Short circuit protection

Type 1 protection implies that after a short circuit, the device under test will no longer be in a functioning state. The product

variants listed in the table hereunder are suitable for use on a circuit capable of delivering not more than 5,000 symmetrical

Amperes, 240 Volts maximum when protected by fuses. Tests at 5,000 A were performed with Class RK5 fuses; please

refer to the table below for maximum allowed Ampere rating of the fuse. Use fuses only.
