Class J have a high rupturing capacity (HRC) and are used for new installations.
fuse of a high breaking capacity
fuse of high breaking capacity
The breaking capacity is determined by the installation rules (IEC 60364 standard):
Breaking capacity of the breaker could be modified in this kind of situation.
Moreover one circuit breaker must have a breaking capacity assigned in the following cases:
The invention relates to an electric fuse-link, especially a low-voltage high-breaking-capacity (l.v. h.b.c) fuse-link (1).
H.v.h.b.c. fuses are located outside the container (3) in air.
Disclosed is an arcing chamber for a heavy-duty circuit breaker that can be filled with a quenching gas.
the vulgarizing of strong breaking capacities (50 kA and 63 kA),
the aim of the invention is to improve the breaking ability of vacuum interrupter in the medium- and high-voltage range.
Used for various applications, they combine design, rapid switching capacity and high reliability.
The nominal voltage is 600 V or less, and a class K1 provides an interruption capacity of 200 kA, whereas class K5 and K9 have an interruption capacity of 100 kA and 50 kA.
The nominal voltage is 600 V or less and the interruption capacity is 200 kA.
Two flush changeover contacts, and a pump control contact with 4A cutoff power.
