Codmetel: HR000038

HT38 is essential to identify the circuit breaker protecting a given socket on a panel board without having to dissect it. 

HT38 includes a signal generator (HT38T) to be connected to the socket under test and a signal receiver (HT38R) capable of  "exploring" all RCCBs of the panel board.

Frequently questions from our customers:

Q: Why getting HT38?
A: Because it permits to detect the RCCB of the line without having to dissect it. Q: Should the receiver be brought into contact with the RCCB’s terminals?
A: No, you just need to put the receiver HT38R on the RCCB’s casing to detect the signal generated by the transmitter HT38T

Q: Which is the maximum distance between a socket and the corresponding RCCB to be detected?
A: The maximum distance between HT38T (connected to the above said socket) and HT38R is 300m (on networks with rated voltage of  110V L , N) and is 500m (on networks with rated voltage of  230V L , N)

Q: According which principle does the instrument work?
A: The instrument works according to PLT principle. HT38T releases a signal  into  the cable under  voltage which can be identified  by the receiver HT38R.
