Abstract
An apparatus detects an E3 phase and E1 and E2 phases of an electromagnetic pulse (EMP). A pulse detector detects E1 and E2. A sustained level detector connects to a mains utility power supply line to detect E3. A delay timer holds an indication of a detected E1 or E2 for a predetermined time limit of about 10 minutes. A latch holds an indication that an EMP has occurred when an E3 occurs following an E1 or E2 within the predetermined time limit. An alarm indicates an EMP. A mechanical actuator disconnects the mains utility power supply line from utility power when an EMP is so indicated. The mechanical actuator can be mounted to a panel front face of a circuit breaker box in a configuration to push open a switch surface of a circuit breaker switch lever.
