Time Delay Relays
The E-T-A series 664 is a voltage activated thermal time
delay relay suitable for a wide range of applications and
process control applications. The excitation circuit and
load switching changeover contacts are electrically sepa-
rate. Delay times can be specified in fixed steps up to sixty
seconds.
Motor Start Switches
E-T-A Motor Start Switches offer a simple and rugged
method of disconnecting the auxiliary windings and start
capacitors of single phase AC motors. Featuring current
sensitive bimetal controlled mechanisms, their switching
time is a function of the starting current and its duration.
Motor Protection Controls
Series 2-6500 and 2-6700 over current protection devices
with automatic reset actuation are particularly suitable for
motor control and similar applications. They are designed
to distinguish between temporary overloads, for example
motor start conditions, and sustained faults such as
locked rotor. A reset delay provides an opportunity for the
equipment protected to cool before power is re-applied,
and the need for operator intervention is avoided.
Door Locking Relays
E-T-A door locking relays are designed to increase the
safety of washing machines, dishwashers, microwave
ovens and similar appliances. By ensuring that their doors
cannot be opened whilst the machine is operating, users
are protected from moving parts, high temperatures,
steam, harmful radiation and other hazards.
Suited both to domestic and heavy duty professional
equipment, these relays offer a choice of thermal or
magnetic sensing element, with versions for current and
voltage control.
Energising the relay activates the door locking mechanism,
while de-energisation keeps the door locked for a pre-
determined time until it is safe to be opened again.
The E-T-A door locking relay series 6510 has been
specifically developed to comply with the requirements of
IEC 335-2-25 (Safety for Household and Similar
appliances). The product is in modular form and offers
door closed signalling and locking possibilities for
applications such as microwave ovens with pyrolytic
cleaning.
The choice of door locking relays available provides
flexibility for the designer while ensuring that the legisla-
tive demands of different markets can be successfully
satisfied.
