Eaton P3-63/I4-SI/HI11 2-Pole Rotary Main Switch, 63 A, 690 V AC, Grey/Red 207363

Rotary main switch with emergency stop function, rated at 63 A and 690 V AC. The P3-63/I4-SI/HI11 provides reliable load isolation and ON/OFF control in industrial and building installations. Its insulated grey enclosure and red handle ensure clear visual status, while the yellow locking ring allows padlocking in the OFF position for maintenance safety.

Advantages

High switching capacity of 30 kW at 400 V AC (AC-23A) and robust screw terminals support demanding applications. The IP65-rated enclosure protects against dust and water jets, making it suitable for harsh environments. Lockable in the 0 (Off) position to prevent accidental re-energization.

Suitable for

• Main switch for machine control panels
• Emergency stop disconnection in industrial plants
• Isolation of power distribution circuits up to 63 A
• Surface mounting in workshops and utility areas
