<p>A can interface between an electrical trip unit (102) of a circuit breaker is disclosed. The ETU (102) in the present invention is connected to the CAN communication module (104) via a FRC connector (106). The CAN module (104) consists of a CAN trans-receiver IC (118) which helps in the transmission and reception of messages between ETU (102) and its supplementary modules (120) via the CAN bus (108). The ETU (102) can communicate four different modules (120) viz., a temperature module (110), an earth leakage module (114), a relay module (116), and a digital module (112).</p> |
