Switch-Disconnectors – P Range

For absolute safety


P1 switch-disconnectors for 25 A and 32 A		P3 switch-disconnectors for 63 A and 100 A		P5 switch-disconnectors for 125 A to 315 A

Like T rotary switches, P switch-disconnectors are manually-operated switching devices without any release or switch mechanism but with a direct link between manual operating element and the contact. The contacts are positively opened on de-energization, and the auxiliary contacts are interlocked opposing contacts.

P1 and P3 switch-disconnectors also enable N and/or HI functions to be added later with a make or break contact. In this case, the auxiliary make contact is always connected as a load-shedding contact for contactor control. The contactor thus carries the load switching power and the switch just has to disconnect the circuit.

Typical applications for P switch-disconnectors are described below.

Maintenance, repair and safety switches

P switch-disconnectors are suitable as safe maintenance and repair switches or as enclosed main switches for a single load.

Several padlocks can be fitted to it when in the Off position, thus ensuring life-saving safety requirements. Disconnection is visible and the equipment cannot be switched on again.

The safety switches comply with the specifications for safety-design of technical products to DIN 31000/VDE 1000.

On-Off switches

P switch-disconnectors provide reliable service for lighting and heating systems, motors etc.. They are also suitable for direct switching of motors to utilisation category AC-3. Their high switching capacity means that they can operate reliably where frequent On and Off switching is required.
