Technical Parameters Parameter Specification Series / Product Type ABB Masterpact (MP) Series / Rotary Disconnect Switch (Load Break Switch) Order Code MP3-30R Number of Poles 3-Pole (3P) Rated Operational Current (Ie) 30 A (at 400V AC, AC-22A / AC-23A utilization category) Rated Operational Voltage (Ue) 690V AC Rated Insulation Voltage (Ui) 1000V AC Rated Impulse Withstand Voltage (Uimp) 12 kV Rated Short-Time Withstand Current (Icw) Typically 5 kA for 1 second (Must verify from specific datasheet. This is its ability to withstand a fault current without opening). Making & Breaking Capacity At 415V AC: Typically 30 A for normal service breaking (AC-23A). Utilization Category AC-22A (Switching of mixed resistive and inductive loads) AC-23A (Switching of motor loads or other highly inductive loads) Mechanical Life Typically > 10,000 operations Electrical Life Typically > 5,000 operations at rated current Operation Manual rotary handle (ON-OFF). Handle can be padlocked in the OFF position for safety lockout/tagout (LOTO). Mounting Fixed mounting for panel assembly. Connection Suitable for cable or busbar connection. Auxiliary Contacts Not included as standard. Often available as optional add-on modules (e.g., 1NO+1NC) for remote signaling of switch position. Standards Compliance IEC/EN 60947-1, IEC/EN 60947-3 (Specifically for switches, disconnectors, switch-disconnectors, and fuse-combination units) Ambient Temperature -25°C to +70°C (Operation)
