What this MCCB delivers for your line
The Siemens 3VA2116-5KP32-0CH0 is a SENTRON molded case circuit breaker rated for 160 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to that ceiling. Its 187 kA interrupting capacity at 240 V means it clears high-fault bolted shorts on a 240 V distribution bus without cascading upstream; at 415 V and 440 V it still holds 121 kA, and at 690 V it drops to 3.7 kA, so verify the available fault current at your service voltage. The 3-pole design with undervoltage release (UVR) and two auxiliary switches plus a trip alarm switch gives you remote status feedback and a drop-out on loss of control voltage — useful for a molding cell where a power sag could leave a hot runner uncontrolled.
Integration and panel fit
The 3VA2116-5KP32-0CH0 measures 105 mm wide, 181 mm high, and 86 mm deep — it mounts on a DIN rail in a standard distribution panel. The integrated communication function allows connection to a higher-level control system for remote monitoring and trip data, which is useful for tracking fault events on a molding line without walking the panel.
