’s earth insulation lockout relay prevents motor starts
when an inherent earth leakage fault is present. The product
was designed as a result of problems encountered by manufacturing
plants operating in humid coastal conditions, such as in the sugar
industry, hosing down of motors, for example, in abattoirs, and when
operating stand-by equipment that is seldom used. Simply pressing
the ’start’ button on amachine that has been standing for a long period
of time is risky and should be avoided until the insulation level of the
motor has been found acceptable.
NewElec’s EC/ED relay solves this problem by monitoring the
insulation integrity of the motor windings and feeder cables to earth
while the motor is standing. In essence, the main contactor will be
prevented from closing into a circuit in which the insulation level to
earth has deteriorated to an unacceptable level.
Included in the protection package are the relay, an 11-pin plug-in
base and a three-phase choke.The product may be used regardless
of the starter configuration.
The selected ‘lock out’ relay model determines the acceptable
insulation level, while the fused measuring circuit protects the relay
against inadvertent damage due to incorrect connections. Compact in
design, the EC/ED is suitable for installation in flameproof enclosures.
The lock-out relay may be used on both cables and motors starting
DOL or star delta.
