Eaton P3-63/EA/SVB Interruttore principale 63A 3 poli arresto di emergenza da incasso rosso/giallo

In industrial and commercial electrical installations, the ability to reliably disconnect power and provide emergency stop functionality is critical for safety and operational control. The Eaton P3-63/EA/SVB main switch addresses this need with a robust, panel-mounted solution that combines high switching capacity with clear visual status indication. This 3-pole switch (with neutral option) is rated for 63 A and up to 690 V AC, making it suitable for a wide range of power distribution and motor control applications. Its red handle and yellow locking ring ensure immediate recognition as an emergency stop device, while the lockable OFF position prevents unauthorized re-energization during maintenance.

Who is it for

This switch is ideal for electrical panel builders, machine OEMs, and maintenance engineers who require a dependable main disconnect or emergency stop switch for industrial machinery, control cabinets, and power distribution boards. It is particularly suited to applications where safety regulations demand a lockable isolation point and clear emergency stop indication.

Main features

• Rated operational current of 63 A and voltage up to 690 V AC, suitable for demanding industrial loads.
• 3-pole configuration with optional neutral (4-pole), providing flexibility for various circuit designs.
• Emergency stop function: red handle and yellow locking ring ensure high visibility and quick identification.
• Lockable in the OFF (0) position, allowing secure isolation during maintenance or repair.
