Product details

What this breaker carries

The Siemens 3VA2010-6HL42-0BF0 is a 4-pole IEC frame 100 MCCB rated 100 A with an Icu of 85 kA at 415 V — class H breaking capacity for high-fault industrial distribution. The ETU320 LI trip unit gives adjustable overload protection (Ir = 40…100 A) and short-circuit protection (Ii = 1.5…12 x In). N-conductor protection is selectable OFF, 50 %, or 100 % of phase current. An integrated undervoltage release (24 V DC) is fitted, so the breaker drops open on loss of control voltage — useful for emergency-stop or safety isolation circuits.

Mounting and integration

Mounts on a DIN rail or panel-mount via the 3VA2 frame. The nut keeper kit (included) secures cable lugs without separate hardware — reduces assembly time and torque-verification steps. The undervoltage release is factory-integrated; no field wiring of an external shunt trip required for loss-of-voltage protection.

Frequently asked questions

Where can I buy 3VA2010-6HL42-0BF0?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commercial response.

What breaking capacity does this MCCB have?

Icu = 85 kA at 415 V AC, class H per IEC 60947-2. That rating means it safely interrupts faults up to 85 kA without upstream cascading — suitable for high-fault industrial main or sub-feed distribution.

Does this breaker include an undervoltage release?

Yes, an undervoltage release (24 V DC) is integrated. Loss of control voltage causes the breaker to trip open — used in safety circuits or emergency-stop chains where a voltage-drop must de-energise the load.
