What the ratings mean for fit
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 interrupting rating hits 187 kA at 240 VAC — that's the short-circuit current it can safely clear without welding contacts or rupturing the case. For a 415 VAC line it still holds 121 kA, and at 690 VAC it's 17 kA. That SCCR headroom means this breaker can sit upstream of a distribution panel without needing a current-limiting fuse ahead of it, as long as the available fault current stays under those numbers. Rated insulation voltage is 800 V. The undervoltage release (UVR) drops the breaker if control voltage falls below a set threshold. Max power loss at rated load is 40.5 W. 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. No ground-fault monitoring on this variant, no communication module, no voltage trigger. 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. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C. At 70 °C the breaker is rated 150 A.
