The Siemens SENTRON 3VA1116-5EE32-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated 160 A continuous at 40 °C, with a TM220 thermal-magnetic overcurrent release. The undervoltage release (UVR) drops the breaker if control voltage falls below a set threshold. The TM220 release means thermal pickup is fixed and magnetic pickup is adjustable — typical for general distribution protection where you want overload protection for cables and short-circuit protection for the bus. It's a straightforward line-protection breaker with a UVR coil for remote trip capability.
Panel integration
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a 3-pole MCCB footprint that fits standard Siemens SENTRON mounting plates and panel cutouts. The width is 3 inches exactly, matching the standard 3-pole MCCB slot pitch for busbar or cable connections. Depth of 70 mm (2.76 in) means it clears shallow enclosures without a deep gland plate. At 70 °C the breaker is rated 150 A.
