Normal functioning of the thermal relay confirms serviceability of a contour.
More particularly, a thermal relay type of actuator is provided as a switch which may selectively control which of the plurality of resistors is connected.
Said device is particularly convenient to be used in industrial installations where it is desired to replace the associations of contactors, thermal relay and circuit breaker by static apparatuses.
The control unit (20) includes a delayed cycle controller (21) which overrides the thermal relay (6) control and thus delays the activating of the boiler.
A thermal relay has, as standard, auxiliary contacts that improve its operation and increase its safety.
The invention relates to a tripping slide device for a thermal overload relay.
At a minimum, temperature monitoring can provide protection from thermal runaway.
To describe the ideal overload relay for a full voltage motor starter, you need to consider the following aspects of overload relays.
However, when considering application to an overload current safety device such as a thermal relay, there is a defect that the current detection range is small and cannot be used in practice.
This overvoltage is generated by the opening of a contact (controlled by a thermal switch) which interrupts the current circulating in the magnetic ballast.
In this case, there can only be overload protection systems, which are made in the form of a thermal relay.
