Main disconnect switch, 3-pole + 1NO + 1NC, 40A, emergency stop function, padlockable in OFF position, in a toughened glass housing, with MBS shielding plate, black knob with padlock lock P1-40/I2H/MBS/SVB-SW/HI11 199920

Main switch – reliable protection and comfortable operation

This Eaton Moeller® P1 main switch is a robust solution for safely disconnecting electrical installations. Designed to meet the requirements of both professional installers and end-users, it combines high functionality with a durable construction. Designed to operate at 690 V and 40 A, it provides effective protection of circuits against overload and short circuit. Equipped with three poles and auxiliary contacts (1NO and 1NC), it allows integration with control and signaling systems.

Construction and application

The switch is housed in a durable tempered glass enclosure, guaranteeing resistance to mechanical damage and external factors (IP65 protection). It has a padlockable lock in the off position, which further increases safety by preventing accidental re-engagement of the circuit during maintenance or service work. The presence of an MBS shielding plate minimizes electromagnetic interference, affecting the stability of connected devices. The black handle with a padlock provides convenient operation and additional protection against unauthorized access.

Key features and benefits

• High switching capacity: Rated operating power for AC-23 is 22 kW at 400 V, and for AC-3 – 15 kW at 400 V, allowing connection of even demanding receivers.
• Safety of use: Padlockable lock in the off position and high IP65 protection ensure maximum safety during operation and maintenance.
• Durable construction: Tempered glass housing and solid construction guarantee long device life even in harsh working conditions.
• Versatile application: Can be used as a main switch, repair switch and element of an emergency stop system, making it a universal solution for various applications.
• Easy installation: Designed for surface mounting (although there is no possibility of mounting on a plate or in distribution boards), which facilitates its installation in existing electrical installations.
• Compliance with standards: Meets the required safety standards, ensuring compliance with applicable regulations.
• Suitable for working with high inrush currents: C characteristic allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well.
• Locking option: Provides additional access control and prevents accidental device start-up during service or maintenance work.
• Status indication: The presence of auxiliary contacts (1NO and 1NC) allows integration with alarm signaling or process control systems.

This switch is characterized by a rated continuous current Iu of 40 A and is designed to operate at a rated voltage of 690 V.
