HELLERMANN ZONEMASTER surge PROTECTOR The ultimate answer to protecting circuits from incoming mains transients is to install a ZoneMaster across ring mains which apply mains to sensitive equipment. The unit is available in single or three phase versions. Modern working areas include a huge number of electrical devices which can create mains transients of thousands of volts. The ZoneMaster is simply wired IN PARALLEL with the building`s wiring as close to the incoming mains as possible. Therefore existing wiring does not have to be disturbed. It only carries the current associated with the transient, not the mains current flowing through the protected circuits. It can be connected directly across lines rated at up to 63 amps. It handles surge currents of up to 10,000 amps with a response time of less than 10 nanoseconds. The clamping circuit automatically resets after clamping modest transients. However after clamping a number of 10kA surges the energy handling capabilities of the unit`s first stage may be exceeded causing the unit`s internal fuses to operate safely disconnecting this stage. Three LEDS indicate status, green for Full Protection, red & green for Reduced Protection and red for No Protection. Single phase version (ring mains)
