Model significance: ZHRV5-02/A220 voltage relay, rated supply voltage AC220V, with protection of over-voltage and under-voltage, operating range AC160V~270V, setting …

Unlike switching type electromechanical relays with fixed and usually ill-defined operating voltage thresholds and operating times, protective relays have well-established, selectable, and adjustable time and current (or other operating parameter) operating characteristics.

Low voltage protection: when the voltage between the live cable and the naught cable of the input terminal is lower than the set value, it will activate the protection switch. Overcurrent protection: when the actual current is greater than or equal to 1.15 times the rated current for 3 seconds, it will activate the protection switch. 3 LED LAMP Power Under voltage protection - Over voltage protection Rated AC voltage 230V±10% and frequency 50Hz/60Hz Passing Max Current: 40A Max.

Design ZHRV2 series is smaller size than design ZHRV1 series, ZHRV2 series voltage can be AC440V . Used in air conditioning units, elevator machine room, pumps ,fans and other motor control applications, as protection of over-voltage. under voltage, phase failure, phase sequence an phase imbalance.

LED Lighting Surge Protection Modules The Over voltage setting is usually 110 to 130 percent of the normal operating voltage depending on the system requirement. If the voltage rises above than this level for the set amount of time then the tripping command issued by the relay and hence the system is isolated.
