VII. Description of Control Panel (1) Overload long-time delay tripping current Ir setting, 9-steps setting (lr= 0.4/0.45/0.5/0.6/0.7/0.8/0.9/0.95/1.0 * In) (2) Overload long-time delay tripping timeTr (21 r tripping time), 5-steps setting (Tr=20,40,60,80,160s). (3) Short-circuit instantaneous current li setting, 7-steps setting (Ii= 1.5/2/4/6/8/10/11*ln). (4) Testing port is used for tripping simulation test. (5) Electronic trip protection characteristic curve. (7) Operation indicator: indicator flashes green during normal operation. (8) Overload indicator: indicator flashes red if the current...

Description of Control Panel VIII. Optional Accessories Installation Table Notes: 1. Standard mounting: AL/AX – left mount; SHT/UVT – right mount 2. SHT equipped coil anti-burning protection switch 3. Accessories of MCCB BM100, BM160 and BM250 (HE/RE/UE) right-side mount is not allowed. 4. The communication function takes 2 mounting space of AL(AX); therefore BM-100-E, 160E and 250E (HE/RE/UE), can only equip either communication or AL(AX)
