standard.
Applications
HRCII fuses are often used to protect motor control circuits,
together with contactors and overload protection relays.
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.
This arrangement allows the use of a fast-acting *fuse characteristic which ensures excellent short-circuit current and
energy limiting for optimum protection.
*CSA defined HRCII characteristics inherently give more time delay than
HRCI fast acting fuses.
For full “no damage” protection under all fault conditions
(Type 2 Coordination - per IEC 947-4), and to avoid nuisance fuse operation, the fuse, relay and contactor characteristics must be considered together to ensure that:
- the contactor is protected at all times
- 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.
This is particularly necessary in the case of IEC style contactors, which require more accurate coordination to ensure
optimum system reliability.
In addition CSA certified, Edison HRCII fuses are also tested 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.
For further information on fuse selection and coordination
contact your local Edison Fusegear representative.
