Main switch disconnector P3-63/EA/SVB-SW/HI11 63A 3-pole 022264

Main disconnector – reliable disconnection and installation safety

This three-pole disconnector from Eaton, model P3-63/EA/SVB-SW/HI11, is a robust solution for disconnecting electrical circuits. Designed for both industrial and commercial building applications, it provides effective isolation and protection against overload. The device's construction allows for mounting in distribution boards, as well as serving as a main element in installations.

Functionality and application

The P3-63/EA/SVB-SW/HI11 disconnector is primarily a maintenance and main disconnector. Its cam mechanism-based design guarantees forced opening of the main contacts during switching off, increasing work safety. Additionally, the presence of auxiliary contacts (1 normally closed and 0 changeover) enables integration with control and signaling systems. This allows it to be used for remote circuit status monitoring or controlling other devices.

Applications for this disconnector include:

• Disconnecting equipment for maintenance or repair work.
• Isolating circuits in emergency situations.
• Providing safe power shut-off during downtime.
• Constructing main disconnection points in electrical installations.

Characteristics and benefits

The Eaton P3-63/EA/SVB-SW/HI11 disconnector stands out with several key features:

• High durability: Rated continuous current of 63A and switching capacity of 30 kW (at 400V) guarantee reliable operation even under heavy loads.
• Safety: Locking mechanism with a yellow ring allows securing the disconnector against accidental switching on, which is particularly important during service work.
• Versatility: Possibility of mounting on a plate, in distribution boards and indirect mounting increases application flexibility.
• Durability: Solid, permanently fixed device construction ensures long life and resistance to mechanical damage.
• Protection: IP65 protection class on the front side protects against dust and water, allowing it to be used in harsh environmental conditions.
• Status signaling: The presence of auxiliary contacts enables remote circuit status monitoring and integration with control systems.
• Compliance with standards: The device meets the requirements of IEC/EN 60947-3 standards, confirming its safety and reliability.

Additionally, it is worth mentioning the possibility of adding "HI 11" auxiliary contact modules, which allows adapting the disconnector's functionality to individual user needs. The normally closed auxiliary contact serves as a relief for the contactor, ensuring compliance with IEC/EN 60 204 and VDE 0113 standards – important when using the disconnector as a main switch.
