It is a pure disconnecting means — no overload or short-circuit protection elements inside — so it functions as a manual load-break switch for isolating a circuit under load, not as a circuit breaker. ## Undervoltage release and auxiliary switches This variant ships with a factory-fitted undervoltage release (UVR) coil rated for 24 V DC. The UVR does not include a leading contact, so the release coil and main contacts do not have a sequenced make/break relationship. The housing measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without surprises. Main circuit connections are front terminals (clamp type) accepting copper conductors; the front-access layout means the switch can be butted against adjacent devices on a busbar system without blocking wiring access. ## Thermal and electrical limits Maximum power dissipation at rated current is 38 W — a relevant number for enclosure thermal calculations when multiple disconnectors are ganged. Mechanical endurance is 15,000 operating cycles typical; no electrical endurance figure is listed, so cycle life under load depends on the switched current and voltage. ## What it does not include No trip indicator, no voltage-trip function, no communication interface, and no motor drive are fitted as standard — though the housing accepts an optional motor-drive extension for remote switching. The switch is not a circuit breaker; it provides no overcurrent or short-circuit protection downstream. For those functions, a 3VA MCCB or fuse combination must be added upstream.","metaTitle":"Siemens 3VA1110-1AA36-0BC0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens SENTRON 3VA1110-1AA36-0BC0 switch disconnector, 100 A rated, 3-pole, 690 V AC / 500 V DC, with undervoltage release 24 V DC and 2 HQ auxiliary switches.
