What this MCCB carries and where it fits
The Siemens SENTRON 3VA2116-5HL36-0CL0 is a 3-pole molded case circuit breaker rated 160 A continuous across the full -25 °C to 70 °C operating range — no derating curve to chase above 40 °C. It's designed for line protection, meaning it sits at the feeder or main distribution point, not downstream on a motor branch. The interrupting ratings are the headline: 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That SCCR headroom at 240 V tells you this breaker handles high-fault utility feeds without cascading upstream.
Auxiliaries and release — what's inside the can
This unit ships with an undervoltage release (UVR) and a full auxiliary switch complement: 2 auxiliary switches + 1 trip alarm switch + 1 electrical alarm switch HQ. That's enough status feedback for a PLC input card without adding external relays. The UVR means the breaker trips on loss of control voltage — standard for safety disconnects or emergency-stop chains where you want the main breaker to drop when the E-stop button is pressed.
Panel fit — dimensions and mounting
The breaker measures 86 mm deep, 105 mm wide, 181 mm tall. That's a standard 3-pole MCCB footprint — it drops into a SENTRON panelboard or a DIN-rail adapter without surprises. The 105 mm width is the same as the 3VA2 fixed-thermal family, so a panel laid out for a 160 A 3VA2 will accept this 5HL36 variant without re-drilling the mounting plate.
