The Siemens SENTRON 3VA2010-5HN36-0BH0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to the 70 °C operating maximum. Breaking capacity reaches 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V, covering most low-voltage distribution fault levels without cascading upstream. The breaker is configured for line protection (cable/feeder) and ships with an undervoltage release (UVR) plus 2 auxiliary switches and 1 trip alarm switch (HQ).
Lifecycle and Sourcing
This order code carries a current production lifecycle stage — the part is in active manufacture. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
Panel Fit and Integration
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — fits standard SENTRON 3VA panel cutouts and busbar systems. The 3-pole form factor occupies a single mounting position in a distribution board or MCC bucket. Power loss is 16 W maximum at rated load, which matters for thermal coordination inside sealed enclosures.
Auxiliary Functions and Release
The undervoltage release (UVR) trips the breaker when control voltage drops below a threshold — standard for safety disconnects on motor feeders or emergency-off circuits. The auxiliary switch configuration (2 aux + 1 trip alarm HQ) provides status feedback for PLC or SCADA monitoring: one set for breaker open/closed, one for trip indication. No communication function or ground-fault monitoring is built in; those are separate order-code variants.
