Emergency-Stop switch

Rotary switches T and switch-disconnectors P with Emergency-Stop function

The use of rotary T switches or switch-disconnectors P as mains isolating devices with Emergency-Stop function is suitable for many applications.

These components in the range from 6.5 kW to 132 kW are extremely robust and compact in construction.
The handle directly operates the contacts and can be locked in the Off position using three individual padlocks.

Main switches with overload and short-circuit protection, as well as Emergency-Stop function, using the motorprotective circuit-breaker PKZ

Manufacturing and processing machines, nowadays are often constructed from several autonomous units whose individual power requirement is fairly low and does not need a high switching capacity.

The Emergency-Stop function can thus be set up simply and safely using a motor-protective circuitbreaker. The PKZ can be either actuated directly by hand using the Emergency-Stop mushroom button, or via the breaker mechanism in conjunction with an untervoltage release. In the latter case, the supply voltage to the undervoltage release that acts on the breaker mechanism is interrupted by operation of the Emergency-Stop button, and the mechanism trips the switch.
The PKZ can be re-closed only after the button has been released.

Circuit-breakers NZM and switch-disconnectors N, the Emergency-Stop switches for high currents

Circuit-breakers NZM and switch-disconnectors N are used wherever large loads must be switched and protected. In many applications, these switches form part of the Emergency-Stop equipment.
In the event of an emergency, the switches can be operated directly by means of the handle and disconnect the load, the system or the machine directly in all poles.

In the event of an emergency, the switches can be operated directly by means of the handle and disconnect the load, the system or the machine directly in all poles. An alternative method of disconnection in the event of danger is de-energization of the circuit-breakers and switchdisconnectors via their breaker mechanisms. Here, the supply voltage to the undervoltage release that acts on the breaker mechanism is interrupted by operation of an Emergency-Stop button, and the mechanism trips the switch. Once the button has been released, the circuit-breaker or switch-disconnector can be re-closed.
