Analog Voltage Protection Relay- Output contact : 1 C/O (SPDT) rating : NO/5A, NC/3A, 250VAC- Trip setting : - Under voltage trip : -2.5% to -25% of 415VAC - Over voltage trip : -2.5% to -25% of 415VAC- Trip time setting : - Power On Delay : 400 msec - Trip time delay : 0.2 to 10sec- Accuracy : Trip setting ±5% of F.S, Time setting ±5%of F.S

Five types of time-limited characteristics can be selected, making it easy to study protection coordination. Built-in two types of instantaneous characteristics. The operating value of the 3-stage characteristic can be changed instantly, increasing the degree of freedom in considering protection coordination. The measured value and the control status of the relay can be displayed on the 7-segment display, and the monitoring status can be grasped at a glance. The changed value can be temporarily displayed on the 7-segment display, improving work efficiency in dark places. Since the operation value at the time of accident detection can be saved as an accident history, it is easy to narrow down the cause of the accident. An inspection contact has been added to the front, enabling operation tests of relays without entering the power receiving panel during inspection. By adopting a round body shape, it is easy to replace the conventional round body type relay. The opening direction of the front cover can be switched on either the left or right side according to the layout of the board equipment.

High operation reliability with high frequency noise and arc ground fault. Responds reliably to radio noise and arc ground faults. The earth fault relay and zero-phase current transformers OTG-N and OTG-D are individually compatible. (Any combination can be used because it is within the JIS standard error range) Coordination is easy because fine current settling is possible. Alarm terminals are installed on all models. The operating current setting part is a rotary switch type, so it is easy to set. A wide variety of circuit breaker removal methods, operating functions, and mounting methods.

This relay is a voltage protection relay.After detecting the voltage signal,the relay processes the input signal,judges if there is an overvoltage,undervoltage,phase failure,phase sequence,three-phase unbalance,PTC temperature and load error and controls the opration accurately and stably by means of the built-in microprocessor.
