Application

TSM8 dual rotary contact structure and the energy release system ensures stable and reliable protection, and has excellent current-limiting characteristics. Transparent aluminum cover protects your trip unit from settings, rotary handle, motor operation mechanism, etc, can be installed.

Working environment

1.The altitude belows 2000m;

2.Circuit breaker can be used between -25ºC and +70ºC. For temperatures higher than 40ºC (65 C for circuit breakers used to protect motor feeders). devices must be derated;

3.It can withstand the impact from humid air, salt spray, oil mist and mold;

4.It should be installed in places with no danger of explosion, no conductive dust, and no substance enough to corrode metal or damage the insulation;

5.In places with no rain and snow erosion;

6.Pollution degree

7.Installation category Ill.

Specification

Thermo-magnetic trip unit for TSM8-100~250

Protection

MIC 2.3 electronic trip unit for TSM8-400~630

Protection

Settings are made using the adjustment dials with fine adjustment possibilities.

Overload protection: long time protection(Ir)

Inverse time protection against overloads with an adjustable current pick-up lrsetusing a dial and a non-adjustable time delay tr.

Short-circuit protection: Short-time protection with fixed time delay(Isd)

Protection with an adjustable pick-up lsd.

Tripping takes place after a very short delay used to allow discrimination with the downstream device.

Short circuit instantaneous protection:(li)

lnstantaneous short-circuit protection with a fixed pick-up

MIC 5.0 electronic trip unit for TSM8-800~1600

Protection

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 lt 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 neutral protection at lr (4P 4d).

Indications

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.
