At 70 mm deep, 101.6 mm wide, and 130 mm tall, it fits standard 4-pole MCCB footprints in Siemens SENTRON panelboards. Front-side IP40 protection handles dry indoor environments; no trip indicator or undervoltage release is fitted on this variant.
The breaker carries 16 A without derating up to 55 °C ambient. Above that, it drops to 15 A at 60 °C, 65 °C, and 70 °C — a 6% reduction that matters if the panel runs hot near a transformer or drive bank. Maximum power loss is 10.6 W at rated current, which helps with enclosure heat budget.
