This places it as the branch-circuit protection device for motors drawing 70-90 A full-load current — typically 30-50 HP at 460 V, depending on motor efficiency and service factor. The operating temperature range of -20 to 60 °C covers standard indoor environments without derating. ## Active production — no lifecycle risk for BOM planning ABB provides standard compliance documentation including UL listing, CE marking, and RoHS/REACH declarations. The UL rating is specifically called out in the description, which simplifies acceptance for North American panel shops.","metaTitle":"ABB MS495-90 Manual Motor Protector, 70-90 A, 50 kA","metaDescription":"ABB MS495-90 manual motor protector, 3-pole, 70-90 A range, 50 kA breaking capacity.
