Digital Electronic Overload Relay Motor Protector Thermal Overload Relay Samwha-Dsp EOCR-SSD120 Digital

Features

■ Compact Design
■ Overload / Phase Loss / Locked Rotor protection
■ Accurately display the working current (the highest current of L1 and L3) through the front panel LED display
■ When trip occurs, the cause is displayed on the LED window
■ Phase loss protection (3 seconds)
■ Convenient application: Selective use of single-phase (1P) and three-phase (3P) by DIP switch.
■ Optional contact output [fail-safe (N)/non-fail-safe (R)]: simplify the adjustment of the contact state
■ Easy installation due to both Din Rail and Panel Mounting

Used for

- Low Voltage Induced Electromotor (600V Level)
Protective Relay
- Break-Down Watch Current Relay
- Alternative Replacement for the Existing Relay

Protetcion

Protective Item Operating (Trip) Time

Over-Current = O-TIME

Phase Loss = 3 sec.

Locked Rotor = After D-time（Operating current> 200% of set current）

Set

After the installation is complete the settings as follows.

Set knob: D-TIME(Delay Time) Set two to three seconds longer than the motor starting time.

Set knob: O-TIME(Over-current run time) Set less than the motor's endurance time with over-current.

Set knob: Load(Rated Current) Set over 110% of the motor's rated current of under 120% of its operating current
