The OMB TRANSIENT SUPPRESSOR system has been conceived to protect against power surges. A set of arrestors make the transients not to reach the protected equipment and to turn off the transmitter using a recloser breaker. If the mains voltage is not within the preset parameters, the transmitter will be completely isolated from the mains. Once the mains voltage is within the preset parameters, the system resends a pulse that resets the circuit. This equipment is available for single and three phase 380V neutral systems with different current capabilities.
