Description of the h3+ communication system
2.1 h3+ electronic trip units
In addition to protecting against overloads and short-circuits, the h3+ moulded
case circuit breakers equipped with electronic trip units provide great flexibility and
fine-tuning capabilities for protection, improved selectivity values, and an extensive
range of electrical measurements as well as communication functions.
Overview of electronic trip units
Four versions are available:
- LSnI
- LSI
- LSIG
- Energy
The h3+ moulded case circuit breakers with electronic trip units are equipped with
PTA and MIP connectors to facilitate advanced use of the product.

PTA connector
The PTA connector, located on the side of the circuit breaker, enables an auxiliary
signal circuit to be connected to the overload pre-alarm output contact. The
threshold of this pre-alarm is set at 90% of the Ir setting on LSI or LSIG versions
and can be adjusted on the Energy version.

MIP connector
The MIP connector on the front face is used to connect the HTP610H h3+
configuration tool in order to test the tripping of the circuit breaker, configure the trip
unit parameters and perform diagnostics on the circuit breaker.
