The 3-pole design with shunt trip (STL) and two auxiliary switches (HQ) makes it suitable for remote tripping and status feedback in motor control centers or main feeder applications.
This MCCB delivers 187 kA at 240 VAC, 121 kA at 415 V and 440 VAC, 75.6 kA at 500 VAC, and 3.7 kA at 690 VAC. The steep drop above 500 V reflects the arc extinction limits of the 160 A frame; at 690 V the part is still usable but only where fault current stays under 3.7 kA. For a 415 V distribution board fed by a typical 1 MVA transformer (prospective fault around 35–50 kA), the 121 kA rating gives comfortable margin without cascading upstream.
Footprint is 105 mm wide × 181 mm high × 86 mm deep — a standard 3-pole MCCB envelope that drops into existing SENTRON 3VA mounting bases. The 86 mm depth (3.39 in) leaves room for rear-access busbars in shallow enclosures. Shunt trip (STL) and two auxiliary switches (HQ) are factory-integrated; no field-add kit needed. Maximum power loss is 25.5 W at rated load — account for that in enclosed panel heat rise calculations.
