The Siemens SENTRON 3VA2116-5KP32-0KC0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to that ceiling. It is designed for line protection in industrial distribution panels, with a short-circuit breaking capacity of 187 kA at 240 V AC and 121 kA at 415/440 V AC.
The 3VA2116-5KP32-0KC0 carries a rated ultimate short-circuit breaking capacity (Icu) of 187 kA at 240 V AC and 121 kA at 415/440 V AC. At 500 V AC it still holds 75.6 kA, and at 690 V AC it drops to 3.7 kA. Maximum power loss is 25.5 W, which matters for enclosure heat-load calculations.
Built-in accessories and communication
It also includes a communication function — the 3VA platform supports optional communication modules for PROFIBUS, PROFINET, or Modbus RTU, enabling power monitoring and remote reset capability. The undervoltage release is not fitted, so if undervoltage protection is needed, specify a different variant or add an external relay. The trip indicator is not present, meaning visual trip flag is absent — the auxiliary switches serve as the remote indication path.
Spring-cage terminals accept 0.2–2.5 mm² solid or ferruled stranded conductors — strip length 8 mm avoids whiskers under the cage.
