HRCII CURRENT LIMITING FUSES

600V a.c. or less, 250V d.c. 200,000 A.I.R. to CSA C22.2 No. 106 M92

Edison HRCII Fuses

- Engineered for long life reliable protection.

- Non deteriorating silver plated links.

- High grade ceramic bodies.

For full “no damage” protection under all fault conditions

(Type 2 Coordination - per IEC 947-4), and to avoid nui-

sance fuse operation, the fuse, relay and contactor charac-

teristics must be considered together to ensure that:

- the contactor is protected at all times

- Plated external metalwork.

- Interrupting rating certified to 200,000 Amps RMS sym-

metrical, to CSA C22.2 No. 106M1992.

- HRCII fuse manufacturing is certified to ISO 9002 (1987)

standard.

- the overload relay operates before the fuse (up to the

relay’s safe interrupting limit), or

- the fuse safely clears the circuit and limits high level

fault currents to prevent damage to the relay or to the

contactor.

Applications

HRCII fuses are often used to protect motor control circuits,

together with contactors and overload protection relays.

This is particularly necessary in the case of IEC style con-

tactors, which require more accurate coordination to ensure

optimum system reliability.

In this application overload protection of the installation is

provided by the thermal overload relay, and the fuses are

usually rated higher than the motor full load current to avoid

nuisance blowing under starting inrush currents.

In addition CSA certified, Edison HRCII fuses are also test-

ed and certified to IEC and British standards. IEC269:2 and

BS88:2 include tightly specified characteristics to ensure full

interchangeability with other manufacturers HRCII fuses

certified to these standards.

This arrangement allows the use of a fast-acting *fuse char-

acteristic which ensures excellent short-circuit current and

energy limiting for optimum protection.

For further information on fuse selection and coordination

contact your local Edison Fusegear representative.

*CSA defined HRCII characteristics inherently give more time delay than

HRCI fast acting fuses.
