3 Definitions
For the purposes of this European Standard, the definitions given in EN 50107-1 and EN 61347-1
apply, together with the following.
NOTE Where the terms “voltage” and '“current” are used, they refer to r.m.s. values unless otherwise stated.
3.1
type A device
earth-leakage or open-circuit protective device generally designed to be built into the enclosure of a
transformer and not intended to be mounted outside a transformer without special precautions
NOTE A type A device normally protects only the transformer in which it is mounted.
3.2
type B device
earth-leakage or open-circuit protective device consisting of one or more separate elements so
designed that it can be mounted outside a transformer and housed in an enclosure that provides all
necessary protection according to its markings
NOTE 1 The enclosure may consist of the sign in which the device is mounted; the sign having a protection according to its
markings.
NOTE 2 The device may protect more than one transformer.

3.3
type C device
earth-leakage or open-circuit protective device that forms a non-replaceable part of a transformer and
which normally cannot be tested separately from the transformer
3.4
earth-leakage current
fault current flowing from a point in the output circuit to earth

transformer feeding the lamp circuit to fall below the respective shut-down current limit
3.6
shut-down current limit
secondary load current of a transformer at which an open-circuit protective device operates
NOTE Although the shut-down current limit is specified in terms of the current flowing in the output circuit, the manufacturer of
the device may measure this by other than direct means. Such means might include, e.g. measuring the current reflected into
the primary winding of the transformer or measuring a change in circuit power factor.
3.7
sensor
device that detects an earth-leakage current or, in the case of an open-circuit protective device,
detects when the secondary load current has fallen below the shut-down current limit, and either
causes a protective switch to operate or otherwise causes the output voltage of a transformer to be
removed

protective switch
part of an earth-leakage or open-circuit protective device that disconnects the mains supply from a
transformer
