Main circuit connections are busbar-style front terminals. At 70 mm deep, 101.6 mm wide, and 130 mm tall, this 4-pole switch disconnector occupies the same DIN-rail footprint as the 3VA1 MCCB family. The 101.6 mm width (4 inches) is the standard 4-pole width for the IEC frame 160 — it will fill four module spaces on a DIN rail. Verify gland plate clearance for the front busbar terminals; the depth leaves room behind a 200 mm deep enclosure door. Maximum power loss is 38 W at rated current. ## Key selection detail: no overcurrent protection built in This is a switch disconnector, not a molded case circuit breaker. It has no thermal-magnetic or electronic trip unit. The description explicitly states \"without overload protection\" and \"without short-circuit protection.\" It is intended for isolation and switching duty where overcurrent protection is provided upstream or by a separate device. The UVR coil is the only integrated release — it drops the switch on undervoltage or remote trip via the control circuit.","metaTitle":"Siemens 3VA1110-1AA42-0DA0 Switch Disconnector, 100 A, 4-Pol","metaDescription":"Siemens SENTRON 3VA1110-1AA42-0DA0 switch disconnector, 100 A rated continuous current, 4-pole, IEC frame 160, with undervoltage release 208-230V AC.
