Current Protector Type E-1078-4.2 for low

Circuit Protection & Control
Current Protector Type E-1078-4.2
for low-voltage halogen lighting systems
Eliminating fire hazard
Technical Information.
Current Protector Type E-1078-4.2
(e.g. by overloads or short-circuit), the
Protector will immediately disconnect
the system. Underload (e.g. through
poor terminal connections) will also
cause system disconnection.
Fault conditions are indicated by the
integral LED. The system can be
re-set by turning the switch of the
lighting circuit off and then on again
once the cause of the failure has been
remedied.
