What this 3VA2010-5HL36-0AC0 is and what it does
The Siemens 3VA2010-5HL36-0AC0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection in distribution panels. It's a 3-pole unit rated for 100 A continuous current, sized to protect feeder cables and downstream equipment in commercial and industrial power systems up to 800 V insulation class. The breaking capacity is the headline number here: 187 kA at 240 VAC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. That 187 kA at 240 V means this breaker can safely interrupt a fault current up to 187,000 amps without welding contacts or rupturing the case — critical for high-fault installations near large transformers or in industrial mains. The continuous current rating holds flat at 100 A from 40 °C all the way up to 70 °C ambient — no derating needed in a warm panel. That's unusual for an MCCB; most start dropping current above 40 °C. It means this breaker can sit in a hot enclosure next to other heat sources and still deliver its full 100 A.
Sourcing and lifecycle status
The breaker ships with two auxiliary switches (HQ type) pre-installed, which saves panel-building labor. The supplied basic switch is order code 3VA20105HL360AA0 — that's the internal switching mechanism. If you're cross-referencing a panel built around a 3VA1110-5ED36-0AC0, note the frame size difference: the 3VA2010 is a larger frame (105 mm wide vs the 3VA1110's narrower footprint), so it won't drop into the same DIN-rail cutout without panel rework.
Physical fit and integration
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard SENTRON 3VA2 frame. It mounts on DIN rail or can be screw-fixed to a backplate. The 86 mm depth (3.39 in) means it clears most standard enclosure depths, but check your gland plate clearance if you're retrofitting into a shallow panel. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. That covers unheated warehouses and outdoor enclosures in most climates. Maximum power dissipation is 13.5 W — negligible for panel thermal budgeting, but worth noting if you're packing multiple breakers in a sealed enclosure.
