What this MCCB carries and where it fits
The Siemens 3VA2116-5HL36-0AC0 is a 3-pole SENTRON molded case circuit breaker rated for 160 A continuous current at 40 °C through 70 °C — no derating needed across that band, which simplifies panel schedules in warm enclosures or near crusher drives. Its breaking capacity hits 187 kA at 240 V and still holds 121 kA at 415 V, so it handles high-fault industrial feeds without cascading upstream — built for the pit where fault currents run hot. At 690 V the SCCR drops to 3.7 kA, so if your line runs 690 V, verify the available fault current stays under that threshold. Rated insulation voltage is 800 V, and the breaker is designed for line protection — no ground-fault monitoring, no undervoltage release, no communication module on this variant.
Panel fit and wiring constraints
Dimensions are 86 mm deep, 105 mm wide, 181 mm tall. The auxiliary switch block is pre-configured as 2 HQ auxiliary switches — no field addition needed for status feedback to the PLC. Maximum power loss is 25.5 W at rated load; factor that into enclosure thermal calculations, especially in sealed boxes near vibrating equipment.
