MCCB with shunt trip — 160 A, 3-pole, high interrupting capacity
Interrupting capacity reaches 242 kA at 240 V and 187 kA at 415 V, dropping to 3.7 kA at 690 V — the high 240 V figure suits low-voltage main or feeder duty where fault current can exceed 100 kA. The built-in shunt trip (STL) release allows remote tripping via a control signal, which is useful for emergency-stop or supervisory shutdown circuits.
Sizing and thermal performance
Insulation voltage rated 800 V.
Measures 105 mm wide, 181 mm high, 86 mm deep — a standard 3-pole MCCB footprint for 160 A frame size.
