than those of the upstream protection.
. Selectivity is indicated total (T) if there is selectivity up to the value of breaking capacity (according to IEC / EN 60947-2) of the downstream circuit
breaker.
Selectivity between modular circuit breakers and fuses:
. Selectivity limit at 400 V~: values in Ampere.
