Protection
Chart C-1
Protection thresholds and delays are set using the adjustment dials.
Offer standard long time delay setting module.
overload protection
True rms long-time protection.
Thermal memory: thermal image before and after tripping.
Short-circuit protection
Short-time(rms) and instantaneous protection.
Selection of l't type(ON or OFF)for short-time delay.
Neutral protection
On 3-pole circuit breakers, neutral protection is not possible.
On 4-pole circuit breakers, neutral protection may be set using a three-position switch: neutral unprotected (4P 3d), neutral protection at 0.5lr (4P 3d +N/2) or neutralprotection at lr (4P 4d).
lndications
Overload indication by alarm LED on the front; the LED goes on when the current exceeds the long-time trip threshold.
Test
A mini test kit or a portable test kit may be connected to the test connector on the front to check circuit-breaker operation after installing the trip unit or accessories.
